Currently patchable area is at the wrong place. It is placed immediately after function label and before .cfi_startproc. A backend should be able to add a pseudo patchable area instruction durectly into RTL. This patch adds patch_area_size and patch_area_entry to crtl so that the patchable area info is available in RTL passes. It also limits patch_area_size and patch_area_entry to 65535, which is a reasonable maximum size for patchable area. gcc/ PR target/93492 * cfgexpand.c (pass_expand::execute): Set crtl->patch_area_size and crtl->patch_area_entry. * emit-rtl.h (rtl_data): Add patch_area_size and patch_area_entry. * opts.c (common_handle_option): Limit function_entry_patch_area_size and function_entry_patch_area_start to USHRT_MAX.

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.
