re PR middle-end/44492 (auto-inc-dec pushes PRE_MODIFY/PRE_INC into inline asm operands)
PR middle-end/44492
* recog.h (struct recog_data): Add is_asm field.
* recog.c (asm_operand_ok, constrain_operands): If neither < nor > is
present in constraints of inline-asm operand and memory operand
contains {PRE,POST}_{INC,DEC,MODIFY}, return 0.
(extract_insn): Initialize recog_data.is_asm.
* doc/md.texi (Constraints): Document operand side-effect rules.
* g++.dg/torture/pr44492.C: New test.
