2015-05-15Support AMD64/Intel ISAs in assembler/disassemblerH.J. Lu2-0/+9
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.

2015-04-08Add SHF_COMPRESSED support to gas and objcopyH.J. Lu8-3/+433
This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi} options to gas and objcopy for ELF files. They control how DWARF debug sections are compressed. --compress-debug-sections=none is equivalent to --nocompress-debug-sections. --compress-debug-sections=zlib and --compress-debug-sections=zlib-gnu are equivalent to --compress-debug-sections. --compress-debug-sections=zlib-gabi compresses DWARF debug sections with SHF_COMPRESSED from the ELF ABI. No linker changes are required to support SHF_COMPRESSED. bfd/ * archive.c (_bfd_get_elt_at_filepos): Also copy BFD_COMPRESS_GABI bit. * bfd.c (bfd::flags): Increase size to 18 bits.
