| | | | | | | | | | | | | | | code. It used to #include the enhanced disassembly information for the targets it supported straight out of lib/Target/{X86,ARM,...} but now it uses a new interface provided by MCDisassembler, and (so far) implemented by X86 and ARM. Also removed hacky #define-controlled initialization of targets in edis. If clients only want edis to initialize a limited set of targets, they can set --enable-targets on the configure command line. llvm-svn: 101179
* Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit Sean Callanan2009-12-191-0/+150
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
