New Revision: 5736

trunk/perl/buildlib/KinoSearch/Build.pm
Log:
To make atomic intrinsics available under GCC, override the default
architecture of 386 with "-march=i486". Consolidate handling of GCC versions
(which was supposed to be in a recent commit, but didn't make it).
+
+ # Tell GCC to compile with a target architecture of 486 rather than
+ # the default 386 so that intrinsic atomics will be available.
+ if ( $extra_ccflags !~ /-march=\w+/ ) {
+ $extra_ccflags .= "-march=i486 ";
+ }
that flag, while necessary on 32bit archs that I've tried, breaks compilation
immediately under 64bit archs with the message:
cc1: CPU you selected does not support x86-64 instruction set
