Subject: [PATCH] i386: Add HImode to VALID_SSE2_REG_MODE
Move explicit Himode handling for SSE2 XMM regnos from
ix86_hard_regno_mode_ok to VALID_SSE2_REG_MODE.
No functional change.
gcc/ChangeLog:
* config/i386/i386.cc (ix86_hard_regno_mode_ok):
Remove explicit HImode handling for SSE2 XMM regnos.
* config/i386/i386.h (VALID_SSE2_REG_MODE): Add HImode.
