Revert a tiny bit of r148553 which extended LLVM's function attributes
to 64-bits, and added a new attribute in bit #32. Specifically, remove
this new attribute from the enum used in the C API. It's not yet clear
what the best approach is for exposing these new attributes in the
C API, and several different proposals are on the table. Until then, we
can simply not expose this bit in the API at all.

<< 31" is technically undefined behavior, implementations DTRT here.

values. If folks feel strongly about this I can put the 'U' back in, but

12 years agoSet correct <def,undef> flags when lowering REG_SEQUENCE.
Jakob Stoklund Olesen [Tue, 24 Jan 2012 23:28:42 +0000 (23:28 +0000)]
Set correct <def,undef> flags when lowering REG_SEQUENCE.

A REG_SEQUENCE instruction is lowered into a sequence of partial defs:

  %vreg7:ssub_0<def,undef> = COPY %vreg20:ssub_0
  %vreg7:ssub_1<def> = COPY %vreg2
  %vreg7:ssub_2<def> = COPY %vreg2
  %vreg7:ssub_3<def> = COPY %vreg2

The first def needs an <undef> flag to indicate it is the beginning of
the live range, while the other defs are read-modify-write.  Previously,
we depended on LiveIntervalAnalysis to notice and fix the missing
<def,undef>, but that solution was never robust, it was causing problems
with ProcessImplicitDefs and the lowering of chained REG_SEQUENCE
instructions.

This fixes PR11841.

Revert r148686 (and r148694, a fix to it) due to a serious layering
violation -- MC cannot depend on CodeGen.

Specifically, the MCTargetDesc component of each target is actually
a subcomponent of the MC library. As such, it cannot depend on the
target-independent code generator, because MC itself cannot depend on
the target-independent code generator. This change moved a flag from the
ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in
ARMException.cpp, leaving behind an 'extern' to refer back to it. That
layering order isn't viable givin the constraints outlined above.
Commandline flags are designed to be static specifically to avoid these
types of bugs.

Fixing this is likely going to require some non-trivial refactoring.
