of a power of two are represented as a shift.

Brian Gaeke dd306efa11 Just incorporating some notes I wrote for myself into a place where they won't 
get lost...

Vikram S. Adve 7dc5b6707c For instructions in a delay slot of another instruction, 
we no longer need to find the live-before set of the delayed
branch since that set is now included the live-before/after
set of the instructions in each delay slot.  Just assert that instead.

llvm-svn: 7796
 2003-08-12 22:22:24 +00:00
Vikram S. Adve 869b11b7c4 For an instruction with delay slots, mark all live values before 
the instruction as being live before/after the delay slot
instructions as well.

Brian Gaeke 709a16a0bc Give std::map<BasicBlock *, BasicBlock *> the short name BBMap, because 
it's used 7 different times.
Rename `getBackEdges' to `findAndInstrumentBackEdges', for clarity.
Remove some excess whitespace and commented-out code.
Use shorter forms of CallInst ctors.
Do not make `reopt_threshold' visible to the LLVM program, and do not
 pass it to the call to `reoptimizerInitialize'.  Don't pass the
 GlobalVariable representing it to any of our helper methods.
 `reopt_threshold' is an internal parameter of the reoptimizer, which
 InstLoops does not need to know about.

Brian Gaeke b7a8388b8c Add FunctionPassManager - it's like a PassManager, but it only deals in 
FunctionPasses.

Chris Lattner 9a59f58d90 Add a new -enable-cygwin-compatible-output argument, which make the output more 
consumably by the cygwin assembler.  This is really just a nasty hack until we
get real target triple support.

Also: Refactor implicit-uses printing into its own method.
Remove a couple of unused variables.

llvm-svn: 7720
 2003-08-11 14:59:53 +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
