With many thanks to Andrew Gallatin and Roberto de Iriarte, I got the Compaq Java 2 running and wrapped it up with javavmwrapper while watching the Red Wings take their series against the Blues. Now I'll ask another question. With the ability to run Linux Java, what steps are required to get the native JDK (say 1.3) to compile? IIRC, the i386 port requires linux-java to build the native java, so that hurdle ~might~ be leaped. Take out the i386 requirement from the Makefile. Grab the jdk source from Sun and get the patches. Anything else? Anyone else try this? Advice? If this REALLY should be directed to the freebsd-java list, let me know. From monitoring that list, they seem more focused on i386 right now. p.s. - deepest apologies for the previous post in triplicate. Comcast's SMTP server opted to sit on my email for a few days, hence my second post attempt and Paul's forward. I'll give it a week next time!

That's more of a hacky workaround. The real fix would be to figure out why MODULE_DEPEND(linux, osf1, 1, 1, 1); does not work as it should.

On a sidenote, there used to be a JVM for the alpha by the name of CACAO, that promised very high performance, but, according to http://www.complang.tuwien.ac.at/java/cacao/index.html one would thought that development had been abandoned.

Yes. Its generally slower for integer & faster for floating point than x86 hardware of a similar vintage. However, if you want good floating point, you need to use the compaq ccc compiler. > This is difficult I know, cause Intel has Pentium II, III and other sorts - > but just some generally hint might help me. > > I'm just curious to find out if my Miata 500au is better than my Dual PPro > 200 MHz. Since you own the machines, this is easy. Whichever machine is faster for what apps you care about is better. You don't need any benchmarks.

Compaq ccc (for > Linux but usable under FreeBSD is reported to create much faster code > then gcc. I have not tried this myself. I can attest to this, though not under FreeBSD. When compiling the simple "flops.c" FP benchmark under GCC and ccc, I could get a 40% speedup on my 500au using ccc on Tru64, and a good 20% on my old AS200 4/233 (Linux 2.2.something and the Linux-native ccc) I also noticed a small but definite improvemnet in the speed and memory utiliaztion of Apache built with ccc vs. a gcc-built one. > In general: lots of YMMV here. Indeed. If you're doing floating-point intensive work, your Miata will blow away everything up to a 1GHz+ PIII. Integer... well, depends on your data and code, how much cache you have, etc. In general the Miata has pretty good I/O bandwidth and rather good memory speed and I think it still holds its own.

If you run 10 very intensive CPU processes on your Miata and on Pentium III 1GHz they will perform the same speed, in this case your miata = Pentium III 1GHz It depends also if hte progam you use is specint or specfp related program. I did this 10 concurrent processes test with the TSCP progam, and I got the result I told above.

BTW, you can't just say "Alpha 500 MHz". An EV6/500 in an ES40 is roughly twice as fast as an EV5/466 in an AS4100. >> Is Alpha faster, slower or generally the same ? > >FP faster, integer is ?? Note that correctly supporting IEEE FP will significantly hit Alpha performance - maybe 20-30% slower, _much_ worse if you have lots of non-finite numbers (denormals, infinities and NaNs). The hit should be slightly less on the latest AXP chips which support precise FP exceptions. My gut feeling is that an AS4100 EV5/466 is roughly on a par with a PII-266 integer-wise. At the low end, a Multia (LCA/166) is slightly better than a 486DX2-50 on worldstones. Since I'm currently waiting for it to finish - ssh between an ES40 EV6/500 and a PIII-600 suggests that the PIII-600 is around 50% faster at running blowfish. [In the last case, ssh and ssl were compiled using Compaq ccc with '-tune host -arch host' on the Alpha]. As someone else noted, memory and I/O bandwidth on most Alphas is far better than PCs. (The Multia and other LCA machines are probably the only exceptions).

