Add tls le relax support and related relocs in bfd. New relocation related explanation can refer to the following url: https://github.com/loongson/la-abi-specs/blob/release/laelf.adoc This support does two main things: 1. Implement support for three new relocation items in bfd. The three new relocation items are shown below: R_LARCH_TLS_LE_ADD_R R_LARCH_TLS_LE_HI20_R R_LARCH_TLS_LE_LO12_R 2. ADD a new macro RELOCATE_TLS_TP32_HI20 Handle problems caused by symbol extensions in TLS LE, The processing is similar to the macro RELOCATE_CALC_PC32_HI20 method. 3. Implement the tls le relax function. bfd/ChangeLog: * bfd-in2.h: Add relocs related to tls le relax. * elfnn-loongarch.c: (loongarch_relax_tls_le): New function. (RELOCATE_TLS_TP32_HI20): New macro. (loongarch_elf_check_relocs): Add new reloc support. (perform_relocation): Likewise. (loongarch_elf_relocate_section): Handle new relocs related to relax. (loongarch_elf_relax_section): Likewise. * elfxx-loongarch.c: (LOONGARCH_HOWTO (R_LARCH_TLS_LE_ADD_R)): New reloc how to type. (LOONGARCH_HOWTO (R_LARCH_TLS_LE_HI20_R)): Likewise. (LOONGARCH_HOWTO (R_LARCH_TLS_LE_LO12_R)): Likewise. * libbfd.h: Add relocs related to tls le relax. * reloc.c: Likewise.

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; if with a libg++ release, see libg++/README, etc. 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.
