as the bug report details some uses of -fpatchable-function-entry aren't happy with the "before" NOPs being inserted between global and local entry point on powerpc. We want the before NOPs be in front of the global entry point. That means that the patching NOPs aren't consecutive for dual entry point functions, but for these usecases that's not the problem. But let us support both under the control of a new target option: -msplit-patch-nops. gcc/ PR target/112980 * config/rs6000/rs6000.opt (msplit-patch-nops): New option. * doc/invoke.texi (RS/6000 and PowerPC Options): Document it. * config/rs6000/rs6000.h (machine_function.stop_patch_area_print): New member. * config/rs6000/rs6000.cc (rs6000_print_patchable_function_entry): Emit split nops under control of that one. * config/rs6000/rs6000-logue.cc (rs6000_output_function_prologue): Add handling of split patch nops. |

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.
