...answers. My immediate motivation is to improve the masked load/store ops for an AVX target. If we can fix scatter/gather similarly, that would be great. Can we legalize the same set of masked load/store operations for AVX1 as AVX2? If I'm understanding them correctly, the AVX1 FP instructions (vmaskmovps/pd) can be used in place of the AVX2 int instructions (vpmaskmovd/q), just with domain crossing penalties thrown in. I think we do this for other missing integer ops for an AVX1 target either in x86 lowering or in the tablegen patterns. Elena - I'm not too familiar with the vectorizers or scat...

Thanks Sanjay for highlighting this, few days back I also faced similar problem while generating masked store in avx1 mode, found its only supported under avx2 else we scalarize it. > 1) I did not switch-on masked_load/store to AVX1, I can do this. Yes Elena, This should be supported for FP type in avx1 mode (for INT type, I doubt X86 has masked_load/store instruction in avx1 mode).
