| | | | | | | | | instruction set. This code adds support for the VEX prefix and for the YMM registers accessible on AVX-enabled architectures. Instruction table support that enables AVX instructions for the disassembler is in an upcoming patch. llvm-svn: 127644

* Eliminated the classification of control registers into %ecr_Sean Callanan2010-05-061-22/+11

* Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit Sean Callanan2009-12-191-0/+515
incarnations), integrated into the MC framework. The disassembler is table-driven, using a custom TableGen backend to generate hierarchical tables optimized for fast decode. The disassembler consumes MemoryObjects and produces arrays of MCInsts, adhering to the abstract base class MCDisassembler (llvm/MC/MCDisassembler.h). The disassembler is documented in detail in - lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime) - utils/TableGen/DisassemblerEmitter.cpp (table emitter) You can test the disassembler by running llvm-mc -disassemble for i386 or x86_64 targets. Please let me know if you encounter any problems with it. llvm-svn: 91749
