Implement support to debug inlined functions.

Fix a pretty serious misfeature of the inliner: if it inlines a function
with multiple return values it inserts a PHI to merge them all together.
However, if the return values are all the same, it ends up with a pointless
PHI and this pointless PHI happens to really block SRoA from happening in
at least a silly C++ example written by Doug, but probably others. This
fixes rdar://7339069.

Simplify some code (first hunk) and fix PR5208 (second hunk) by
updating the callgraph when introducing a call.

llvm-svn: 84310

Introduce and use convenience methods for getting pointer types
where the element is of a basic builtin type. For example, to get
an i8* use getInt8PtrTy.

llvm-svn: 83379

Instruction::clone does not need to take an LLVMContext&. Remove that and
update all the callers.

llvm-svn: 82889

Fix comment.

llvm-svn: 81138

remove a bunch of explicit code previously needed to update the
callgraph. This is now dead because RAUW does the job.

for sanity. This didn't turn up any bugs.

Change CallGraphNode to maintain it's Function as an AssertingVH
for sanity. This didn't turn up any bugs.

Change CallGraphNode to maintain its "callsite" information in the
call edges list as a WeakVH instead of as an instruction*. This fixes
a broad class of dangling pointer bugs, and makes CallGraph have a number
of useful invariants again. This fixes the class of problem indicated
by PR4029 and PR3601.

Reapply 79977.
Use MDNodes to encode debug info in llvm IR.

llvm-svn: 80406

enhance InlineFunction to be able to optionally return
a the list of static allocas that it inlined.

llvm-svn: 80203

smallvectorize the list of returns built by CloneAndPruneFunctionInto.

llvm-svn: 80202

reduce inlining factor some stuff out to a static helper function,
and other code cleanups. No functionality change.

llvm-svn: 80199

Revert 79977. It causes llvm-gcc bootstrap failures on some platforms.

llvm-svn: 80073

Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata

Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

Push LLVMContexts through the IntegerType APIs.

llvm-svn: 78948

Move more code back to 2.5 APIs.

llvm-svn: 77635

Move types back to the 2.5 API.

llvm-svn: 77516

Move ConstantExpr to 2.5 API.

llvm-svn: 77494

Revert the ConstantInt constructors back to their 2.5 forms where possible, thanks to contexts-on-types. More to come.

llvm-svn: 77011

Get rid of the Pass+Context magic.

llvm-svn: 76702

Revert yesterday's change by removing the LLVMContext parameter to AllocaInst and MallocInst.

llvm-svn: 75863

Move EVER MORE stuff over to LLVMContext.

llvm-svn: 75703

This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

llvm-svn: 75200

More LLVMContext-ification.
