Evan Cheng 9ac3631fa3 If the result of a BIT_CONVERT is a v1* vector, it doesn't mean its source is a v1* vector.

Duncan Sands 70424d195a Silence the compiler warning differently. The
original method caused gcc-4.2 to complain.

Nate Begeman f79f52282c Actually scalarize the operand to BIT_CONVERT instead of asking someone to do
something with a v1 type.

Dale Johannesen ce4396bc92 Add CommonLinkage; currently tentative definitions
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

Evan Cheng 1120279ae6 Instead of a vector load, shuffle and then extract an element. Load the element from address with an offset.
pshufd $1, (%rdi), %xmm0
        movd %xmm0, %eax
=>
        movl 4(%rdi), %eax

Dan Gohman 0479aa5c0b Change class' public PassInfo variables to by initialized with the
address of the PassInfo directly instead of calling getPassInfo.
This eliminates a bunch of dynamic initializations of static data.

Also, fold RegisterPassBase into PassInfo, make a bunch of its
data members const, and rearrange some code to initialize data
members in constructors instead of using setter member functions.

several things that were neither in an anonymous namespace nor static
but not intended to be global.

Dale Johannesen 9d29283fc7 Be more aggressive about tail-merging small blocks
if those blocks consist entirely of common instructions;
merging will not add an extra branch in this case.

Bill Wendling 6b8bd513d4 Constify isSourceDefinedByImplicitDef function. Otherwise, just formatting
changes that don't change functionality.

Dale Johannesen c4c4d8e1f7 Further rework of tail merge algorithm. Not quite
semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

Nate Begeman cfcb56091b Add support for vicmp/vfcmp codegen, more legalize support coming.
This is necessary to unbreak the build.

2008-05-12 19:40:03 +00:00
Bill Wendling 70613b84da One real change - don't hoist something that's trivially rematerializable. It's
possible for it to produce worse code than before.

The rest of this patch is code cleanup.

Dale Johannesen cff7df201c Rewrite tail merging algorithm to handle the
case where there are multiple blocks with a large
number of common tail instructions more efficiently
(compile time optimization).

Duncan Sands 9897eee483 Get exception handling working again on 64 bit
Darwin.  This is a hack of course, but it does
at least look at the right thing: gotpcrel means
that this is already an offset, so an explicit
offset is not needed (and wrong).  I think this
is good enough for the moment: Anton is working
on something better.

2008-05-07 22:54:15 +00:00
Duncan Sands e2b0bf43a7 Output correct exception handling and frame info
on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

Evan Cheng 7ca4a67ca1 Yet another nasty spiller bug.
%ecx = op
store %cl<kill>, (addr)
(addr) = op %al

It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below.

Dan Gohman 38dc08f36f Instead of enumerating each opcode that isn't handled that
ComputeMaskedBits handles, just use a 'default:'. This avoids
TargetLowering's list getting out of date with SelectionDAG's.

Chris Lattner d4b2a67cf3 don't randomly miscompile seto/setuo just because we are in
