llvm-svn: 7906

Many changes suggested by Chris. It's okay, I'll recover from the emotional
damage...maybe someday. :-)

Collapse ParseCStringVector into ParseStringVector.  Comment it.
Make it take a const input.
Use std::string::npos instead of -1 (what a mouthful!)
Make ParseEnvironmentOptions take const inputs.
Check its args at the very beginning.
Strdup all the contents of newArgv and free them all at the end.

include/Support/CommandLine.h:
Constify progName and envVar arguments to ParseEnvironmentOptions().

rounding up to a page, we need to request (num instrs * 4) bytes. However, I
think that 64 bytes is overkill for the stub function.

  registers are global, are NOT windowed, and hence can be clobbered!
* Removed unused register shorthand notations
* Fixed and cleaned up comments in inline assembly

another delayed instr. would cause the later sanity-check (assertion)
in PhyRegAlloc.cpp to fail, even though there is really no error.

llvm-svn: 7848

implement more constant expressions so that 176.gcc compiles with the CBE

llvm-svn: 7847

speeds up program execution by 15% pretty consistently for large programs

llvm-svn: 7845

to mark TableGen description files with "C++ mode".

 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

   (A <setcc1> B) logicalop (A <setcc2> B)  -> (A <setcc3> B) or true or false

Where setcc[123] is one of the 6 setcc instructions, and logicalop is one of: And, Or, Xor

 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.

llvm-svn: 7816

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