2015-07-10Make ALIGN(x) behave as ALIGN(.,x)Alan Modra2-2/+15
Inside output sections, ALIGN(.,x) uses a section-relative value for dot. The unary ALIGN always used the absolute value of dot. * ldexp.c (align_dot_val): New function. (fold_unary <ALIGN_K, NEXT>): Use it.

2015-05-15Support AMD64/Intel ISAs in assembler/disassemblerH.J. Lu4-4/+12
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.
