Chuck Rose III 1a39a2d13d VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control. 
This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these 
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in 
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.

Devang Patel 6ba5ad482f - Undo previous check and allow loop switch for condtion that is not inside

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Reid Spencer 557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

Chris Lattner 1bfc7ab6a7 Switch inliner over to use DenseMap instead of std::map for ValueMap. This

Reid Spencer a94d394ad2 For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

 2007-01-13 00:02:49 +00:00
Reid Spencer cddc9dfe97 Implement review feedback for the ConstantBool->ConstantInt merge. Chris 
recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

Reid Spencer 266e42b312 For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

Chris Lattner 79a42ac941 Switch over Transforms/Scalar to use the STATISTIC macro. For each statistic 
converted, we lose a static initializer.  This also allows GCC to emit warnings
about unused statistics.

 2006-12-19 21:40:18 +00:00
Chris Lattner 700b873130 Detemplatize the Statistic class. The only type it is instantiated with

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.
