TImode register referenced in debug insn can be converted to V1TImode by scalar to vector optimization. When converting a TImode store to V1TImode, we need to check all debug insns on its use chain to convert the V1TImode register to SUBREG TImode if source register is undefined. gcc/ PR target/72748 * config/i386/i386.c (timode_scalar_chain::convert_insn): Call fix_debug_reg_uses after changing source register mode to V1TImode if source register is undefined. gcc/testsuite/ PR target/72748 * gcc.target/i386/pr72748.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.
