https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206303 Bug ID: 206303 Summary: 11.0-CURRENT -r294096 boot/powerpc/kboot/Makefile for TARGET_ARCH=3Dpowerpc (non-64, clang based): unsupported argument '-mppc64bridge' to option '-Wc,' Product: Base System Version: 11.0-CURRENT Hardware: ppc OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: markmi@dsl-only.net Not that I expected everything to work but I tried an amd64 based -r294096 = -> powerpc buildworld buildkernel based on base/projects/clang3.8.0-import for TARGET_ARCH=3Dpowerpc (non-64). This was WITH_BOOT=3D in the src.conf file. What stopped it was an attempt to use: -Wc,-mppc64bridge That was from: base/head/sys/boot/powerpc/kboot/Makefile (One of the SRCS in that Makefile is ppc64_elf_freebsd.c as well.) The command line getting the message is for compiling conf.c and also has a -mcpu=3Dpowerpc64 in it. But the error message is: cc: error: unsupported argument '-mppc64bridge' to option '-Wc,' As far as I can tell looking at the history this has possibly been true sin= ce 11.0-CURRENT -r276331 on 2014-Dec-28 when base/head/sys/boot/powerpc/kboot/Makefile was created. I may just be the fi= rst to have tried such a clang-based powerpc build sequence. It would appear that kboot should possibly only be built when TARGET_ARCH=3Dpowerpc64 and not when TARGET_ARCH=3Dpowerpc . Otherwise more= than clang likely has to be able to target powerpc64 specifics for a TARGET_ARCH=3Dpowerpc build. (But this is guess work on my part for the Fre= eBSD criteria for such things. But a stopped TARGET_ARCH=3Dpowerpc build when cl= ang based does not seem a likely intended result.) --=20 You are receiving this mail because: You are the assignee for the bug.=
