Binutils with MCST patches
b287eca391
There are extensions to 386 psABI: https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs to call tls_get_addr via GOT: call *___tls_get_addr@GOT(%reg) where EBX register isn't required as GOT base. Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, 7-byte lea instruction before call instruction is replaced by 6-byte one to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte lea instruction. PR gold/20308 * i386.cc (Target_i386::Relocate::relocate): Allow R_386_GOT32X relocation against ___tls_get_addr. (Target_i386::Relocate::tls_gd_to_ie): Support indirect call to __tls_get_addr.

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.
