fp_round's produced by getCopyFromParts should always be exact, because
...
they are produced by calls (which are known exact) and by cross block copies
which are known to be produced by extends.
This improves:
define double @test2() {
%tmp85 = call double asm sideeffect "fld0", "={st(0)}"()
ret double %tmp85
}
from:
_test2:
subl $20, %esp
# InlineAsm Start
fld0
# InlineAsm End
fstpl 8(%esp)
movsd 8(%esp), %xmm0
movsd %xmm0, (%esp)
fldl (%esp)
addl $20, %esp
#FP_REG_KILL
ret
to:
_test2:
# InlineAsm Start

# InlineAsm End
#FP_REG_KILL

Fix two problems in SelectionDAGLegalize::ExpandBUILD_VECTOR's handling
...
of BUILD_VECTORS that only have two unique elements:
1. The previous code was nondeterminstic, because it walked a map in
SDOperand order, which isn't determinstic.
2. The previous code didn't handle the case when one element was undef
very well. Now we ensure that the generated shuffle mask has the
undef vector on the RHS (instead of potentially being on the LHS)
and that any elements that refer to it are themselves undef. This
allows us to compile CodeGen/X86/vec_set-9.ll into:
_test3:
movd %rdi, %xmm0
punpcklqdq %xmm0, %xmm0

_test3:

For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.

- Instead of restarting the processing of an instruction if we remove an

isn't incremented.

This is the initial check-in for adding register scavenging to PPC. (Currently,
...
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.

Go through the machine instruction's operands to make sure that we're not

marking both a super- and sub-register as "killed". This removes implicit uses
that are marked as "killed".

Multiple instructions can be inserted when eliminating frame indexes. We need

the register scavenger to process all of those new instructions instead of just
the last one inserted.
