defaults.h (TARGET_MEM_CONSTRAINT): New target macro added.
2008-05-27 Andreas Krebbel <krebbel1@de.ibm.com>
* defaults.h (TARGET_MEM_CONSTRAINT): New target macro added.
* postreload.c (reload_cse_simplify_operands): Replace 'm'
constraint with TARGET_MEM_CONSTRAINT.
* recog.c (asm_operand_ok, preprocess_constraints,
constrain_operands): Likewise.
* regclass.c (record_reg_classes): Likewise.
* reload.c (find_reloads, alternative_allows_const_pool_ref):
Likewise.
* reload1.c (maybe_fix_stack_asms): Likewise.
* stmt.c (parse_output_constraint, parse_input_constraint):
Likewise.
* recog.h: Adjust comment.
* genpreds.c (generic_constraint_letters): Remove 'm' constraint.
* genoutput.c (note_constraint): Don't emit error for 'm'
constraint.
* doc/md.texi: Add a note to description of 'm' constraint.
* doc/tm.texi: Document the new TARGET_MEM_CONSTRAINT macro.
