Bob Wilson 08882be86c Remove DAG combiner patch to fold vector splats. Instcombiner does it now. 
llvm-svn: 117720
 2010-10-29 22:03:02 +00:00
Bob Wilson cb11b48e7a Make instcombine a little more aggressive in combining vector shuffles. 
Allow splats even if they don't match either of the original shuffles,
possibly due to undef entries in the shuffles masks.  Radar 8597790.
Also fix some 80-column violations.

Caroline Tice 20ad3c40f4 Add the ability to disable individual log categories, rather 
than just the entire log channel.

Add checks, where appropriate, to make sure a log channel/category has 
not been disabled before attempting to write to it.

Owen Anderson 374e1464ae Give up on doing in-line instruction simplification during correlated value propagation. Instruction simplification 
needs to be guaranteed never to be run on an unreachable block.  However, earlier block simplifications may have
changed the CFG to make block that were reachable when we began our iteration unreachable by the time we try to
simplify them. (Note that this also means that our depth-first iterators were potentially being invalidated).

This should not have a large impact on code quality, since later runs of instcombine should pick up these simplifications.
Fixes PR8506.

handle it in the asm lowering.

Johnny Chen 8ceb8ba2fb The r117616 check in broken these two test cases: 
1. FoundationDisassembleTestCase.test_simple_disasm_with_dsym; and
2. FoundationDisassembleTestCase.test_simple_disasm_with_dwarf

the reason being the test was issuing 'disassemble' command to disassemble the current
frame function when stopped.  The 'disassemble' command worked previously but it was a
result of bad option specification.

Fix the disassemble command so that it will require 'disassemble -f' for disassembly of
the current frame function.

Evan Cheng 6c1414f9c2 Avoiding overly aggressive latency scheduling. If the two nodes share an 
operand and one of them has a single use that is a live out copy, favor the
one that is live out. Otherwise it will be difficult to eliminate the copy
if the instruction is a loop induction variable update. e.g.

BB:
sub r1, r3, #1
str r0, [r2, r3]
mov r3, r1
cmp
bne BB

=>

BB:
str r0, [r2, r3]
sub r3, r3, #1
cmp
bne BB

This fixed the recent 256.bzip2 regression.

Jakob Stoklund Olesen dff6a6e4f1 Teach ConnectedVNInfoEqClasses::Classify to deal with unused values. 
We don't want unused values forming their own equivalence classes, so we lump
them all together in one class, and then merge them with the class of the last
used value.
