Chris Lattner c482a9e31a Implement Transforms/InstCombine/bswap.ll, turning common shift/and/or bswap 
idioms into bswap intrinsics.

llvm-svn: 28803
 2006-06-15 19:07:26 +00:00
Chris Lattner c09a6ea07a new testcase, instcombine should turn these into llvm.bswap intrinsics.

Chris Lattner 3743bd84cd Fix building on case-sensitive file systems, grr :)

Reid Spencer aba6398f8b Actually add instructions to the list of defined values so it gets 
recognized as such!  This prevents the CppWriter from treating every
operand as a forward reference and making a mess of the output.

Jim Laskey dce07568f2 Alignment of globals has not been quite right. Needed to drop the pointer type 
to get the alignment of the element type.

Evan Cheng 66f0e09313 Vector extract / insert index operand should have ptr type. 
llvm-svn: 28798
 2006-06-15 08:19:05 +00:00
Evan Cheng 94bb93f8f7 Type of extract_element index operand should be iPTR. 
llvm-svn: 28797
 2006-06-15 08:18:06 +00:00
Evan Cheng de7156f12c Type of vector extract / insert index operand should be iPTR. 
llvm-svn: 28796
 2006-06-15 08:14:54 +00:00
Evan Cheng ef9e07d3f0 Consistency. EXTRACT_ELEMENT index operand should have ptr type.

Evan Cheng df63179d95 Assert. Rather than silently stop printing. 
llvm-svn: 28794
 2006-06-15 08:10:56 +00:00
Evan Cheng 1dfdffb9b2 Avoid undesirable behavior when assert is not enabled.

 2006-06-15 08:10:27 +00:00
Evan Cheng 55772ccfd6 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

 2006-06-15 07:22:16 +00:00
Evan Cheng 5d038cf802 Allow more use of iPTR in patterns. 
llvm-svn: 28790
 2006-06-15 00:16:37 +00:00
Evan Cheng c8734381ac X86 call instructions can take variable number of operands. Parameters of 
vector types are passed via XMM registers.

llvm-svn: 28789
 2006-06-14 22:24:55 +00:00
Evan Cheng ff7c28dfdd Added support for variable_ops.

Chris Lattner 0c4f5a655a Fix Transforms/LoopUnswitch/2006-06-13-SingleEntryPHI.ll, a loop unswitch 
bug exposed by the recent lcssa work.

Chris Lattner d3c7db5fa8 new testcase, distilled from povray

Owen Anderson 4e744af80c When asked not to delete useless PHIs, really don't delete them, no matter how 
redundant they are.

Chris Lattner e3abb14503 Use the PotDoms map to memoize 'dominating value' lookup. With this patch, 
LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes
39s instead of 289s. :)

 2006-06-13 20:50:09 +00:00
Owen Anderson 7e428625c9 Update isLCSSAForm to handle PHI nodes specially for live-out detection. This 
is the same as the recent patch to LCSSA.cpp.

 2006-06-13 20:45:22 +00:00
Andrew Lenharth 7c69df968c I am sure I had commited this workaround before. Perhaps soon I should sort it all out

Owen Anderson 3f8ff0449a Fix a bug that was causing major slowdowns in povray. This was due to LCSSA 
not handling PHI nodes correctly when determining if a value was live-out.

This patch reduces the number of detected live-out variables in the testcase
from 6565 to 485.

llvm-svn: 28771

Andrew Lenharth f570feeae3 It really helps to be returning to the correct place

Chris Lattner c5bb8ab1d5 Port some bugfixes in shift handling from SimplifyDemandedBits over to 
ComputeMaskedBits.  DemandedMasks and KnownZero/One masks should never have
bits set out of the range of the base datatype.

Jim Laskey a48a176321 My original test case was bogus. Reverting to crasher case.

Jim Laskey 8cac9cd5f6 TargetLowering::ComputeMaskedBits was not clearing reciprocal bits on shifts.

Chris Lattner 20ec1654b1 Teach bugpoint to kill optimization passes that run over the timeout limit, 
which allows it to debug optimizer infinite loops.  This patch is contributed
by Nick Lewycky, thanks!

Chris Lattner ac59ab515a Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register 
allocated, thus live across the save/reload.  This fixes

Owen Anderson 0ac336965e Fix for 2006-06-26-MultipleExitsSingleBlock. 
If a single exit block has multiple predecessors within the loop, it will
appear in the exit blocks list more than once.  LCSSA needs to take that into
account so that it doesn't double process that exit block.
