multiply sequence when the power is a constant integer.  Before, our
codegen for std::pow(.., int) always turned into a libcall, which was
really inefficient.

This should also make many gfortran programs happier I'd imagine.

on integers as well and codegen should lower them to branch trees.

Allow targets to specify the return type of libcalls that are generated for floating point comparisons, rather than hard-coding them as i32.

mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.

do illegal stuff around it.  No testcase because the issue is very fragile.

interesting part of this is the divrem changes, which are
already tested by CodeGen/X86/divrem.ll.

static inline functions with macros.

instead use the appropriate subreggy thing.  This generates identical
code on some large apps (thanks to Evan's cross class coalescing
stuff he did back in july).  This means that MOV16r0 can go away
completely in the future soon.

Certain Thumb instructions require only SP (e.g. tSTRspi).

llvm-svn: 91944

because the Visual C++ build does not build .c files as C99

llvm-svn: 91935

Made LEA memory operands emit only 4 MCInst operands.
Made the scale operand equal 1 for instructions that have no
SIB byte.

Remove target attribute break-sse-dep. Instead, do not fold load into sse partial update instructions unless optimizing for size.

llvm-svn: 91910

llvm-svn: 91908

While converting one of the operands to a memory operand, we need to check if it is Legal and does not result into a cyclic dep.

llvm-svn: 91904

return partial registers. This affected the back-end lowering code some.

Also patch up some places I missed before in the "get" functions.
