land David Blaikie's patch to de-constify Type, with a few tweaks.

llvm-svn: 135375

Convert CallInst and InvokeInst APIs to use ArrayRef.

llvm-svn: 135265

Inline check that's used only once.

llvm-svn: 128465

Rework the logic (and removing the bad check for an unreachable block) so that
the FailBB dominator is correctly calculated. Believe it or not, there isn't a
functionality change here.

Don't try to add stack protector logic to a dead basic block. It messes up
dominator information.

llvm-svn: 128452

In some cases, the "fail BB dominator" may be null after the BB was split (and
becomes reachable when before it wasn't). Check to make sure that it's not null
before trying to use it.

Make more passes preserve dominators (or state that they preserve dominators if
they all ready do). This removes two dominator recomputations prior to isel,
which is a 1% improvement in total llc time for 403.gcc.

The only potentially suspect thing is making GCStrategy recompute dominators if
it used a custom lowering strategy.

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
must be called in the pass's constructor. This function uses static dependency

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems
with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

Now with fewer extraneous semicolons!

llvm-svn: 115996

Reapply r110396, with fixes to appease the Linux buildbot gods.

llvm-svn: 110460

Revert r110396 to fix buildbots.

llvm-svn: 110410

Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static
ID member as the sole unique type identifier. Clean up APIs related to this change.

llvm-svn: 110396

Fix batch of converting RegisterPass<> to INTIALIZE_PASS().

llvm-svn: 109045

tighten up this code.

llvm-svn: 107670

Fix up -fstack-protector on linux to use the segment
registers. Split out testcases per architecture and os
now.

Patch from Nelson Elhage.

llvm-svn: 107640

Uniformize the names of type predicates: rather than having isFloatTy and
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris!

llvm-svn: 96223

Move remaining stuff to the isInteger predicate.

llvm-svn: 92771

Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit

Neuter stack protectors by only checking character arrays. This is what GCC
does.

llvm-svn: 84916

Push LLVMContexts through the IntegerType APIs.

llvm-svn: 78948

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

Rename PaddedSize to AllocSize, in the hope that this
will make it more obvious what it represents, and stop
it being confused with the StoreSize.
