 addPassesToEmitMachineCode now both take a FunctionPassManager.

llvm-svn: 7837

Get rid of RegisterLLC, which can't handle FunctionPasses anyway.

llvm-svn: 7836

 addPassesToEmitMachineCode now both take a FunctionPassManager.
Factory methods for function passes now return type FunctionPass *.

llvm-svn: 7835

This also enables -time-passes for FunctionPassManagers, which allows it to
be used for the JIT

 FunctionPassManager, to support function-at-a-time compilation and
 emission of code.

llvm-svn: 7821

Use a FunctionPassManager instead of a PassManager.

llvm-svn: 7820

Run passes on single function (hey, just-in-time compilation!)
 instead of the entire module that contains it.

llvm-svn: 7819

 on Function * when passing it to getPointerToFunction().

llvm-svn: 7818

 function-at-a-time compilation and emission of code.
Separate addPassesToEmitAssembly from addPassesToJITCompile, because
 the latter requires you to use FunctionPasses, and the former might
 diverge anyway.

llvm-svn: 7817

Correct one of the functions' comments.

Revert (to v1.55) one of the hunks of Chris's change that messed up the
 %-register workaround.

Add some comments and non-const methods to fix constness problems.

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.

the instruction as being live before/after the delay slot
instructions as well.

 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.
