Hi freebsd-toolchain@freebsd.org, freebsd-i386@freebsd.org cc: freebsd-hackers@freebsd.org Sun Jul 17 01:19:37 UTC 2011 I wrote to freebsd-hackers@ with Subject: Freebsd-7.4 + std gcc 4.2.1 fails to honour -march=i586 Summary: I found a problem with CFLAGS += -march=i586 on an i686 linking a crt.o for an i686, then not running on an i586, I suggested maybe -march could be extended to also select seperate lib sub directories to at least trigger a link failure, rather than a silent apparent good compile of a bad binary. Others on freebsd-hackers@ made various follow up. People on freebsd-toolchain@ & freebsd-i386@ might have valuable input ? Not wanting to split the thread between lists, or cross post, More than this one) or lose people on freebsd-hackers@, Could you please look at http://lists.freebsd.org/pipermail/freebsd-hackers/2011-July/035889.html & reply-to: freebsd-hackers@freebsd.org Thanks ! (PS I'm not on freebsd-toolchain@ & freebsd-i386@, but am on freebsd-hackers@ ) Cheers, Julian -- Julian Stacey, BSD Unix Linux C Sys Eng Consultants Munich http://berklix.com Reply below, not above; Indent with "> "; Cumulative like a play script.
