Chris Lattner 9b7d99eb76 The phi translated pointer can be computed when returning a partially cached result 
instead of stored.  This reduces memdep memory usage, and also eliminates a bunch of
weakvh's.  This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x)
on a different machine than earlier.

llvm-svn: 91885
 2009-12-22 04:25:02 +00:00
Chris Lattner 2ee6787c1b avoid calling extractMallocCall when it's obvious we don't have 
a call.  This speeds up memdep ~1.5%

llvm-svn: 91869
 2009-12-22 01:00:32 +00:00
Chris Lattner 25bf6f8946 fix an overly conservative caching issue that caused memdep to 
cache a pointer as being unavailable due to phi trans in the
wrong place.  This would cause later queries to fail even when
they didn't involve phi trans.

llvm-svn: 91742

llvm-svn: 91729
 2009-12-18 23:42:08 +00:00
Dan Gohman 7db230f5c9 Make this comment more precise. 
llvm-svn: 91722
 2009-12-18 23:18:03 +00:00
Dan Gohman 51f13056bd Revert this use of NUW/NSW also. Overflow-undefined multiplication isn't 
associative either.

llvm-svn: 91701
 2009-12-18 18:45:31 +00:00
Dan Gohman 7a2dab8826 Revert this use of NSW; this one isn't actually safe. NSW addition 
is not reassociative.

llvm-svn: 91667
 2009-12-18 03:57:04 +00:00
Dan Gohman 916fec41fb Delete an unused variable. 
llvm-svn: 91659
 2009-12-18 02:14:37 +00:00
Dan Gohman b256ccfbe5 Preserve NSW information in more places. 
llvm-svn: 91656
 2009-12-18 02:09:29 +00:00
Dan Gohman 18fa5686f6 Add Loop contains utility methods for testing whether a loop 
contains another loop, or an instruction. The loop form is
substantially more efficient on large loops than the typical
code it replaces.

Dan Gohman cb0efecd33 Whitespace cleanups. 
llvm-svn: 91651
 2009-12-18 01:14:11 +00:00
Dan Gohman 92c3696524 Reapply LoopStrengthReduce and IVUsers cleanups, excluding the part 
of 91296 that caused trouble -- the Processed list needs to be
preserved for the livetime of the pass, as AddUsersIfInteresting
is called from other passes.

llvm-svn: 91641
 2009-12-18 00:06:20 +00:00
Evan Cheng 090ac0865a Revert 91280-91283, 91286-91289, 91291, 91293, 91295-91296. It apparently introduced a non-deterministic behavior in the optimizer somewhere.

 2009-12-17 09:39:49 +00:00
Chris Lattner a3aef788ec Fix GetConstantStringInfo to not look into MDString (it works on 
real data, not metadata) and fix DbgInfoPrinter to not abuse
GetConstantStringInfo.

Devang Patel 1f4690c624 Add support to emit debug info for C++ namespaces.

Chris Lattner 45d040bd85 Remove isPod() from DenseMapInfo, splitting it out to its own 
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

 2009-12-15 07:26:43 +00:00
John McCall 4ea24f19f5 You can't use typedefs to declare template member specializations, and 
clang enforces it.

llvm-svn: 91397
 2009-12-15 02:35:24 +00:00
Dan Gohman 2a07fd94f1 Clear the Processed set when it is no longer used, and clear the 
IVUses list in releaseMemory().

llvm-svn: 91296
 2009-12-14 17:35:17 +00:00
Dan Gohman fbeec7270c Fix a thinko; isNotAlreadyContainedIn had a built-in negative, so the 
condition was inverted when the code was converted to contains().

llvm-svn: 91295
 2009-12-14 17:31:01 +00:00
Dan Gohman 57eb6cda7a Drop Loop::isNotAlreadyContainedIn in favor of Loop::contains. The 
former was just exposing a LoopInfoBase implementation detail.

llvm-svn: 91286
 2009-12-14 17:06:50 +00:00
Dan Gohman 84ba039cf2 Make getUniqueExitBlocks's precondition assert more precise, to 
avoid spurious failures. This fixes PR5758.

llvm-svn: 91147
 2009-12-11 20:05:23 +00:00
Dan Gohman 220b196c94 Reuse the Threshold value to size these containers because it's 
currently somewhat convenient for them to have the same value.

llvm-svn: 90980
 2009-12-09 18:48:53 +00:00
Chris Lattner 9f9010ef47 Add a minor optimization: if we haven't changed the operands of an 
add, there is no need to scan the world to find the same add again.
This invalidates the previous testcase, which wasn't wonderful anyway,
because it needed a run of instcombine to permute the use-lists in 
just the right way to before GVN was run (so it was really fragile).
Not a big loss.
