I found this info: https://stackoverflow.com/a/35061913
which suggests running: $ llc --version (to show supported architectures) $ llc -march=ARCH -mattr=help (to list "available CPUs" and "available features") So I found for my case: $ llc -march=x86 -mattr=help Available CPUs for this target: ... pentium-m - Select the pentium-m processor. ... And I modified my script to use: CFLAGS='-O3 -march=x86 -mtune=pentium-m' Unfortunately clang complains again: error: unknown target CPU 'x86' note: valid target CPU values are: (same old list) I hope someone can shed some light on all this. There seem to be others complaining from the lack of info. -- George _______________________________________________ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
