As noticed we are looking for INDIRECT_REF with allows_mem to avoid a copy since then we're sure the operand is in memory (assuming *& is folded). But INDIRECT_REFs are no longer a thing, the following replaces the check with a check for a MEM_REF with a non-ADDR_EXPR operand. This should fix the regression part without fully exploring all possibilities around tcc_reference operands. I've placed an assert that we do not see an INDIRECT_REF here. While we gimplify asm operands we never do any checking on its IL afterwards. 2022-03-09 Richard Biener <rguenther@suse.de> * cfgexpand.cc (expand_gimple_asm): Special-case MEM_REF with non-decl operand, avoiding a copy.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
