is just a trivial wrapper around "ClassifyGlobalReference", which
stole a ton of logic from LowerGlobalAddress.

to use isGlobalStubReference instead of GVRequiresExtraLoad
(which should really be part of isel).

llvm-svn: 75234

MachineOperand is a reference to a stub, not a reference to the
global variable itself.  Look no context needed!

more complex and slow than just directly testing what we care about.

split its handling out to PCRelGVRequiresExtraLoad, and simplify code
based on this.

We don't need separate thumb1 instructions tADDSi3 etc. for addc and subc. The "normal" version always modify condition register CPSR so we should just use def : pat to match to the same instructions.

and replace the 'clang-cc' option '-analyzer-store=basic-new-cast' with
'-analyzer-store=basic-old-cast'. We'll keep the old CastRegion implementation
around for a little while for regression testing.

Fix #include specification.

is still mutable. My experiments show this reduces the amount of times we
compute a full tree digest by over 50% on very small cases, and potentially much
larger on others.

Use getAsmName() method instead of accessing AsmName field directly.

Redesign this to avoid standard stream classes.  This stream class
provides pretty -printing of comments and other such things in asm
files.

This is part of the fix for pr4521.

llvm-svn: 75201

This started as a small change, I swear.  Unfortunately, lots of things call the [I|F]CmpInst constructors.  Who knew!?

llvm-svn: 75200

Add some hooks that a redesigned AsmStream needs to do its job.  These
allow derived classes to examine the stream buffer before it's flushed.

merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

Initial support for load / store multiple opt pass Thumb2 support (post-allocation only). It's kind of there, but not quite. I'll return to this later.

is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

Fix ldrd / strd address mode matching code. It allows for +/- 8 bit offset. Also change the printer to make the scale 4 explicit.

Note, we are not yet generating these instructions.
