Binutils with MCST patches

X32 TLSDESC sequences can be: 40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg ... 67 ff 10 call *foo@TLSCALL(%eax) or the same sequence as LP64: 48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg ... ff 10 call *foo@TLSCALL(%rax) We need to support both sequences for x32. For both GDesc -> IE/LE transitions, 67 ff 10 call *foo@TLSCALL(%eax) should relaxed to 0f 1f 00 nopl (%rax) For GDesc -> LE transition, 40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg should relaxed to 40 c7 c0 fc ff ff ff rex movl $foo@tpoff, %reg For GDesc -> IE transition, 40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg should relaxed to 40 8b 05 00 00 00 00 rex movl foo@gottpoff(%rip), %eax PR gold/25426 * x86_64.cc (Target_x86_64<size>::Relocate::tls_desc_gd_to_ie): For x32, relax "rex leal foo@tlsdesc(%rip), %reg" to "rex movl foo@gottpoff(%rip), %eax" and relax ""call *(%eax)" to "nopl (%rax)". (Target_x86_64<size>::Relocate::tls_desc_gd_to_le): For x32, relax "rex leal foo@tlsdesc(%rip), %reg" to "rex movl foo@tpoff, %eax" and relax "call *foo@tlscall(%eax)" to "nopl (%rax)". * testsuite/Makefile.am (tls_test_gnu2.o): Depend on gcctestdir/as. (tls_test_file2_gnu2.o): Likewise. (tls_test_c_gnu2.o): Likewise. * testsuite/Makefile.in: Regenerated. |

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.
