Dan Gohman a209503467 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

llvm-svn: 111941
 2010-08-24 18:50:07 +00:00
Dan Gohman 6901283544 MapValue support for MDNodes. This is similar to r109117, except 
that it avoids a lot of unnecessary cloning by avoiding remapping
MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.

llvm-svn: 111922
 2010-08-24 17:10:10 +00:00
Nick Lewycky 7bc0443f2b Revert this because we can't clone cyclic MDNodes which are creating during a 
build of llvm-gcc.

llvm-svn: 109355
 2010-07-24 20:54:02 +00:00
Nick Lewycky 14b69d59dd Whether function-local or not, a MDNode may reference a Function in which case 
it needs to be mapped to refer to the function in the new module, not the old
one. Fixes PR7700.

Devang Patel 5fa3813329 Speculatively revert 109117 
llvm-svn: 109132
 2010-07-22 18:44:00 +00:00
Devang Patel fac440cfb6 Map MDNode correctly. 
A non function local MDNode can have an operand which is cloned by MapValue(). 

llvm-svn: 109117
 2010-07-22 16:35:00 +00:00
Devang Patel cefe3831b7 MDString is already checked earlier. 
llvm-svn: 107516
 2010-07-02 21:13:23 +00:00
Devang Patel b8f11de105 Cosmetic change. 
Do not use "ValueMap" as a name for a local variable or an argument.

 2010-06-23 23:55:51 +00:00
Devang Patel 9ad629367d Revert 106592 for now. It causes clang-selfhost build failure. 
llvm-svn: 106598
 2010-06-22 23:29:55 +00:00
Devang Patel 87f75f75be If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata. 
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

 Checking to see if we can delete global inits: Unknown constant!

Devang Patel b195eb4acf Do not rely on DenseMap slot which can be easily invalidated when DenseMap grows. 
llvm-svn: 106528
 2010-06-22 05:16:56 +00:00
Devang Patel 2176643241 Rename ValueMapTy as ValueToValueMapTy to clearly indicate that this has no replationship with ADT/ValueMap. 
llvm-svn: 101950
 2010-04-20 22:24:18 +00:00
Devang Patel 382b969647 There is no need to install ValueMapper.h header.

Victor Hernandez 2b17e2a452 Avoid extra calls to MD->getNumOperands() 
llvm-svn: 94618
 2010-01-26 23:29:09 +00:00
Chris Lattner 24716b6c63 It turns out that this #include is needed because otherwise 
ValueMapper.cpp ends up calling an out of line 
__ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
determines arbitrarily to use the one in libipo.  This sucks, but
keeping the #include is a reasonable workaround.

llvm-svn: 94103
 2010-01-21 21:29:25 +00:00
Chris Lattner 9889b4be04 unbreak the build, apparently without this transformutils starts depending on libipa?

llvm-svn: 93979
 2010-01-20 05:49:59 +00:00
Devang Patel 696cb8d410 While mapping llvm.dbg.declare intrinsic manually map its operand, if possible, 
because it points to an alloca instruction through metadata.

Chris Lattner aa99c94e2a Revert 85678/85680. The decision is to stay with the current form of 
indirectbr, thus we don't need "blockaddr(@func, null)".  Eliminate it
for simplicity.

llvm-svn: 85699

Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

llvm-svn: 75640
 2009-07-14 16:55:14 +00:00
Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Running the inliner on 252.eon used to take 48.4763s, now it takes 14.4148s.

In release mode, it went from taking 25.8741s to taking 11.5712s.
