| | | | | | | | Generate tables in the .xdata section representing what actions to take when an exception is thrown. This currently fills in state for cleanups, catch handlers are still unfinished. llvm-svn: 233636
* Transfer implicit operands when expanding the RET_ReallyLR pseudo instruction.Juergen Ributzka2015-03-301-3/+6
| | | | | | | | | | | | 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

| | | | | | | | | Keep a note in the materializer that we are stripping debug info so that user doing a lazy read of the module don't hit outdated formats. Thanks to Duncan for suggesting the fix. llvm-svn: 233603
* DwarfDebug: Avoid creating new DebugLocs in the backendDuncan P. N. Exon Smith2015-03-302-5/+9
| | | | | | | Don't use `DebugLoc::getFnDebugLoc()`, which creates new `MDLocation`s, in the backend. We just want to grab the subprogram here anyway. llvm-svn: 233601
* DebugInfo: Remove dead code from old DebugLoc APIDuncan P. N. Exon Smith2015-03-301-9/+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

* MC: For variable symbols, maintain MCSymbol::Section as a cache.Peter Collingbourne2015-03-304-29/+4
| | | | | | | | | | | This fixes the visibility of symbols in certain edge cases involving aliases with multiple levels of indirection. Fixes PR19582. Differential Revision: http://reviews.llvm.org/D8586 llvm-svn: 233595
* Transforms: Use the new DebugLoc API, NFCDuncan P. N. Exon Smith2015-03-307-28/+30

* IR: Use the new DebugLoc API, NFCDuncan P. N. Exon Smith2015-03-306-39/+28
| | | | | | | | 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. llvm-svn: 233585
* [NVPTX] Associate a minimum PTX version for each SM architectureJustin Holewinski2015-03-301-9/+5
| | | | | | | | | | 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. llvm-svn: 233583
* CodeGen: Use the new DebugLoc API, NFCDuncan P. N. Exon Smith2015-03-309-60/+39

* DebugInfo: Write new DebugLoc APIDuncan P. N. Exon Smith2015-03-301-53/+63
| | | | | | | | | | | | | | | | | 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
* DebugInfo: Implement MDLocation::getInlinedAtScope()Duncan P. N. Exon Smith2015-03-302-6/+2
| | | | | | | | | Write `MDLocation::getInlinedAtScope()` and use it to re-implement `DebugLoc::getScopeNode()` (and simplify `DISubprogram::Verify()`). This follows the inlined-at linked list and returns the scope of the deepest/last location. llvm-svn: 233568

* Verifier: Loosen r233559 check for 'function:' field in MDSubprogramDuncan P. N. Exon Smith2015-03-301-3/+2
| | | | | | | | | | Stop worrying about what the `function:` field is in `MDSubprogram`, since it could be a bitcast [1]. Just check its type and leave it at that. [1]: http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_build/3540/ llvm-svn: 233562
* Verifier: Add operand checks for MDLexicalBlockDuncan P. N. Exon Smith2015-03-305-12/+24
| | | | | | | | | | Add operand checks for `MDLexicalBlock` and `MDLexicalBlockFile`. Like `MDLocalVariable` and `MDLocation`, these nodes always require a scope. There was no test bitrot to fix here (just updated the serialization tests in test/Assembler/mdlexicalblock.ll). llvm-svn: 233561
* Verifier: Check operands of MDSubprogram nodesDuncan P. N. Exon Smith2015-03-304-31/+94
| | | | | | | | | | | Check operands of `MDSubprogram`s in the verifier, and update the accessors and factory functions to use more specific types. There were a lot of broken testcases, which I fixed in r233466. If you have out-of-tree tests for debug info, you probably need similar changes to the ones I made there. llvm-svn: 233559

* [SystemZ] Fix LLVM crash on unoptimized codeUlrich Weigand2015-03-301-0/+2
| | | | | | | | | | | | | | Compiling the following function with -O0 would crash, since LLVM would hit an assertion in getTestUnderMaskCond: int test(unsigned long x) { return x >= 0 && x <= 15; } Fixed by detecting the case in the caller of getTestUnderMaskCond. llvm-svn: 233541

* Special case the creation of relocation sections.Rafael Espindola2015-03-302-6/+15
| | | | | | | | | | | These sections are never looked up and we know when have to create them. Use that to save adding them to the regular map and avoid a symbol->string->symbol conversion for the group symbol. This also makes the implementation independent of the details of how unique sections are implemented. llvm-svn: 233539
* [mips] Support 9-bit offsets for the 'R' inline assembly memory constraint.Daniel Sanders2015-03-301-1/+14
| | | | | | | | | | | | | | | | | | | Summary: The 'R' constraint is actually supposed to be much more complicated than this and is defined in terms of whether it will cause macro expansion in the assembler. 'R' is getting less useful due to architecture changes and ought to be replaced by other constraints. We therefore implement 9-bit offsets which will work for all subtargets and all instructions.
