- Backport from FSF mainline:
-
- gcc/
- * gengtype-lex.l: Add HARD_REG_SET.
- * expr.c (expand_expr_real_1): Record writes to hard registers.
- * function.h (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/
- * gcc.target/arm/frame-pointer-1.c: New test.
- * gcc.target/i386/pr9771-1.c: Move code out of main to allow frame
- pointer elimination.
