When packing relative relocations, x86 linker may load the same symbol table repeatedly, which can take a long time. On Intel Core i7-1195G7 with 32GB RAM, it takes more than 45 minutes to create an output with -pie -z pack-relative-relocs from an input with 208025 code sections. Cache the symbol table to reduce the link time to less than 2 seconds. On the same machine, creating 3.1GB clang executable in LLVM 21.1.3 debug build: user 55.39 seconds system 6.71 seconds total 65.80 seconds maximum set(GB) 10.43 page faults 2406941 PR ld/33765 * elfxx-x86.c (elf_x86_relative_reloc_record_add): Remove keep_symbuf_p. (_bfd_x86_elf_link_relax_section): Updated. Cache the symbol table to avoid loading it again. Signed-off-by: H.J. Lu <hjl.tools@gmail.com>
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README, and so on. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
