Chris Lattner e5b80dfdf1 Until the pattern matching instruction selector is finished, enable debug output from it

2003-08-11 15:11:01 +00:00
Chris Lattner e61db425e8 Add support for a pattern matching instruction selector. This is still in
the early implementation phases, so it is disabled by default

Misha Brukman 1fe74d144b Implement LLVM intrinsics `llvm.setjmp' and `llvm.longjmp' as follows:
* setjmp() simply returns 0
* longjmp() simply calls abort()

Vikram S. Adve 6e4a358f72 Fix sanity-checking in 'maskUnsigned' code to be more precise:
use or def-and-use operands can be substituted after one def-only
operand has been substituted.

Misha Brukman 8f18938d1c * Renamed option from `nopreselect' to `nopreopt' since it disables more than
just PreSelection
* Wrapped code at 80 columns
* Added the DecomposeMultiDimRefs Pass to the JIT compilation path

Misha Brukman 79226d066e Use the registers g1 and g5 as temporaries for making far jumps and far calls,
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown
memory in other functions, standard libraries, and worse.

In addition, this has the benefit of improving JIT performance because we
eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2
stores.

Vikram S. Adve 792b48f4d1 1. Bug fix: was using SLL instead of SLLX for ULongTy. Chump.
2. Handle fp-to-uint conversions directly here instead of relying on
   a pre-transformation to replace them with the 2-step conversion.
3. Use size rather than explicitly checking types when deciding what
   opcodes to use, wherever possible.  This is less error prone (the
   bug fix above was not the first time!).
4. Float-to-pointer casts shd now work though this hasn't been tested.

Vikram S. Adve 26125cbeb5 Remove conversion of fp-to-uint cast into a multi-step cast:
this is not an optional transformation on SPARC and is now handled
directly by instruction selection.

Misha Brukman 4510698acb SparcV9CodeEmitter.cpp:
* Doxygen-ified comments
* Added capability to make far calls (i.e., beyond 30 bits in CALL instr)
  which implies that we need to delete function references that were added by
  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)
* Cleaned up code that generates far jumps by using an array+loop

SparcV9CodeEmitter.h:
* Explained more of the side-effects of emitFarCall()

  Instruction.
