![]() After r14-1014-gc5df248509b489364c573e8, GCC started to emit directly a zero_extract for `(t1&0x8)!=0`. This introduced a small regression where ifcvt would not do the ifconversion as there is now a paradoxical subreg in the dest which was being rejected. Since paradoxical subreg set the whole register, we can treat it as the same as a reg in the two places. OK? Bootstrapped and tested on x86_64-linux-gnu and aarch64-linux-gnu. gcc/ChangeLog: PR rtl-optimization/110042 * ifcvt.cc (bbs_ok_for_cmove_arith): Allow paradoxical subregs. (bb_valid_for_noce_process_p): Strip the subreg for the SET_DEST. gcc/testsuite/ChangeLog: PR rtl-optimization/110042 * gcc.target/aarch64/csel_bfx_2.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.