Cryptographic code is usually not a very good benchmark for comparing a PC with a non-PC, unless what you are interesting in is actually performing that very same cryptographic operation. There are multiple reasons to that: -- Software which includes some cryptographic operation often uses a hand-made specially optimized assembly implementation for the PC, and a generic portable C implementation for everything else. Call it market pressure if you like. The bottom-line is that the generic portable implementation will not use more than 32 of the 64 bits of the Alpha. -- Some cryptographic algorithms are specially designed to fit well an architecture, and this architecture is often the PC. Blowfish was designed to be acceptable on all architectures, but this was in 1993, and in 1993 there was no problem in using byte-indexed arrays, which are more efficient on the PC than the Alpha. As extreme examples, one might speak of RC5 (completely PC-bound with data-dependant rotations of 32-bit values, which are very slow to perform on most non-PC architectures), and DFC (candidate to the AES normalization process, blazingly faster on the Alpha than on anything else because it uses a 64x64->128 bits multiplication). I have used as my main working machine a Miata for three years (under Linux first, then FreeBSD) and I came to the following conclusions: -- The PC will performe better than the equally-clocked Alpha on byte-intensive stuff, such as string handling, pattern matching and so. -- The Alpha will utterly crush the PC at floating point operations, especially when using the Compaq compiler. Actually, the Compaq compiler comes with an optimized math library (libcpml), slightly less precise but much faster. I compiled the "lame" MP3 encoder with gcc, and simply linking the binary with libcpml rather than the GNU libm yielded an executable thrice faster. -- The two preceeding conclusions are only mostly true. On any specific task, your mileage may vary greatly. --Thomas Pornin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Wed May 15 0:51:47 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from flood.ping.uio.no (flood.ping.uio.no [129.240.78.31]) by hub.freebsd.org (Postfix) with ESMTP id 4AFBF37B400 for ; Wed, 15 May 2002 00:51:44 -0700 (PDT) Received: by flood.ping.uio.no (Postfix, from userid 2602) id 4047B5307; Wed, 15 May 2002 09:51:42 +0200 (CEST) X-URL: http://www.ofug.org/~des/ X-Disclaimer: The views expressed in this message do not necessarily coincide with those of any organisation or company with which I am or have been affiliated.

It is not specific to the Alpha architecture, it is just that gcc is slow. I have been told that the register allocator in gcc uses an algorithm which is exponential in the number of available registers. A PC has 6 or 7 generic-purpose registers, an Alpha has 31... The Compaq compiler is slow also, but I think it is general sloppiness that is often seen in big software from big companies. It produces really good code, though (I often observed a 30% improvement in speed over gcc on generic integer code). I have been looking for a decent, fast C compiler on the Alpha, and I found none. Lcc is completely buggy on the Alpha/OSF, and is anyway not up-to-date with regards to C99. TenDRA was not fast, and seemed to be quite peckish about its own interpretation of what is portable.

It should probably also be mentioned that ev56 is "faster" than ev5 on much integer code because it has the BWX (byte) instructions which really help much common code written on 32-bit platforms.

