--- Comment #5 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to Hongtao Liu from comment #4) > To clarify, the question originally came from whether or not to report error > for -m32,-march=native, and then LLVM folks said it's diffcult for LLVM not > issuing error for -march=native -m32, but issuing error for explicit -mapxf > -m32. So they want to just not issue error at all, and then comipler > silently disables the 64-bit only features(plus adding documents to mention > -m32 will disable those features). This is no different from PR 101395. I don't believe LLVM can't work like GCC.
