they make it less convenient to add new entries.

the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

This fixes PR5130.

which causes dependence info to be linked into lli.

they should not base it on llvm-db (which not following almost any "best practices").

Do away with the strange use of BitVectors in SSI, and just use normal sets.  This makes the code much more C++/LLVM-ish.

Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

- MingW needs -lpsapi (in ${LIBS}) linked after -lLLVMSystem.
  Noticed by Ronald Pijnacker!

- Some parts of the System library must be build with exceptions on windows.
  Based on a patch by Jay Foad!

MI->addOperand invalidates references to it's operands, avoid touching
the operand after a new one was added.

Remove neonfp attribute and instead set default based on CPU string. Add -arm-use-neon-fp to override the default.

question, can we get rid of the BasicBlock versions of all inserters
and use Head == 0 to indicate the old case when GetInsertBlock == 0?

llvm-svn: 83216

Restore the -post-RA-scheduler flag as an override for the target specification. Remove -mattr for setting PostRAScheduler enable and instead use CPU string.

Add support to extract lexical scope information from DebugLoc attached with an machine instruction. 
This is not yet enabled.

Use MachineFrameInfo.getPristineRegs() to determine which callee-saved registers are available for anti-dependency breaking. Some cleanup.

Change ld/st multiples to explicitly model the writeback to base register. This fixes most of the -ldstopti-before-sched2 regressions.
