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.
