the array fields in these structs.

Bill Wendling 2d3c490026 It's possible that a flag is added to the SDNode that points back to the
original SDNode. This is badness. Also, this function allows one SDNode to point
multiple flags to another SDNode. Badness as well.

Jakob Stoklund Olesen 2b87d44c5d Don't return a std::vector in the Spiller interface, but take a reference to a
vector instead. This avoids needless copying and allocation.

Jakob Stoklund Olesen 9b659142a6 Remove the now unused LiveIntervals::getVNInfoSourceReg().
This method was always a bit too simplistic for the real world. It didn't really
deal with subregisters and such.

Dale Johannesen 5ad5226c58 Disallow matching "i" constraint to symbol addresses when
address requires a register or secondary load to compute
(most PIC modes).  This improves "g" constraint handling.  8015842.

The test from 2007 is attempting to test the fix for PR1761,
but since -relocation-model=static doesn't work on Darwin
x86-64, it was not testing what it was supposed to be testing
and was passing erroneously.  Fixed to use Linux x86-64.

This code path has never really been used, and we are going to be handling
spilling through the Spiller interface in the future.

Bill Wendling 3f0e992af1 Loosen up the requirements in the Horrible Hack(tm) to include all selectors
which don't have a catch-all associated with them not just clean-ups. This fixes

of my change r105902.

Jakob Stoklund Olesen 45230239e4 Replace a big gob of old coalescer logic with the new CoalescerPair class.
CoalescerPair can determine if a copy can be coalesced, and which register gets
merged away. The old logic in SimpleRegisterCoalescing had evolved into
something a bit too convoluted.

This second attempt fixes some crashes that only occurred Linux.

Jakob Stoklund Olesen a612d7c012 Print the LSBs of a SlotIndex symbolically using letters referring to the
[L]oad, [u]se, [d]ef, or [S]tore slots.

This makes it easier to see if two indices refer to the same instruction,
avoiding mental mod 4 calculations.

Dan Gohman 47ddf76d89 Teach getExactSDiv to evaluate x/1 to x up front, as it's a common
enough special case, and it theoretically allows more folding because
it works even when x is unanalyzable.

Bob Wilson 279e55fb2e PR7458: Try commuting Thumb2 instruction operands to put them into 2-address
form so they can be narrowed to 16-bit instructions.

Bob Wilson 1cfe454c87 Edit and clarify comments for TargetInstrInfo methods:
None of the existing implementations of commuteInstruction create new
instructions unless the NewMI parameter is true, but the comment had
implied otherwise.

findCommutedOpIndices returns false, not true, when it doesn't know
how to commute the instruction.

Jakob Stoklund Olesen 53ccab7d1c Verify that VNI kills are pointing to existing instructions.
In this case it is essential that the kill is real because the spiller will

llvm-svn: 106749
2010-06-24 15:24:03 +00:00
Dan Gohman df6b33e778 Eliminate the first have of the optimization which eliminates BRCOND
when the condition is constant. This optimization shouldn't be
necessary, because codegen shouldn't be able to find dead control
paths that the IR-level optimizer can't find. And it's undesirable,
because it encourages bugpoint to leave "br i1 false" branches
in its output. And it wasn't updating the CFG.

I updated all the tests I could, but some tests are too reduced
and I wasn't able to meaningfully preserve them.
