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

static inline functions with macros.

llvm-svn: 91973

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

they're available_externally broke VMKit, which was relying on the fact that
functions would only be materialized when they were first called.  We'll have
to wait for http://llvm.org/PR5737 to really fix this.

I also added a test for one of the F->isDeclaration() calls which wasn't
covered by anything else in the test suite.

is finished.

llvm-svn: 91942

argument to runJITOnFunction(), which caused a null pointer dereference at
every call.

Patch by Gianluca Guida!

llvm-svn: 91939

was using "Tmp1" in the first getNode call instead of Node->getOperand(0).

llvm-svn: 91936

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

These checks would often trigger on unreachable statements inserted by
bugpoint, leading it astray.

It would be nice if we could distinguish unreachable blocks from errors.

ARM uses these to indicate predicates.

llvm-svn: 91922

llvm-svn: 91920

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

llvm-svn: 91919

load is needed when we have a small store into a large alloca (at which 
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.

This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete.  Instead of doing this, just don't insert the dead load.

This fixes rdar://6864035

"indirect" operand is not a pointer.

llvm-svn: 91913

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

missing check that an array reference doesn't go past the end of the array,
and remove some redundant checks for in-bound array and vector references
that are no longer needed.

llvm-svn: 91897

by merging all returns in a function into a single one, but simplifycfg 
currently likes to duplicate the return (an unfortunate choice!)

llvm-svn: 91890

instead of stored.  This reduces memdep memory usage, and also eliminates a bunch of
weakvh's.  This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x)
on a different machine than earlier.

llvm-svn: 91885

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

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