The problem here is __builtin_shuffle when called with two arguments instead of 1, uses a SAVE_EXPR to put in for the 1st and 2nd operand of VEC_PERM_EXPR and when we go and gimplify the SAVE_EXPR, the type is now error_mark_node and that fails hard. This fixes the problem by adding a simple check for type of operand of SAVE_EXPR not to be error_mark_node. OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions. gcc/ChangeLog: PR c/94726 * gimplify.c (gimplify_save_expr): Return early if the type of val is error_mark_node. gcc/testsuite/ChangeLog: PR c/94726 * gcc.dg/pr94726.c: New test. |

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.
