Brian Gaeke 25e766aca5 First draft of X86 LLC backend. This should be OK for small programs like
Shootout, but it has some issues with bigger programs. Work in progress.

Chris Lattner 22f54501be For 16 and 32-bit multiplies, use the IMUL instruction instead of the MUL instruction.
This allows us to not force the use of the EAX/AX registers!

Brian Gaeke f6de19a095 Rename many instructions to their Intel asm-compatible names. This
involves removing the [bwl] suffixes from instruction names, as well
as some other distinguishing marks (32/64/80 on fp insns, _i suffixes, etc.)

Lowercase all instr. names as well for consistency's sake.

Brian Gaeke 259fdbc230 Add Initialization and Finalization methods for the Printer pass,
to print various things on a module-by-module basis (currently, only the
former is used).

Don't print < > around names. The assembler can't take it.

Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.

Brian Gaeke ac94bab876 lib/Target/X86/X86TargetMachine.{cpp,h}: Add initial version

Brian Gaeke cf8c4f5fe4 lib/Target/Sparc/Sparc.cpp:
Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
  the corresponding -disable-strip and -d options, over here to the SPARC
  target-specific bits of llc. Rename -d to -dump-asm.

tools/llc/Makefile:
 Reindent. Add x86 library so that llc compiles again.

tools/llc/llc.cpp:
 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
  above.
 Allow user to select a backend (x86 or SPARC); default to guessing from
  the endianness/pointer size of the input bytecode file.
 Fix typos.
 Delete empty .s file and exit with error status if target does not support
  static compilation.

Misha Brukman 2969ec5266 * Changed Bcc instructions to behave like BPcc instructions
* BPA and BPN do not take a %cc register as a parameter
* SLL/SRL/SRA{r,i}5 are there for a reason - they are ONLY 32-bit instructions
* Likewise, SLL/SRL/SRAX{r,i}6 are only 64-bit
* Added WRCCR{r,i} opcodes

Misha Brukman 0941cd11c8 * Removed PreSelection pass because that is now done in the JIT
* Removed instruction scheduling as it is too slow to run in a JIT environment
* Removed other passes because they aren't necessary and can slow JIT down

Chris Lattner 06250116a8 Special case simple binary operator X op C
This avoid generating a register to hold C, which in turn speeds up the
  register allocator by a lot: ~9% on 164.gzip and ~17% on 256.bzip2.  This
  also speeds up other passes.  This also speeds up execution of the program
  marginally, and makes the asm much easier to read. :)

Misha Brukman cbbe7ac699 All store instructions really want 'rd' in the first field.
Special cases: STFSRx and STXFSRx - they operate on predefined rd=0 or rd=1, and
expect %fsr as the parameter in assembly. They are disabled (since not used)
until an encoding, both for code generation and output, is chosen.

Brian Gaeke 98eee41e0e lib/CodeGen/Mapping/MappingInfo.cpp:
Update file comment to contain a bunch of the overview mapping-info
  documentation previously buried within the file.
 Remove some unnecessary include/using stmts.
 Rename pass to MappingInfoCollector.
 Rewrite a lot of it so it doesn't use global instance variables and so
  it outputs into MappingInfo objects and then dumps those out, instead of going
  straight to an assembly file.
 Change name of factory to getMappingInfoCollector.
 Fold prologue & epilogue writers into MappingInfo methods.

lib/Target/Sparc/FInfo.cpp:
 Correct file comment to reflect above change

lib/Target/Sparc/Sparc.cpp:

Tanya Lattner cbf828dd0d Had to comment out a line in outByte() to get it to compile because Out and tmp were

Misha Brukman efafdf8046 * Instead of re-inventing the MachineConstantPool emitter that's already given
in Emitter.cpp, just convert the Sparc version of the constant pool into
  what's already supported and inter-operate.
* Implemented a first pass at lazy function resolution in the JITResolver. That
  required adding a SparcV9CodeEmitter pointer to simplify generating
  bit-patterns of the instructions.
* SparcV9CodeEmitter now creates and destroys static TheJITResolver, which makes
  sense because the SparcV9CodeEmitter is the only user of TheJITResolver, and
  lives for the entire duration of the JIT (via PassManager which lives in VM).
* Changed all return values in the JITResolver to uint64_t because of the 64-bit
  Sparc architecture.
* Added a new version of getting the value of a GlobalValue in the
  SparcV9CodeEmitter, which now works for already-generated functions (JITted or
  library functions).
* Removed little-used and unused functions, cleaning up the internal view of the
  SparcV9CodeEmitter.
