It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.
I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

Change getFrameMoves to return a const reference.2013-05-11T02:38:11ZRafael Espindolarafael.espindola@gmail.com2013-05-11T02:38:11Zurn:sha1:d84ccfaf50c7843f31ffc74a8a8e33f779453d6e
To add a frame now there is a dedicated addFrameMove which also takes
care of constructing the move itself.

[SystemZ] Fix InitMCCodeGenInfo call2013-05-07T12:56:31ZRichard Sandifordrsandifo@linux.vnet.ibm.com2013-05-07T12:56:31Zurn:sha1:7a1ead46fb629839e5ce25574246ee743ab8b54f
createSystemZMCCodeGenInfo was not passing the optimization level to
InitMCCodeGenInfo(), so -O0 would be ignored. Fixes DebugInfo/namespace.ll
after the changes in r181271.

[SystemZ] Add back end2013-05-06T16:15:19ZUlrich Weigandulrich.weigand@de.ibm.com2013-05-06T16:15:19Zurn:sha1:1d09d56fe1e3f3faadd4bf4ccf3e585ddb3c3b07
This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target. Note that at this point, the target
cannot yet be built since the configure bits are missing. Those
will be provided shortly by a follow-on patch.
This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov. Thanks to all reviewers!

Ban rematerializable instructions with side effects.2011-10-14T01:00:49ZJakob Stoklund Olesenstoklund@2pi.dk2011-10-14T01:00:49Zurn:sha1:ccbe603869681aa71b4140e3bf4b4459caf60622
TableGen infers unmodeled side effects on instructions without a
pattern. Fix some instruction definitions where that was overlooked.
Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

Add codegen support for vector select (in the IR this means a select2011-09-06T19:07:46ZDuncan Sandsbaldrick@free.fr2011-09-06T19:07:46Zurn:sha1:28b77e968d2b01fc9da724762bd8ddcd80650e32
with a vector condition); such selects become VSELECT codegen nodes.
This patch also removes VSETCC codegen nodes, unifying them with SETCC
nodes (codegen was actually often using SETCC for vector SETCC already).
This ensures that various DAG combiner optimizations kick in for vector
comparisons. Passes dragonegg bootstrap with no testsuite regressions
(nightly testsuite as well as "make check-all"). Patch mostly by
Nadav Rotem.
