In the Go 1.21 release the package internal/profile imports internal/lazyregexp. That works when bootstrapping with Go 1.17, because that compiler has internal/lazyregep and permits importing it. We also have internal/lazyregexp in libgo, but since it is not installed it is not available for importing. This CL adds internal/lazyregexp to the list of internal packages that are installed for bootstrapping. The Go 1.21, and earlier, releases have a couple of functions in the internal/abi package that are always fully intrinsified. The gofrontend recognizes and intrinsifies those functions as well. However, the gofrontend was also building function descriptors for references to the functions without calling them, which failed because there was nothing to refer to. That is OK for the gc compiler, which guarantees that the functions are only called, not referenced. This CL arranges to not generate function descriptors for these functions.

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.
