CWriter class. Write directly to stream instead of building a big
string, then writing it out.
- Implement printing of ConstantPointerRefs
llvm-svn: 3389
when they are destroyed, which makes Constant::destroyConstant an actually
useful external interface. Expose these methods publicly.
- Implement destroyConstant on ConstPointerNull so that destroyConstant can
be used on any derived type constant safely.

- ParseConstantPool was resolving reference to value using the function
slot # instead of the global slot #.
- Bytecode reader changes:
- Remove the failure<> template from Bytecode Reader
- Remove extraneous #includes
- s/method/function/ a bit
- Eliminate the fwdRefs class that just added abstraction where it was not
needed, making things more complex.
- Use a vector instead of a list for function signatures.
llvm-svn: 3366
- Changed parser to always use parenthesis on ConstExprs to be consistent
- Parser now passes TRUE and FALSE tokens as a special case of the ConstExpr
machinery instead of a special case of constant int stuff
- Fix the AsmParser to use ValueRef ::= ConstExpr, and remove
ResolvedVal ::= ConstExpr this allows constexprs to be used in PHI nodes

but is instead implemented with XOR. Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees. But these tree nodes are now binary, not unary.

This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads. Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.

- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
- get register name methods now return const char * const pointers instead
of std::string's.
- Added file header comments to SparcRegClassInfo.(cpp|h)
- Moved BIG constant arrays out of SparcRegClassInfo.h, into
SparcRegInfo.cpp. This should allow a LOT of std::string constructors to
not have to be called.
llvm-svn: 3295
* New ReplaceInstUsesWith function to factor out tons of common code
This needs to be used more in the future still, but it's a good start
* New InsertNewInstBefore to allow multi-instruction replacements
* Change getMaxValue functions to isAllOnesValue function, which doesn't
have to CREATE/lookup a new constant. Also the name is accurate
* Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne
functions: This should be moved to Constant* classes eventually
* Implement xor X, ALLONES -> not X
* Fold ALL setcc's of booleans away
* Handle various SetCC's for integers against values at the end of their
ranges, possibly off by one. This implements the setcc-strength-reduce.ll
testcase.
llvm-svn: 3286
Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.
llvm-svn: 3244
- Reenable gep (gep x) -> x
- Make instcombine do dead instruction elimination where it's really
easy. Now visitors don't have to ensure they aren't not processing
dead instructions.

Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.

* Internalize global variables with initializers
* Add new stat to track global variable internalization
* Only count functions that were not internal before in internalized function
count

* Correctly delete TypeHandles in AsmParser. In addition to not leaking
memory, this prevents a bug that could have occurred when a type got
resolved that the constexpr was using
* Check for errors in the AsmParser instead of hitting assertion failures
deep in the code
* Simplify the interface to the ConstantExpr class, removing unneccesary
parameters to the ::get* methods.
* Rename the 'getelementptr' version of ConstantExpr::get to
ConstantExpr::getGetElementPtr

* Implement stuff so that code can declare that they only depend on the CFG of
a function, not on anything else. This speeds up GCCAS a lot.

is platform independant afterall.
* Object orientize the functions, cleanup code a bit. Instead of static
global functions, the helpers for instruction selection are now part of
the InstructionSelection Pass class.

old call instruction
* Implement conversion of return values for calls. This fixes bug:
test/Regression/Transforms/FunctionResolve/retmismatch3.ll
llvm-svn: 3140
which was caused by us not running the "drop references of dead
instructions" code when there were no basic blocks that were dead.
We still don't want to do some of the stuff we do if there are dead
basic blocks, but we DO want to drop references of dead instructions,
so we factor the common code out to a new method.

* Eliminate AnalysisID: Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
the analyses themselves.
