Hi Haochen,
The regression cases are caused by "targetm.scalar_mode_supported_p" I added
for scalar mode checking. XImode, OImode and TImode (with -m32) are not
enabled in ix86_scalar_mode_supported_p. So they're excluded from by pieces
operations on i386.
The original code doesn't do a check

Hi,
Vector mode instructions are efficient for compare on some targets.
This patch enables vector mode for compare_by_pieces. Two help
functions are added to check if vector mode is available for certain
by pieces operations and if if optabs exists for the mode and certain
by pieces operations. O
