- Reply-to: gcc-bugzilla at gcc dot gnu dot org
When compiling applications with inline assembly (mostly mmx/sse/3dnow) the
compiler bails out with this error (or close to it):
can't find a register in class `BREG' while reloading `asm'
attached is the code that gives the error, thoug this example is only polling
the cpu for vender identification.
