One problem with the cpuid instruction is that it uses %ebx which, when code is compiled as PIC for i386, is used as the PIC base register. This patch tries to handle this case by replacing the second register (%1) constraint with "=r", i.e. any (other) register, and swapping %ebx and %1 around the cpuid instruction. This patch could use a test, preferably on real i686 hardware. At least it needs some review and perhaps inspection of the generated assembler output. The idea and reasoning was taken from this comment: http://gcc.gnu.org/ml/gcc-patches/2007-09/msg00324.html |
