Anton Korobeynikov 592638ae05 Allow symbols to start from the digit if target requests it. This allows, e.g. pinning 
variables to specified absolute address. Make use of this feature for MSP430.
This unbreaks PR4776.

Evan Cheng 6ba1931d60 Fix a bug in sdisel switch lowering code. When it updates the phi nodes in switch successor blocks, it can introduce multiple phi operands of the same value from different blocks (and may not be on the predecessor list). 
This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).

John McCall 26a96b0369 Fix a few places where PointerIntPair was using PointerLikeTypeTraits<PointerTy> 
instead of the PtrTraits provided.  Allows PointerIntPair to contain a
PointerUnion safely, as long as the bits add up.

Dan Gohman 36bad00bef Teach ScalarEvolution how to reason about no-wrap flags on loops 
where the induction variable has a non-unit stride, such as {0,+,2}, and
there are expressions such as {1,+,2} inside the loop formed with
or or add nsw operators.

Evan Cheng f56b0482c4 Fix PR4910: Broken logic in coalescer means when a physical register liveness is being shortened, the sub-registers were not. The symptom is the register allocator could not find a free register for this particular test.

 2009-09-16 20:39:11 +00:00
Dan Gohman 0f64d71d99 Add a new pass for doing late hoisting of floating-point and vector 
constants out of loops. These aren't covered by the regular LICM
pass, because in LLVM IR constants don't require separate
instructions. They're not always covered by the MachineLICM pass
either, because it doesn't know how to unfold folded constant-pool
loads. This is somewhat experimental at this point, and off by
default.

Dan Gohman e8d0150398 Now that llc can read .ll files directly, teach it to recognize .ll as 
an extension, so that the default output filename for foo.ll is foo.s,
not foo.ll.s

Kevin Enderby ecd879a2d5 Fixed some problems with the logic of parsing line comments by adding 
isAtStartOfComment and using that instead in two places where a loop
