Re: indent(1) support for gcc(1) 0b prefix
Romain Tartière [EMAIL PROTECTED] wrote on 26 Apr 2008 23:35: ... I was so wondering how useful(less) it was to support this extension in FreeBSD indent(1) program. The version of gcc provided with the base system does not support this syntax, and AFAIK, only the avr-gcc port support this kind of constructs... It will be useful. The new gcc 4.3 release supports this extension without addtional patches. I cite the changelog: Integer constants written in binary are now supported as a GCC extension. They consist of a prefix 0b or 0B, followed by a sequence of 0 and 1 digits. -- Frank Behrens, Osterwieck, Germany PGP-key 0x5B7C47ED on public servers available. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Using special CFLAGS for a single file without writing the rule

Hi Ruslan, hi all,
I don't know if you followed the thread on -arch@, but the outcome is
basically that SSP should be disabled for a couple of files:
lib/csu/*
gnu/lib/csu/* (reported by antoine@, but I couldn't verify this one)
lib/libc/sys/stack_protector.c
sys/kern/stack_protector.c
Antoine Brodin supplied a patch for the kernel part:
+kern/stack_protector.c standard\
+ compile-with${NORMAL_C:N-fstack-protector*}
As for lib/csu/*, this is straightforward, I just have to set
WITHOUT_SSP in the Makefile.
The hardest one is lib/libc/sys/stack_protector.c. I endeavored to find
a way to compile a single file with ${CFLAGS:N-fstack-protector*}, but I
found no recipe but writing the whole rule for this file. I would
really like to avoid this solution so as to not override bsd.lib.mk
settings.
Considering your big experience with the build infrastructure, I suspect
you would have a solution.
Either by using a special rule, or through a hack similar to
the one found in the last two lines of libc/Makefile.
Cheers,
