Binutils with MCST patches
bff0500d7a
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in the linker. === Patch description === This patch is composed of 3 changes: 1) The main change is the addition of the logic for merging a file whose Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to merge merge with ARMv8-R. Note that merging only occurs if the two profiles are identical or one is S (Application or Realtime) and the other is R. 2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop are updated according to capabilities of ARMv8-R and their BFD_ASSERT updated to reflect that the logic is valid for ARMv8-R. 3) 2 build attribute merging tests are added to test the first change. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * elf32-arm.c (using_thumb_only): Update list of architectures in BFD_ASSERT for which the logic is valid. (using_thumb2_bl): Likewise. (using_thumb2): Likewise and return true for ARMv8-R. (arch_has_arm_nop): Likewise. (tag_cpu_arch_combine): New v8r table for ARMv8-R Tag_CPU_arch merging logic. Update commentis for value 15 of v8m_baseline, v8m_mainline and v4t_plus_v6_m arrays. Use v8r array to decide merging of value 15 of Tag_CPU_arch. ld/ * testsuite/ld-arm/arm-elf.exp (EABI attribute merging 11): New test. (EABI attribute merging 12): Likewise. * testsuite/ld-arm/attr-merge-11a.s: New file. * testsuite/ld-arm/attr-merge-11b.s: New file. * testsuite/ld-arm/attr-merge-11.attr: New file. * testsuite/ld-arm/attr-merge-12a.s: New file. * testsuite/ld-arm/attr-merge-12b.s: New file. * testsuite/ld-arm/attr-merge-12.attr: New file. |

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.
