target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.
First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

(LLVMX86Utils.a) to break cyclic library dependencies between
LLVMX86CodeGen.a and LLVMX86AsmParser.a. Previously this code was in
a header file and marked static but AVX requires some additional
functionality here that won't be used by all clients. Since including
unused static functions causes a gcc compiler warning, keeping it as a
header would break builds that use -Werror. Putting this in its own
library solves both problems at once.

asm printer and lowering code in the printer subdir for the moment.

missing ones are libsupport, libsystem and libvmcore. libvmcore is
currently blocked on bugpoint, which uses EH. Once it stops using
EH, we can switch it off.
This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

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.

eliminate the GasBugWorkaroundEmitter class, but for now AT&T style emission
is not fully operational.

much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory). This makes the system cleaner and allows us to have a read-only
source tree.

Adjusted Makefile to work with new autoconf-style object root.
Specifically, use the new -I option of tblgen to find include files.
