llvm-svn: 75012
 2009-07-08 16:15:06 +00:00
David Goodwin af7451b674 Checkpoint Thumb2 Instr info work. Generalized base code so that it can be shared between ARM and Thumb2. Not yet activated because register information must be generalized first. 
llvm-svn: 75010
 2009-07-08 16:09:28 +00:00
Nick Lewycky a21d3daadc Remove the vicmp and vfcmp instructions. Because we never had a release with 
these instructions, no autoupgrade or backwards compatibility support is
provided.

 2009-07-08 03:04:38 +00:00
Chris Lattner 04bf64d43c eliminate the v[if]cmp versions of these tests, now that [if]cmp+sext works. 
llvm-svn: 74980
 2009-07-08 00:49:35 +00:00
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

llvm-svn: 74978
 2009-07-08 00:31:33 +00:00
Chris Lattner fc74e8241a add support for legalizing an icmp where the result is illegal (4xi1) but 
the input is legal (4 x i32)

llvm-svn: 74964
 2009-07-07 23:03:54 +00:00
Chris Lattner cbbf747b7b add a trivial test that vector compares work. 
llvm-svn: 74963
 2009-07-07 22:51:09 +00:00
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.

llvm-svn: 74961
 2009-07-07 22:47:46 +00:00
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.

Stuart Hastings e1cd1b5d2a Mark this test as Darwin only. Patch by Bill Wendling. 
llvm-svn: 74829
 2009-07-06 15:36:23 +00:00
Nick Lewycky 3292908132 When comparing constants, consider a less wide constant to be "less complex" 
than a wider one, before trying to compare their contents which will crash
if their sizes are different.

llvm-svn: 74792

Evan Cheng 8ecd7eb3f7 Sign extending pre/post indexed loads. 
llvm-svn: 74736
 2009-07-02 23:16:11 +00:00
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

llvm-svn: 74699

Evan Cheng 84c6cda2ef Thumb2 pre/post indexed loads.

Chris Lattner 87bb642676 @GOTPCREL is also rip-relative. Fix fast-isel to do the right thing. 
This fixes an llvm-gcc bootstrap problem I introduced.

llvm-svn: 74691
 2009-07-02 04:22:01 +00:00
Chris Lattner d1c5951615 Fix yet-another bug I introduced into fastisel, this time handling 
constant pool references that weren't getting properly rip-relative.

Devang Patel 461f2bdcbe new test case 
llvm-svn: 74633
 2009-07-01 19:40:59 +00:00
Devang Patel 39e64d452a Support stand alone metadata syntax. 
!0 = constant metadata !{i32 21, i32 22}
@llvm.blah = constant metadata !{i32 1000, i16 200, metadata !0}

llvm-svn: 74630
 2009-07-01 19:21:12 +00:00
Chris Lattner 1f50b61329 Fix codegen for references to available_externally symbols. This fixes 
PR4482.

llvm-svn: 74613

Stuart Hastings 67a2b76774 Insure that __block_holder_tmp is allocated on the stack when a byref 
variable is present.

llvm-svn: 74610
 2009-07-01 15:40:10 +00:00
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). 
llvm-svn: 74602
 2009-07-01 08:29:08 +00:00
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.

llvm-svn: 74601
 2009-07-01 08:19:36 +00:00
Chris Lattner f95fa1b721 Fix some fast-isel problems selecting global variable addressing in 
pic mode.

llvm-svn: 74582
 2009-07-01 03:27:19 +00:00
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. 
llvm-svn: 74580
 2009-07-01 01:59:31 +00:00
David Goodwin 86c7e20ca6 Add PIC load and store patterns for Thumb-2. 
llvm-svn: 74577
 2009-07-01 00:01:13 +00:00
Daniel Dunbar 8561b6aea0 llvm-mc: Symbols in a relocatable expression of the (a - b + cst) form are 
allowed to be undefined when the expression is seen, we cannot enforce the
same-section requirement until the entire assembly file has been seen.

llvm-svn: 74565
 2009-06-30 22:49:27 +00:00
David Goodwin d0890a2bad Add thumb-2 store word, halfword, and byte. 
llvm-svn: 74555

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.

llvm-svn: 74534
 2009-06-30 16:40:03 +00:00
Rafael Espindola bd971ffcc6 Fix PR4484. 
This was caused by me confounding FP0 and ST(0).
