parallel its analogue, Value::value_use_iterator. The operator* method
now returns the user, rather than the use.

Duncan Sands d9374421ea Some binary operations were being treated as
unary operations!  Add support for softening
some additional unary operations like fp_to_sint.

Owen Anderson 54912b3e8d Fix the issues originally addressed in r54070. After thinking about it some more, I realized that the right thing to do
is to have StrongPHIElimination use its knowledge of the PHIs before they're erased to update the intervals appropriate.  This is
both simpler and more accurate than the alternative, which was having LIA figure it out when it renumbered things, plus it's just
the right thing to do!

Owen Anderson 7a45b168ac Revert my previous patch. In retrospect, this is completely the wrong way to fix this problem.
llvm-svn: 54072
2008-07-25 23:06:59 +00:00
Owen Anderson 074f9db2fd Special cases are needed in renumbering when dealing with renumbering after a PHI has been removed. The interval previously defined
by the PHI needs to be extended to the beginning of its basic block, and the intervals that were inputs need to be trimmed to the end 
of their basic blocks.

Owen Anderson 0346aba5c2 In order to avoid reprocessing a register more than once, we need to add it
to the handled set so it will get filtered out in future iterations.

Dan Gohman 685fd8081d Rename the version of CreateRet that's a convenience method for creating
multiple-valued return values, so that the name CreateRet is just for
creating plain ret statements.

llvm-svn: 54053
2008-07-25 20:36:15 +00:00
Owen Anderson c7d53fd331 Make the remapping of interval indices (particularly ending indices) more robust.
This is tricky business, and will probably take a few more iterations to get
the last kinks out of it.

Dan Gohman 394ec3ab5a Disable the new aggressive remat logic introduced in 54000; it causes some

Dan Gohman 9268601d8a Use AliasAnalysis::pointsToConstantMemory in SDISel to avoid unnecessary

Dan Gohman 09b0448dbc Enable rematerialization of constants using AliasAnalysis::pointsToConstantMemory,
and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow
constants to be rematerialized in PIC mode -- the extra indirection is a
complication.

Dan Gohman 5f36a32e7b Put the LICM of constant GlobalVariables, introduced in r53945, under a

Chris Lattner e754764aa9 'Previously, the emacs tablegen mode would highlight constants even if
they appear in words. This would cause things like the "128" in "VR128"
to be highlighted. This patch fixes the highlighting by only recognizing 
constants when they have word breaks around them.'

Dan Gohman fa1211f69b Enable first-class aggregates support.
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.