The kernel overflowed it's stack. In SRM, you can try to debug this by using 'e sp' to get the stack pointer then get a stack dump and save a copy of it in a log or something, reboot the machine, then use gdb's list command on the kernel.debug to figure out the source:line for all the kernel-text addresses in the stack dump to figure out the backtrace. From that you can figure out where the recursion is happening and fix it. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Wed May 15 6:33:23 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from duke.cs.duke.edu (duke.cs.duke.edu [152.3.140.1]) by hub.freebsd.org (Postfix) with ESMTP id 3F6CD37B403 for ; Wed, 15 May 2002 06:33:12 -0700 (PDT) Received: from grasshopper.cs.duke.edu (grasshopper.cs.duke.edu [152.3.145.30]) by duke.cs.duke.edu (8.9.3/8.9.3) with ESMTP id JAA01944; Wed, 15 May 2002 09:33:11 -0400 (EDT) Received: (from gallatin@localhost) by grasshopper.cs.duke.edu (8.11.6/8.9.1) id g4FDWfu26750; Wed, 15 May 2002 09:32:41 -0400 (EDT) (envelope-from gallatin@cs.duke.edu) From: Andrew Gallatin MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-ID: <15586.25465.541559.66681@grasshopper.cs.duke.edu> Date: Wed, 15 May 2002 09:32:41 -0400 (EDT) To: Kris Kennaway Cc: alpha@FreeBSD.ORG Subject: Re: memory management fault during netbooting on 4.6-PRERELEASE In-Reply-To: <20020514235608.A69014@xor.obsecurity.org> References: <20020514235608.A69014@xor.obsecurity.org> X-Mailer: VM 6.75 under 21.1 (patch 12) "Channel Islands" XEmacs Lucid Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Kris Kennaway writes: > I'm seeing the following on the alpha package cluster when trying to > netboot a 4.6-PRERELEASE kernel: <...> > pc = 0x0 > ra = 0xfffffc000056bcc0 Something followed a null function pointer.

If a load or store is done to a misaligned address (a 32-bit load from an address starting on a 16 bit boundary, for example). These unaligned operations generate traps, and the kernel fixes up the load. This is very expensive, so the default is to print a warning when it happens. In a shell, you can use uac -s to cause programs to dump core when they generate an unaligned access, so that you can debug them. (assuming gdb worked on alpha in -current, which it doesn't; use the gdb52 port). You can also shut things up by using uac -p (or sysctl machdep.unaligned_print=0 to disable printing system wide).

There are many potential of them waiting for a small change elsewhere. One PR (alpha/34232) is open containing a fix for one of them, which might be the same you are seeing. I just did not found the time yet to check if the fix might leak some kernel internal data in the padding. Maybe we should just fill the padding with zeros. Can you please check if that's the same reason for your misaligned access? -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Wed May 15 11:19:58 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from gull.prod.itd.earthlink.net (gull.mail.pas.earthlink.net [207.217.120.84]) by hub.freebsd.org (Postfix) with ESMTP id 0AF5137B404 for ; Wed, 15 May 2002 11:19:55 -0700 (PDT) Received: from pool0412.cvx21-bradley.dialup.earthlink.net ([209.179.193.157] helo=mindspring.com) by gull.prod.itd.earthlink.net with esmtp (Exim 3.33 #2) id 1783NL-0007Ex-00; Wed, 15 May 2002 11:19:47 -0700 Message-ID: <3CE2A6A4.4F7C72A6@mindspring.com> Date: Wed, 15 May 2002 11:19:16 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Andrew Gallatin Cc: Dag-Erling Smorgrav , alpha@FreeBSD.ORG Subject: Re: memory management fault during netbooting on 4.6-PRERELEASE References: <20020514235608.A69014@xor.obsecurity.org> <15586.25870.79809.901266@grasshopper.cs.duke.edu> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Andrew Gallatin wrote: > > Dag-Erling Smorgrav writes: > > pid 43 (dhclient): unaligned access: va=0x11fff02c pc=0x1200271d4 ra=0x1200270fc > > An alpha needs to access memory in naturally aligned chunks.

You can also shut things up by using uac -p (or sysctl > machdep.unaligned_print=0 to disable printing system wide). FWIW, there's a bit you can set in CR3 from the 486 on up that will cause the same faults for unaligned access on x86 hardware. It's worth noting that there's a performance penalty for unaligned accesses there, too, though not as expensive as the trap+fixup on the Alpha, it does halve the data rate through the bus by doubling the number of bus cycles. For a 2.5GHz processor witha 433MHz front side bus, you are still talking ~ a factor of 6 on the CPU slowdown when doing I/O because of the relative clock rates, so doubling it moves it closer to a factor of 12. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Wed May 15 13:12:42 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from flood.ping.uio.no (flood.ping.uio.no [129.240.78.31]) by hub.freebsd.org (Postfix) with ESMTP id BECB437B40F; Wed, 15 May 2002 13:12:25 -0700 (PDT) Received: by flood.ping.uio.no (Postfix, from userid 2602) id CF3D95307; Wed, 15 May 2002 22:12:23 +0200 (CEST) X-URL: http://www.ofug.org/~des/ X-Disclaimer: The views expressed in this message do not necessarily coincide with those of any organisation or company with which I am or have been affiliated.

