tm.texi (TARGET_MD_ASM_CLOBBERS): Adjust wording to not imply that this is called once, independent of asms in code.
* doc/tm.texi (TARGET_MD_ASM_CLOBBERS): Adjust wording to not imply that this is called once, independent of asms in code. Adjust to now being pased output and input lists. Mention helper function decl_overlaps_hard_reg_set_p. * hooks.c (hook_tree_tree_tree_tree_3rd_identity): Rename from hook_tree_tree_identity and to take three trees, returning third. * hooks.h (hook_tree_tree_tree_tree_3rd_identity): Adjust the prototype. * stmt.c: include hard-reg-set.h before tree.h. (decl_overlaps_hard_reg_set_p): New function, broken out from... (decl_conflicts_with_clobbers_p): Call decl_overlaps_hard_reg_set_p. (expand_asm_operands): Pass output and input lists in call to targetm.md_asm_clobbers. * target-def.h (TARGET_MD_ASM_CLOBBERS): Define as hook_tree_tree_tree_tree_3rd_identity. * target.h (struct gcc_target.md_asm_clobbers): Take three tree parameters. * tree.h [HARD_CONST] (decl_overlaps_hard_reg_set_p): Prototype. * config/i386/i386.c (ix86_md_asm_clobbers): Adjust to three parameters, first two unused. * config/cris/cris.c (cris_md_asm_clobbers): Adjust to added parameters. Only add MOF to clobbers if there's no 'h' mentioned in constraint letters and MOF is not mentioned as a asm-declared register in neither of the input and output lists. From-SVN: r96923
