git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233647 91177308-0d34-0410-b5e6-96231b3b80d8
The only user of `DebugLoc::getFromDILexicalBlock()` was creating a new
`MDLocation` as convenient API for passing an `MDScope`. Stop doing
that, and remove the API. If in the future we actually *want* to create
new DebugLocs, calling `MDLexicalBlock::get()` makes more sense.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233643 91177308-0d34-0410-b5e6-96231b3b80d8
Pervasively use the types provided by the debug info hierarchy rather
than `MDNode` in `LexicalScopes`.
I noticed (again, I guess, based on comments in the implementation?)
that `DILexicalBlockFile::getScope()` returns something different from
`DILexicalBlockFile::getContext()`. I created a local helper for
getting the same logic from `MDLexicalBlockFile` called
`getScopeOfScope()`. I still don't really understand it, but I've added
some FIXMEs and I'll come back to it (I suspect the way we encode these
objects isn't really ideal).
Note that my previous commit r233610 accidentally changed behaviour in
`findLexicalScope()` -- it transitioned from a call to
`DILexicalBlockFile::getScope()` to `MDLexicalBlockFile::getScope()`
(sounds right, doesn't it?) -- so I've fixed that as a drive-by. No
tests failed with my error, so it looks like we're missing some coverage
here... when I come back to understand the logic, I'll see if I can add
some.
Other than the fix to `findLexicalScope()`, no functionality change.

When we expand the RET_ReallyLR pseudo instruction we also need to transfer the
implicit operands.
The return register is an implicit operand and without it the liveness
calculation generates an incorrect live-out set for the patchpoint.
This fixes rdar://problem/19068476.

There's no benefit to using `DebugLoc` here. Moreover, this will let a
follow-up commit work with `MDScope` directly instead of `DebugLoc`.

This pushes the use of PointerType::getElementType up into several
callers - I'll essentially just have to keep pushing that up the stack
until I can eliminate every call to it...

Keep a note in the materializer that we are stripping debug info so that
user doing a lazy read of the module don't hit outdated formats.

Since I'm slowly gutting `DISubprogram` and `DICompileUnit`, update the

moving to).

Don't use `DebugLoc::getFnDebugLoc()`, which creates new `MDLocation`s,

Remove old API for `DebugLoc` now that all the callers have been
updated. If this broke your out-of-tree build, here's a quick map from
the old API to the new one:
DebugLoc DebugLoc::getFromMDLocation(MDNode *)
=> DebugLoc::DebugLoc(MDLocation *)
=> explicit DebugLoc::DebugLoc(MDNode *) // works with broken code
MDNode *DebugLoc::getAsMDNode(LLVMContext &)
=> MDLocation *DebugLoc::get()
=> DebugLoc::operator MDLocation *()
=> MDNode *DebugLoc::getAsMDNode() // works with broken code
bool DebugLoc::isUnknown()
=> DebugLoc::operator MDLocation *()
i.e.: if (MDLocation *DL = ...)
=> DebugLoc::operator bool() // works with broken code
i.e.: if (DebugLoc DL = ...)
void DebugLoc::getScopeAndInlinedAt(MDNode *&, MDNode *&)
=> use: MDNode *DebugLoc::getScope()
and: MDLocation *DebugLoc::getInlinedAt()
MDNode *DebugLoc::getScopeNode(LLVMContext &)
=> MDNode *DebugLoc::getInlinedAtScope()
void DebugLoc::dump(LLVMContext &)
=> void DebugLoc::dump()
void DebugLoc::getFnDebugLoc(LLVMContext &)
=> void DebugLoc::getFnDebugLoc()
MDNode *DebugLoc::getScope(LLVMContext &)
=> MDNode *DebugLoc::getScope()
MDNode *DebugLoc::getInlinedAt(LLVMContext &)
=> MDLocation *DebugLoc::getInlinedAt()
I've noted above the only functions that won't crash on broken code (due
to downcasting to `MDLocation`). If your code could be dealing with
broken IR (i.e., you haven't run the verifier yet, or you've used a
temporary node that will eventually (but not yet) get RAUW'ed to an
`MDLocation`), you need to restrict yourself to those.

Update lib/IR and lib/Bitcode to use the new `DebugLoc` API. Added an
explicit conversion to `bool` (avoiding a conversion to `MDLocation`),
since a couple of these use cases need to handle broken code.

Adds a test to verify the behavior that r233153 restored: 'optnone'
does not spuriously disable the DAG combiner, and in fact there are
cases where the DAG combiner must run (even at -O0 or 'optnone') in
order for codegen to succeed.

When a new SM architecture is introduced, it is only supported by the
current PTX version and later. Make sure we are using at least the
minimum PTX version for the target architecture.
This also removes support for PTX ISA < 3.2.

There was a change to the way some of the HTM and crypto builtins are being
handled in Clang. Previously, some of the builtins were dealt with in the
CodeGenFunction::EmitPPCBuiltinExpr method (in order to do range checking on
constant arguments). These check will been moved to Sema
http://reviews.llvm.org/D8672), which means those builtins will not be handled
in the EmitPPCBuiltinExpr method anymore. As a result, the definition of the
intrinsics in IntrinsicsPowerPC.td needs to be modified to inherit from the
GCCBuiltin definition.

Rewrite `DebugLoc` with a cleaner API that reflects its current status
as a wrapper around an `MDLocation` pointer.
- Add accessors/constructors to/from `MDLocation`.
- Simplify construction from `MDNode`.
- Remove unnecessary `LLVMContext` from APIs.
- Drop some API that isn't useful any more.
- Rewrite documentation.
Actually, I've left the old API behind temporarily at the bottom of the
class so that I can update callers in separate commits. I'll remove it
once the callers are updated.

This follows the inlined-at linked list and returns the scope of the