Then you want to do something like this: e -n 100 if that doesn't work then try: e -n 100 vmem: This should basically do a raw memory dump.

Recently i've run into a problem where booting a windoze 98 box on the local net crashes natd at the point someone logs into the desktop. This happens up through a buildworld on 5/13. I can restart natd after it crashes and all is well until the 98 box is rebooted. The message is: chorizo /kernel: pid 403 (natd), uid 0: exited on signal 10 (core dumped) I logged the traffic from that box through my firewall, and i know what packet is causing this: it's a udp packet from netbios (137) to my isp's dns server. chorizo /kernel: ipfw: 53 Accept UDP 10.0.0.33:137 NN.NN.NN.NN:53 in via dc0 If i put the accept rule before natd's divert rule, i get the expected 'out via xl0' line right after as the packet goes out the external card. If i put it after, natd crashes. I ran natd under gdb, and i've appended a small chunk of output below in case it suggests something obvious, but i don't know what to look for. Has anyone else run into this, or can anyone give me a hint where to look next in debugging the problem? BTW, Craig Burgess posted about a sig 10 in natd back in february under different conditions. I didn't see any replies, so i'm guessing this is the same problem...

Sounds like the most likely reason - especially considering BWX.

Quickly browsing the Spec CINT2000 Benckmark suite, i'd say, for most mysql usage, 197.parser and 255.vortex, might give you an idea of relative performance. Note that the system configurations used for this benchmarks are highly optimized, but, just for the comparison, let's think that the vendors's optimizations even out each other. (I will use CINT200-BASE numbers) An Intel PIII 1.0 Ghz Intel VC820 (Rambus Chipset) 133 Mhz FSB 197.parser 340 255.vortex 706 Alphas at 500 Mhz An oldie (AlphaStation 500/500) 21164A 8 Mb cache 197.parser 130 255.vortex 207 Also an oldie (DEC Personal Workstation 500 AU) 21164A 2 Mb cache 197.parser 124 255.vortex 203 Not that old (Dec-98) (AlphaServer DS20 Model 6/500) 21264 4 Mb cache 197.parser 206 255.vortex 400 So, i'd say an Intel PIII would be faster than an Alpha if your database application performance would be CPU bound. That is usually not the case (IBM Mainframes would have been given up a long time ago if it were!), so it would depend on the particular configuration of your systems. A big reason why old Alphas, Sun's, RS/6000's, etc have a long useful life lies in the good design of the IO subsystem and peripherals (Not multia of course :)) For that, you must think, in PC terms, about higher end server class machines that are not that cheap. Regards Roberto BTW, Reading the detailed results of the various SPEC benchmarks is much more usefull than reading the baseline number.

That seems to fix the crash, thanks. To answer your earlier 2 emails... yes, i have CPUTYPE=ev56 set in /etc/make.conf, and ldwu seems to be the winner, if i'm interpreting this correctly: Prepatch: pid 2704 (natd): unaligned access: va=0x11feb911 pc=0x120008994 ra=0x120008a04 op=0xc Postpatch: pid 384 (natd): unaligned access: va=0x11feb921 pc=0x120008994 ra=0x120008a04 op=ldwu Rich PS: as a side note, do you know why 'x/i' in gdb does not match the op= in the unaligned access line?

