* DebugLoc: Remove getFromDILexicalBlock()Duncan P. N. Exon Smith2015-03-304-27/+14
| | | | | | | | | 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. llvm-svn: 233643
* LexicalScopes: Use debug info hierarchy pervasivelyDuncan P. N. Exon Smith2015-03-303-53/+66
| | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 233640

* Transfer implicit operands when expanding the RET_ReallyLR pseudo instruction.Juergen Ributzka2015-03-302-3/+53
| | | | | | | | | | | | 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. llvm-svn: 233635

* DebugInfo: Remove dead code from old DebugLoc APIDuncan P. N. Exon Smith2015-03-302-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 233599

* [PPC] Modify HTM and crypto intrinsics to inherit from GCCBuiltinKit Barton2015-03-301-8/+9
| | | | | | | | | | | | | | | 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. http://reviews.llvm.org/D8673 llvm-svn: 233581

| | | | | | | | | | | | | | | | | 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. llvm-svn: 233573
