2016-08-26 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * bfd-in.h (bfd_elf32_arm_set_target_relocs): Add a new parameter for the input import library bfd. * bfd-in2.h: Regenerate. * elf32-arm.c (struct elf32_arm_link_hash_table): New in_implib_bfd and new_cmse_stub_offset fields. (stub_hash_newfunc): Initialize stub_offset and stub_template_size to -1. (elf32_arm_add_stub): Likewise for stub_offset. (arm_new_stubs_start_offset_ptr): New function. (arm_build_one_stub): Only allocate a stub_offset if it is -1. Allow empty SG veneers to have zero relocations. (arm_size_one_stub): Only initialize stub size and template information for non empty veneers. Do not update veneer section size if veneer already has an offset. (elf32_arm_create_stub): Return the stub entry pointer or NULL instead of a boolean indicating success or failure. (cmse_scan): Change stub_changed parameter into an integer pointer parameter cmse_stub_created to count the number of stub created and adapt to change of return value in elf32_arm_create_stub. (cmse_entry_fct_p): New function. (arm_list_new_cmse_stub): Likewise. (set_cmse_veneer_addr_from_implib): Likewise. (elf32_arm_size_stubs): Define cmse_stub_created, pass its address to cmse_scan instead of that of cmse_stub_changed to compute the number of stub created and use it to initialize stub_changed. Call set_cmse_veneer_addr_from_implib after all cmse_scan. Adapt to change of return value in elf32_arm_create_stub. Use arm_stub_section_start_offset () if not NULL to initialize size of secure gateway veneers section. Initialize stub_offset of Cortex-A8 erratum fix to -1. Use ret to hold return value. (elf32_arm_build_stubs): Use arm_stub_section_start_offset () if not NULL to initialize size of secure gateway veneers section. Adapt comment to stress the importance of zeroing veneer section content. (bfd_elf32_arm_set_target_relocs): Add new in_implib_bfd parameter to initialize eponymous field in struct elf32_arm_link_hash_table. ld/ * emultempl/armelf.em (in_implib_filename): Declare and initialize new variable. (arm_elf_create_output_section_statements): Open import input library file for writing and pass resulting in_implib_bfd to bfd_elf32_arm_set_target_relocs. (PARSE_AND_LIST_PROLOGUE): Define OPTION_IN_IMPLIB option. (PARSE_AND_LIST_LONGOPTS): Define --in-implib option. (PARSE_AND_LIST_OPTIONS): Add help message for --in-implib option. (PARSE_AND_LIST_ARGS_CASES): Handle new OPTION_IN_IMPLIB case. * ld.texinfo (--cmse-implib): Update to mention --in-implib. (--in-implib): Document new option. * NEWS: Likewise. * testsuite/ld-arm/arm-elf.exp (Secure gateway import library generation): add --defsym VER=1 to gas CLI. (Secure gateway import library generation: errors): Likewise. (Input secure gateway import library): New test. (Input secure gateway import library: no output import library): Likewise. (Input secure gateway import library: not an SG input import library): Likewise. (Input secure gateway import library: earlier stub section base): Likewise. (Input secure gateway import library: later stub section base): Likewise. (Input secure gateway import library: veneer comeback): Likewise. (Input secure gateway import library: entry function change): Likewise. * testsuite/ld-arm/cmse-implib.s: Add input import library testing. * testsuite/ld-arm/cmse-implib.rd: Update accordingly. * testsuite/ld-arm/cmse-new-implib.out: New file. * testsuite/ld-arm/cmse-new-implib.rd: Likewise. * testsuite/ld-arm/cmse-new-implib-no-output.out: Likewise. * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out: Likewise. * testsuite/ld-arm/cmse-new-earlier-later-implib.out: Likewise. * testsuite/ld-arm/cmse-new-comeback-implib.rd: Likewise. * testsuite/ld-arm/cmse-new-wrong-implib.out: 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.
