This patch adds testing checks (goa_stabilize_expr with NULL pre_p) for more tree codes, so that we don't gimplify their operands individually unless lhs appears in them. Also, so that we don't have exponential compile time complexity with the added checks, I've added a depth computation, we don't expect lhs to be found in depth 8 or above as all the atomic forms must have x expression in specific places in the expressions. 2021-09-14 Jakub Jelinek <jakub@redhat.com> * gimplify.c (goa_stabilize_expr): Add depth argument, propagate it to recursive calls, for depth above 7 just gimplify or return. Perform a test even for MODIFY_EXPR, ADDR_EXPR, COMPOUND_EXPR with __builtin_clear_padding and TARGET_EXPR. (gimplify_omp_atomic): Adjust goa_stabilize_expr callers. |

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.
