The heurstics that was added for PR71016, try to search to see if the conversion was being moved away from its definition. The problem is the heurstics would stop if there was a non GIMPLE_ASSIGN (and already ignores debug statements) and in this case we would have a GIMPLE_LABEL that was not being ignored. So we should need to ignore GIMPLE_NOP, GIMPLE_LABEL and GIMPLE_PREDICT. Note this is now similar to how gimple_empty_block_p behaves. Note this fixes the wrong code that was reported by moving the VCE (conversion) out before the phiopt/match could convert it into an bit_ior and move the VCE out with the VCE being conditionally valid. Bootstrapped and tested on x86_64-linux-gnu. Also built and tested for aarch64-linux-gnu. PR tree-optimization/116098 gcc/ChangeLog: * tree-ssa-phiopt.cc (factor_out_conditional_operation): Ignore nops, labels and predicts for heuristic for conversion with a constant. gcc/testsuite/ChangeLog: * c-c++-common/torture/pr116098-1.c: New test. * gcc.target/aarch64/csel-1.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.
