add-hoc value-range analysis functionality.

done in ClassifyGlobalReference instead of reconstructing the info
awkwardly.

llvm-svn: 75240

PIC-base to be added in.

llvm-svn: 75238

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

llvm-svn: 75237

llvm-svn: 75236

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!

llvm-svn: 75233

llvm-svn: 75232

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

llvm-svn: 75231

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.

llvm-svn: 75206

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

llvm-svn: 75205

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

llvm-svn: 75202

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.

llvm-svn: 75192

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.

llvm-svn: 75191

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)!!!

llvm-svn: 75183

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.

llvm-svn: 75181

what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.