I think we already do this for current and get the swi_net: 18 unregistered isr stuff as a result (relating to ARP requests when you dhcp). Also, it might be nice to somehow track when ISR handlers are registered and deregistered using a backport of KTR or something similar so you can try to figure out what that ISR is supposed to be and see if that helps figure out the bug. However, that is a pretty good chunk of work, and just printing out the ISR if it's NULL might be a simpler first step. > Kris -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Wed May 15 21: 9:45 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from obsecurity.dyndns.org (adsl-64-165-226-162.dsl.lsan03.pacbell.net [64.165.226.162]) by hub.freebsd.org (Postfix) with ESMTP id 900B437B404; Wed, 15 May 2002 21:09:42 -0700 (PDT) Received: by obsecurity.dyndns.org (Postfix, from userid 1000) id E703866DC8; Wed, 15 May 2002 21:09:41 -0700 (PDT) Date: Wed, 15 May 2002 21:09:41 -0700 From: Kris Kennaway To: John Baldwin Cc: Kris Kennaway , alpha@FreeBSD.org, Andrew Gallatin Subject: Re: memory management fault during netbooting on 4.6-PRERELEASE Message-ID: <20020515210941.A1042@xor.obsecurity.org> References: <20020515210001.A742@xor.obsecurity.org> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-md5; protocol="application/pgp-signature"; boundary="82I3+IH0IqGh5yIs" Content-Disposition: inline User-Agent: Mutt/1.2.5.1i In-Reply-To: ; from jhb@FreeBSD.org on Thu, May 16, 2002 at 12:04:45AM -0400 Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org --82I3+IH0IqGh5yIs Content-Type: text/plain; charset=us-ascii Content-Disposition: inline On Thu, May 16, 2002 at 12:04:45AM -0400, John Baldwin wrote: > Well, ideally we would like to know which ISR is (mis)firing.

Could it be the same problem? Hmm, yes, that would be the same type of thing. Peter would know more about this than I would. If you stick in a printf and it turns out the troublesome ISR is 18 then I'm fairly sure it is arp and Peter might have some suggestions about a solution. > Kris -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Thu May 16 0:23:47 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from flood.ping.uio.no (flood.ping.uio.no [129.240.78.31]) by hub.freebsd.org (Postfix) with ESMTP id 7DE0C37B403; Thu, 16 May 2002 00:23:44 -0700 (PDT) Received: by flood.ping.uio.no (Postfix, from userid 2602) id F09DB5307; Thu, 16 May 2002 09:23:41 +0200 (CEST) X-URL: http://www.ofug.org/~des/ X-Disclaimer: The views expressed in this message do not necessarily coincide with those of any organisation or company with which I am or have been affiliated.

Bugs in the pagefault handler make the behaviour for invalid pointers very bad. The main one trap_pfault() doesn't give up immediately if the pagefault is from within ddb. In old versions of FreeBSD, this is probably only fatal if trap_pfault() blocks, but in -current is is fatal in the usual case where trap_fault() acquires a sleep lock.

