+
+ * 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.
