2015-07-14Make default compression gABI compliantH.J. Lu1-0/+7
All programs in binutils+gdb git repo now support gABI compression with the SHF_COMPRESSED bit. This patch makes the zlib-gabi option as compression default for gas, gold, ld and objcopy, instead of the zlib-gnu option whose outputs are incompatible with gABI. binutils/ * objcopy.c (copy_file): Set BFD_COMPRESS_GABI if not zlib-gnu. * doc/binutils.texi: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. binutils/testsuite/ * binutils-all/compress.exp: Update. gas/ * as.c (parse_args): Make --compress-debug-sections and --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * doc/as.texinfo: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. gold/ * compressed_output.cc (Output_compressed_section::set_final_data_size): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * testsuite/Makefile.am (flagstest_compress_debug_sections.check): Expect ".debug_.*" with the SHF_COMPRESSED bit, instead of ".zdebug_". * testsuite/Makefile.in: Regenerated. ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * ld.texinfo: Change --compress-debug-sections=zlib to zlib-gabi. ld/testsuite/ * ld-elf/zlibbegin.rS: Updated to .debug_.* with the SHF_COMPRESSED bit. * ld-elf/zlibnormal.rS: Likewise.
2015-07-10Properly convert objects between different ELF classesH.J. Lu1-0/+9
The output SHF_COMPRESSED section size is different from input if ELF classes of input and output aren't the same. We must adjust the section sizes as well as the compression headers in SHF_COMPRESSED sections when converting objects between different ELF classes. bfd/ PR binutils/18656 * bfd.c (bfd_convert_section_size): New function.

2015-05-15Support AMD64/Intel ISAs in assembler/disassemblerH.J. Lu1-0/+5
AMD64 spec and Intel64 spec differ in direct unconditional branches in 64-bit mode. AMD64 supports direct unconditional branches with 16-bit offset via the data size prefix, which truncates RIP to 16 bits, while the data size prefix is ignored by Intel64. This patch adds -mamd64/-mintel64 option to x86-64 assembler and -Mamd64/-Mintel64 option to x86-64 disassembler. The most permissive ISA, which is AMD64, is the default. GDB can add an option, similar to (gdb) help set disassembly-flavor Set the disassembly flavor. The valid values are "att" and "intel", and the default value is "att". to select which ISA to disassemble. binutils/ PR binutis/18386 * doc/binutils.texi: Document -Mamd64 and -Mintel64. gas/ PR binutis/18386 * config/tc-i386.c (OPTION_MAMD64): New.
