gcc/
* gengtype-lex.l: Add HARD_REG_SET.
* expr.c (expand_expr_real_1): Record writes to hard registers.
* function.c (rtl_data): Add asm_clobbers.
* ira.c (compute_regs_asm_clobbered): Use crtl->asm_clobbers.
(ira_setup_eliminable_regset): Remove regs_asm_clobbered.
Use crtl->asm_clobbers.
gcc/testsuite/
