@ Valid setups for veneer generation
Add support for stable secure gateway veneers addresses 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.

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.