After I discovered the reason, I toyed some more with the fixes and I think the cure is worse than the cause. The problem is that some kernel functions/ioctls which export data to userland are not 64bit friendly because of missing padding -- not in the structures, but how they are used. You will find some comments by itojun(?) in the NetBSD sources where he states the same. What happened for my case is that the interfaces got reported by an ioctl and I had IPv6 addresses on the interfaces. Unluckily, IPv6 address are not x*8 in size, but rather x*8+n. Now the kernel allocates one chunk of contigous memory for all interface addresses and starts to fill them in. This means that the next sa_address following an IPv6 entry will start at an unaligned address. I was using 'dhclient', too, and did observe the same behaviour and tracked it to the same place with gdb in -STABLE (the first IP6 address is one of the fec80, so the first "real" IPv6 address will trigger this). So, to fix this, you'd have to change the layout of the addresses in the chunk *and* fix all applications to behave accrodingly, otherwise they'd read from the wrong offset. That's where SA_ALIGN came into play, which does exactly that. Maybe you could just add trailing padding to the IP6-struct in the header and rebuild world ;) However, YMMV, and the bug DES reported might already be something else. Some patches are still lying around on my disks, but remember, you have to fix the kernel and the userland :-/ Volker To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Fri May 17 8:21:42 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from duke.cs.duke.edu (duke.cs.duke.edu [152.3.140.1]) by hub.freebsd.org (Postfix) with ESMTP id B2DBF37B414; Fri, 17 May 2002 08:21:11 -0700 (PDT) Received: from grasshopper.cs.duke.edu (grasshopper.cs.duke.edu [152.3.145.30]) by duke.cs.duke.edu (8.9.3/8.9.3) with ESMTP id LAA16158; Fri, 17 May 2002 11:21:11 -0400 (EDT) Received: (from gallatin@localhost) by grasshopper.cs.duke.edu (8.11.6/8.9.1) id g4HFKfI47274; Fri, 17 May 2002 11:20:41 -0400 (EDT) (envelope-from gallatin@cs.duke.edu) From: Andrew Gallatin MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-ID: <15589.8136.958487.689590@grasshopper.cs.duke.edu> Date: Fri, 17 May 2002 11:20:40 -0400 (EDT) To: John Baldwin Cc: obrien@FreeBSD.org, alpha@FreeBSD.org, Jeff Roberson , Doug Rabson , Alan Cox Subject: Re: gcc3 & alpha kernels In-Reply-To: References: <15587.55941.487432.408302@grasshopper.cs.duke.edu> X-Mailer: VM 6.75 under 21.1 (patch 12) "Channel Islands" XEmacs Lucid Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org John Baldwin writes: > > Does it work fine if you back out my hack to alpha/include/atomic.h where > I commented out the zapnot in atomic_cmpset_32()?

(eg, *p = 0xffffffff). No. ldl_l sign extends the 32-bit we load into a 64-bit register. The zapnot was clearing the upper 32-bits of the register to get back to a zero-extended unsigned 32-bit value. However, according to one of the GCC developer (see my latest commit) the Alpha ABI requires integer arguments to be sign-extended when passed regardless of signed/unsigned for the destination type b/c it maeks it easier sinec all the 'l' instructions (addl, ldl, etc.) do sign-extension. Thus, with 3.1 the zapnot isn't needed now. The fact that 2.95 needed it was possibly a bug. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message From owner-freebsd-alpha Fri May 17 9: 7:49 2002 Delivered-To: freebsd-alpha@freebsd.org Received: from duke.cs.duke.edu (duke.cs.duke.edu [152.3.140.1]) by hub.freebsd.org (Postfix) with ESMTP id AEBCB37B411; Fri, 17 May 2002 09:07:42 -0700 (PDT) Received: from grasshopper.cs.duke.edu (grasshopper.cs.duke.edu [152.3.145.30]) by duke.cs.duke.edu (8.9.3/8.9.3) with ESMTP id MAA17488; Fri, 17 May 2002 12:07:41 -0400 (EDT) Received: (from gallatin@localhost) by grasshopper.cs.duke.edu (8.11.6/8.9.1) id g4HG7Ba47335; Fri, 17 May 2002 12:07:11 -0400 (EDT) (envelope-from gallatin@cs.duke.edu) From: Andrew Gallatin MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-ID: <15589.10927.852559.251962@grasshopper.cs.duke.edu> Date: Fri, 17 May 2002 12:07:11 -0400 (EDT) To: John Baldwin Cc: alpha@FreeBSD.ORG Subject: Re: gcc3 & alpha kernels In-Reply-To: References: <15589.8136.958487.689590@grasshopper.cs.duke.edu> X-Mailer: VM 6.75 under 21.1 (patch 12) "Channel Islands" XEmacs Lucid Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org John Baldwin writes: > > On 17-May-2002 Andrew Gallatin wrote: > > > > John Baldwin writes: > > > > > > Does it work fine if you back out my hack to alpha/include/atomic.h where > > > I commented out the zapnot in atomic_cmpset_32()? > > > > Nope.
