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. (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.
