Sean Callanan	36eab80875	Fixes to the X86 disassembler: ... Made LEA memory operands emit only 4 MCInst operands. Made the scale operand equal 1 for instructions that have no SIB byte. llvm-svn: 91919	2009-12-22 21:12:55 +00:00
Sean Callanan	04cc307edd	Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit ... 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	2009-12-19 02:59:52 +00:00
