Chris Lattner 04bf64d43c eliminate the v[if]cmp versions of these tests, now that [if]cmp+sext works.

Chris Lattner dc84b31d94 Change these tests to use [fi]cmp+sext instead of v[fi]cmp. No
functionality change.

Chris Lattner 4ac607332d dag combine sext(setcc) -> vsetcc before legalize. To make this safe,
VSETCC must define all bits, which is different than it was documented
to before.  Since all targets that implement VSETCC already have this
behavior, and we don't optimize based on this, just change the 
documentation.  We now get nice code for vec_compare.ll

Chris Lattner 30220d8f98 implement support for spliting and scalarizing vector setcc's. This
finishes off enough support for vector compares to get the icmp/fcmp
version of 2008-07-23-VSetCC.ll passing.

Chris Lattner 87d4f309f5 verify that the fcmp version of this works just as well as the
vfcmp version.  We actually get better code for this silly testcase.

Chris Lattner edb8407f0c do not try to analyze bitcasts from i64 to <2 x i32> in ComputedMaskedBits. While
we could do this, doing so requires adjusting the demanded mask and the code isn't 
doing that yet.  This fixes PR4495

Evan Cheng 04f72fc955 CommuteChangesDestination() should check if to-be-commuted instruction defines any register. Also teaches the default commuteInstruction() to commute instruction without definitions (e.g. X86::test / ARM::tsp).

Evan Cheng 2a5efe14a7 Remove special handling of implicit_def. Fix a couple more bugs in liveintervalanalysis and coalescer handling of implicit_def.
Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def.

Evan Cheng d379e896ff Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details.

Rafael Espindola 317fd045e2 Fix PR4485.
Avoid unnecessary duplication of operand 0 of X86::FpSET_ST0_80. This duplication would
cause one register to remain on the stack at the function return.

Evan Cheng dcf1f59305 Temporarily restore the scavenger implicit_def checking code. MachineOperand isUndef mark is not being put on implicit_def of physical registers (created for parameter passing, etc.).
llvm-svn: 74519
2009-06-30 09:19:42 +00:00
Evan Cheng 0dc101b897 Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them.
The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.

This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.
