Chris Lattner 4565ef5b65 reimplement Constant::ContainsRelocations as 
Constant::getRelocationInfo(), which has a much simpler
to use API.  It still should not be part of libvmcore, but
is better than it was.  Also teach it to be smart about 
hidden visibility.

Dan Gohman 33a3fd0b9c Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

llvm-svn: 76437
 2009-07-20 17:43:30 +00:00
Dan Gohman 7d82e1338e Make GetElementPtr ConstantExprs default to having no pointer overflow.

Owen Anderson 20b34ac794 Move the ConstantInt uniquing table into LLVMContextImpl. This exposed a number of issues in 
our current context-passing stuff, which is also fixed here

Owen Anderson f945a9ed07 Move a few more convenience factory functions from Constant to LLVMContext.

Duncan Sands c5928d2fad The static function TypeToFloatSemantics is now 
unused - remove it.

Owen Anderson b6b2530000 Move EVER MORE stuff over to LLVMContext.

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").

Owen Anderson 3e42e9f2fc Move more functionality over to LLVMContext. 
llvm-svn: 75559
 2009-07-13 23:50:59 +00:00
Owen Anderson 13c240a4c1 Move a bit more functionality to LLVMContext, which apparently wasn't being used anyways. 
llvm-svn: 75546
 2009-07-13 23:16:26 +00:00
Owen Anderson e4dcecd006 As Chris pointed out, this doesn't actually need an LLVMContext to operate. 
llvm-svn: 75508

Owen Anderson 542619e6d5 Move more functionality over to LLVMContext.

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

Torok Edwin 69208f0f9e Remove extra \n from LLVM_UNREACHABLE calls. 
llvm-svn: 75416
 2009-07-12 07:15:17 +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.

llvm-svn: 75379
 2009-07-11 20:10:48 +00:00
Torok Edwin ccb29cd290 Convert more assert(0)+abort() -> LLVM_UNREACHABLE, 
and abort()/exit() -> llvm_report_error().

llvm-svn: 75363
 2009-07-11 13:10:19 +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.

Owen Anderson 5c96ef7c4e Have scoped mutexes take referenes instead of pointers.

Owen Anderson 0d2de8c35e Revert r73790, and replace it with a significantly less ugly solution. Rather than trying to make the global reader-writer lock work, 
create separate recursive mutexes for each value map.  The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.

llvm-svn: 73801
 2009-06-20 00:24:58 +00:00
Owen Anderson b07dd959a4 Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation 
gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.

llvm-svn: 73790
 2009-06-19 23:16:19 +00:00
Owen Anderson 59ba814f39 Forgot to remove some explicit locking when it became implicit in the ValueMap. 
llvm-svn: 73778
 2009-06-19 18:34:09 +00:00
Owen Anderson d830eb8365 Simplify a lot of code by using a R/W mutex that becomes a no-op when multithreading is disabled. 
llvm-svn: 73714
