John McCall 659a337c74 Apply attributes to explicit specializations. Specializations which 
don't provide their own explicit visibility attributes should get them
from the template.  Fixes rdar://problem/8778497.

Jakob Stoklund Olesen 3b2966dc7d Teach the inline spiller to attempt folding a load instruction into its single 
use before rematerializing the load.

This allows us to produce:

    addps	LCPI0_1(%rip), %xmm2

Instead of:

    movaps	LCPI0_1(%rip), %xmm3
    addps	%xmm3, %xmm2

Saving a register and an instruction. The standard spiller already knows how to
do this.

Bill Wendling 429bb1e2cc r120333 changed the opcode for the Thumb1 stuff from ARM::tMOVr to 
ARM::tMOVgpr2gpr. But this check didn't change. As a result, we were getting
misaligned references to the jump table from an ADR instruction.

There is a test case, but unfortunately it's sensitive to random code changes.

Jakob Stoklund Olesen 7971a3eaff Check that the register is live-in to the loop header before inserting copies in 
the loop predecessors.

The register can be live-out from a predecessor without being live-in to the
loop header if there is a critical edge from the predecessor.

Bill Wendling 3fff1fd49b During local stack slot allocation, the materializeFrameBaseRegister function 
may be called. If the entry block is empty, the insertion point iterator will be
the "end()" value. Calling ->getParent() on it (among others) causes problems.

Modify materializeFrameBaseRegister to take the machine basic block and insert
the frame base register at the beginning of that block. (It's very similar to
what the code does all ready. The only difference is that it will always insert
at the beginning of the entry block instead of after a previous materialization
of the frame base register. I doubt that that matters here.)

monotonic keys.

llvm-svn: 122093
 2010-12-17 22:07:54 +00:00
Jakob Stoklund Olesen 54912ed921 It is allowed to call IntervalMap::const_iterator::advanceTo() with a key that 
moves the iterator to end(), and it is valid to call it on end().

That means it is valid to call advanceTo() with any monotonic key sequence.

Owen Anderson 79855298b9 Thumb's forced-PC-alignment requirement applies to the _total_ displacement, not just to the fragment relative 
portion.  While the fragment boundary is usually already aligned, it is possible for it not to be, which 
would lead to a non-aligned final displacement.
