llvm-svn: 27998
 2006-04-27 21:40:57 +00:00
Chris Lattner b6cb64b7e6 Add support for inserting undef into a vector. This implements 
Transforms/InstCombine/vec_insert_to_shuffle.ll

llvm-svn: 27997
 2006-04-27 21:14:21 +00:00
Chris Lattner 51fecaa8b3 This should turn into one vector shuffle instruction. 
llvm-svn: 27996
 2006-04-27 21:13:58 +00:00
Evan Cheng f4f3f0d25f Make x86 isel lowering produce tailcall nodes. They are match to normal calls 
for now.

Patch contributed by Alexander Friedman.

Evan Cheng ec04a37edd A couple of new entries. 
llvm-svn: 27993
 2006-04-27 08:31:33 +00:00
Evan Cheng 89001ad729 Support for passing 128-bit vector arguments via XMM registers.

 2006-04-27 08:31:10 +00:00
Evan Cheng 3784f3c57c Insert a VBIT_CONVERT between a FORMAL_ARGUMENT node and its vector uses 
(VAND, VADD, etc.). Legalizer will assert otherwise.

Reid Spencer bb0be98fed For PR747: 
If we fail to find a required program, simply set that program to echo
out something that tells the user the situation. That is, instead of just
"true runtest" we now get "echo 'Skipped: runtest not found'".

Evan Cheng a0374e1bed Oops

Chris Lattner fb1ab10337 new testcase 
llvm-svn: 27986
 2006-04-27 05:00:43 +00:00
Evan Cheng 48940d16b2 - Clean up formal argument lowering code. Prepare for vector pass by value work. 
- Fixed vararg support.

 2006-04-27 01:32:22 +00:00
Chris Lattner f98b4aa2e7 Fix some nondeterminstic behavior in the mem2reg pass that (in addition to 
nondeterminism being bad) could cause some trivial missed optimizations (dead
phi nodes being left around for later passes to clean up).

With this, llvm-gcc4 now bootstraps and correctly compares.  I don't know
why I never tried to do it before... :)

Jeff Cohen 027fbc2a6a Actually, semantical doesn't appear to be a word. 
llvm-svn: 27983
 2006-04-26 21:03:17 +00:00
Chris Lattner e8cbdbf314 Implement Transforms/IndVarsSimplify/complex-scev.ll, a case where we didn't 
recognize some simple affine IV's.

Reid Spencer 9aa244ed16 Add some notes about the current state of source (front end) languages 
so we can point to them on llvm-dev.

Nate Begeman 4530327c04 Keep the stack from on darwin 16-byte aligned. This fixes many JIT 
failres.

llvm-svn: 27973
 2006-04-25 20:54:26 +00:00
Evan Cheng a9467aab0a Separate LowerOperation() into multiple functions, one per opcode. 
llvm-svn: 27972
 2006-04-25 20:13:52 +00:00
Andrew Lenharth 3c775bcd86 slightly more useful error message 
llvm-svn: 27971
 2006-04-25 19:33:41 +00:00
Andrew Lenharth f5a713d273 better c99 struct handling 
llvm-svn: 27970
 2006-04-25 19:33:23 +00:00
Andrew Lenharth a3f7583408 another c99 style problem

Nate Begeman 318bb96f9e No functionality changes, but cleaner code with correct comments. 
llvm-svn: 27966
 2006-04-25 04:45:59 +00:00
Evan Cheng fb46b2bf5d Explicitly specify result type for def : Pat<> patterns (if it produces a vector 
result). Otherwise tblgen will pick the default (v16i8 for 128-bit vector).

llvm-svn: 27965
 2006-04-25 00:50:01 +00:00
Evan Cheng 25b09295f8 Added X86 SSE2 intrinsics which can be represented as vector_shuffles. This is 
a temporary workaround for the 2-wide vector_shuffle problem (i.e. its mask
would have type v2i32 which is not legal).

llvm-svn: 27964
 2006-04-24 23:34:56 +00:00
Evan Cheng d03631ee76 Add a new entry. 
llvm-svn: 27963

Evan Cheng 347a5a7afa Added a movq test case. 
llvm-svn: 27962
 2006-04-24 23:03:22 +00:00
Evan Cheng 5c2bfb069e Special case handling two wide build_vector(0, x). 
llvm-svn: 27961
 2006-04-24 22:58:52 +00:00
Evan Cheng 63bd4d3730 Some missing movlps, movhps, movlpd, and movhpd patterns. 
llvm-svn: 27960
 2006-04-24 21:58:20 +00:00
Evan Cheng b0461080e4 A little bit more build_vector enhancement for v8i16 cases. 
llvm-svn: 27959
 2006-04-24 18:01:45 +00:00
Evan Cheng 2f9b0bcbd5 Remove a completed entry. 
llvm-svn: 27958
 2006-04-24 17:38:16 +00:00
Chris Lattner 3046d54df2 Suggest looking at the SPARC backend. How weird is that?? :) 
llvm-svn: 27957

Evan Cheng 60bb622e4d Added addJumpTableIndex 
llvm-svn: 27956
 2006-04-24 06:42:15 +00:00
Evan Cheng ab0ee6340c MakeMIInst() should handle jump table index operands.

Chris Lattner f110527a29 Add a note

 2006-04-23 19:47:09 +00:00
Evan Cheng b4f31dd1a8 MOVL shuffle (i.e. movd or movss / movsd from memory) of undef, V2 == V2 
llvm-svn: 27953
 2006-04-23 06:35:19 +00:00
Nate Begeman 866b4b4d45 Fix the updating of the machine CFG when a PHI node was in a successor of 
the jump table's range check block.  This re-enables 100% dense jump tables
by default on PPC & x86

llvm-svn: 27952
 2006-04-23 06:26:20 +00:00
Jeff Cohen 7a2a972ba9 Keep Visual Studio informed. 
llvm-svn: 27951
 2006-04-23 04:37:08 +00:00
Nate Begeman 3e04bb482b Code cleanup associated with jump tables, thanks to Chris for noticing 
these.

llvm-svn: 27950
 2006-04-22 23:52:35 +00:00
Nate Begeman ecb1dafd3d Turn of jump tables for a bit, there are still some issues to work out with 
updating the machine CFG.

Nate Begeman 9f0b13c885 Optimized stores to the constant pool, while cool, are unnecessary.
