* Minor code simplification suggested by DuncanMatt Arsenault2013-07-271-2/+1
| | | | llvm-svn: 187309
* Debug Info Verifier: verify SPs in llvm.dbg.sp.Manman Ren2013-07-271-3/+9
| | | | | | | | Also always add DIType, DISubprogram and DIGlobalVariable to the list in DebugInfoFinder without checking them, so we can verify them later on. llvm-svn: 187285
* Use more parens to clarify assert.Eric Christopher2013-07-261-1/+1
| | | | llvm-svn: 187247
* Debug Info Verifier: enable verification of DICompileUnit.Manman Ren2013-07-261-3/+0
| | | | | | | | We used to call Verify before adding DICompileUnit to the list, and now we remove the check and always add DICompileUnit to the list in DebugInfoFinder, so we can verify them later on. llvm-svn: 187237
* Collapse conditional and add an assert for unhandled scope types.Eric Christopher2013-07-261-3/+1
| | | | llvm-svn: 187224
* Re-add DataLayout pointer size convenience functions.Matt Arsenault2013-07-261-0/+10
| | | | | | | | These were reverted in r167222 along with the rest of the last different address space pointer size attempt. These will be used in later commits. llvm-svn: 187223
* Add a way to get the context of any particular scope.Eric Christopher2013-07-261-0/+25
| | | | llvm-svn: 187212
* Debug Info: update comments and add a FIXME.Manman Ren2013-07-251-2/+5
| | | | llvm-svn: 187157
* Debug Info: improve the verifier to check field types.Manman Ren2013-07-251-0/+4
| | | | | | | Make sure the context field of DIType is MDNode. Fix testing cases to make them pass the verifier. llvm-svn: 187150
* Add a way to add a kind-value string pair to an attribute.Bill Wendling2013-07-251-0/+7
| | | | llvm-svn: 187138
* Debug Info: improve the verifier to check field types.Manman Ren2013-07-251-0/+45
| | | | | | | | Make sure the context and type fields are MDNodes. We will generate verification errors if those fields are non-empty strings. Fix testing cases to make them pass the verifier. llvm-svn: 187106
* Make these methods const correct.Rafael Espindola2013-07-251-2/+1
| | | | | | Thanks to Nick Lewycky for noticing it. llvm-svn: 187098
* Replace the "NoFramePointerElimNonLeaf" target option with a function attribute.Bill Wendling2013-07-251-0/+4
| | | | | | | | There's no need to specify a flag to omit frame pointer elimination on non-leaf nodes...(Honestly, I can't parse that option out.) Use the function attribute stuff instead. llvm-svn: 187093
* Debug Info: improve the Finder.Manman Ren2013-07-241-0/+1
| | | | | | | Improve the Finder to handle context of a DIVariable used by DbgValueInst. Fix testing cases to make them pass the verifier. llvm-svn: 187052
* Replace with a "null" RAUW with an assert since we'd actually likeEric Christopher2013-07-241-8/+8
| | | | | | to assume we're replacing. Clarify comments. llvm-svn: 187018
* Remove dead code.Eric Christopher2013-07-241-5/+0
| | | | llvm-svn: 187017
* Remove unnecessary constructors as the default conversions will handleEric Christopher2013-07-241-18/+0
| | | | | | | all enumerated cases. Reformat the rest of the existing constructors to match. llvm-svn: 187015
* More constructor cleanup.Eric Christopher2013-07-241-6/+0
| | | | | | | Move to a single constructor with a default argument and avoid the check and nullification. llvm-svn: 187014
* Collapse logic and move and reword comment for clarity.Eric Christopher2013-07-241-3/+5
| | | | llvm-svn: 187013
* Add a fixme and reformat.Eric Christopher2013-07-241-4/+3
| | | | llvm-svn: 187012
* Debug Info: improve the Finder.Manman Ren2013-07-231-0/+9
| | | | | | | Improve the Finder to handle context of a DIVariable. If Scope is a DICompileUnit, add it to the list of CUs. llvm-svn: 187003
* Debug Info: clean up.Manman Ren2013-07-231-18/+6
| | | | llvm-svn: 187002
* Remove unused function.Eric Christopher2013-07-231-7/+0
| | | | llvm-svn: 187001
* Debug Info: code cleanup, use getNodeField if possible.Manman Ren2013-07-231-28/+15
| | | | | | | Use getNodeField to access a field as a MDNode. No functionality change. llvm-svn: 186985
* DebugInfo Verifier: verify the actual type.Manman Ren2013-07-231-0/+10
| | | | llvm-svn: 186972
* Debug Info Finder: use processDeclare and processValue to list debug infoManman Ren2013-07-232-1/+36
| | | | | | | | | | | MDNodes used by DbgDeclareInst and DbgValueInst. Another 16 testing cases failed and they are disabled with -disable-debug-info-verifier. A total of 34 cases are disabled with -disable-debug-info-verifier and will be corrected. llvm-svn: 186902
* Debug Info Finder: add processScope to actually handle the Scope.Manman Ren2013-07-221-3/+23
| | | | | | Instead of just adding the scope to the list, we actually handle the scope. llvm-svn: 186867
* Disallow global aliases to bitcast between address spacesMatt Arsenault2013-07-201-4/+15
| | | | llvm-svn: 186767
* Remove trailing whitespace, fix file path in commentMatt Arsenault2013-07-202-38/+38
| | | | llvm-svn: 186766
* Debug Info Verifier: simplify DIxxx::VerifyManman Ren2013-07-202-28/+17
| | | | | | | | Simplify DIxxx:Verify to not call Verify on an operand. Instead, we use DebugInfoFinder to list all MDNodes that should be a DIScope and all MDNodes that should be a DIType and we will call Verify on those lists. llvm-svn: 186737
* s/compiler_used/compiler.used/.Rafael Espindola2013-07-191-1/+1
| | | | | | | We were incorrectly using compiler_used instead of compiler.used. Unfortunately the passes using the broken name had tests also using the broken name. llvm-svn: 186705
* Remove DIBuilder cache of variable TheCU and change the fewEric Christopher2013-07-191-14/+18
| | | | | | | uses that wanted it. Also change the interface for createCompileUnit to compensate. Fix comments that refer to TheCU as well. llvm-svn: 186637
* Debug Info: enable verifying by default and disable testing cases that fail.Manman Ren2013-07-192-0/+34
| | | | | | | | | | | | | | | | | | | 1> Use DebugInfoFinder to find debug info MDNodes. 2> Add disable-debug-info-verifier to disable verifying debug info. 3> Disable verifying for testing cases that fail (will update the testing cases later on). 4> MDNodes generated by clang can have empty filename for TAG_inheritance and TAG_friend, so DIType::Verify is modified accordingly. Note that DebugInfoFinder does not list all debug info MDNode. For example, clang can generate: metadata !{i32 786468}, which will fail to verify. This MDNode is used by debug info but not included in DebugInfoFinder. This MDNode is generated as a temporary node in DIBuilder::createFunction Value *TElts[] = { GetTagConstant(VMContext, DW_TAG_base_type) }; MDNode::getTemporary(VMContext, TElts) llvm-svn: 186634

* Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.Charles Davis2013-07-121-0/+2
| | | | | | | | | | | | | | | Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

* Reduce the number of indirections in the attributes implementation.Benjamin Kramer2013-07-112-178/+131
| | | | | | | | | | | - Coallocate entires for AttributeSetImpls and Nodes after the class itself. - Remove mutable iterators from immutable classes. - Remove unused context field from AttributeImpl. - Derive Enum/Align/String attribute implementations from AttributeImpl instead of having a whole new inheritance tree for them. - Derive AlignAttributeImpl from EnumAttributeImpl. llvm-svn: 186075
* Don't assert if we can't constant fold extract/insertvalueHal Finkel2013-07-101-8/+21
| | | | | | | | | | | | | | | A non-constant-foldable static initializer expression containing insertvalue or extractvalue had been causing an assert: Constants.cpp:1971: Assertion `FC && "ExtractValue constant expr couldn't be folded!"' failed. Now we report a more-sensible "Unsupported expression in static initializer" error instead. Fixes PR15417. llvm-svn: 186044
* Revert "DebugInfo: remove unused helper function getDICompositeType."Eric Christopher2013-07-091-0/+11
| | | | | | | This reverts commit r185876 as the functions appear to still be used by dragonegg. llvm-svn: 185890

* DebugInfo: Consider global variables without locations to be validDavid Blaikie2013-07-041-3/+0
| | | | | | | | | | | | | | | | | We were being a bit too aggresive here in classifying global variables with no global reference or constant value to be invalid - this would cause LLVM to not emit the DWARF description of the global variable if it had been optimized away, which isn't helpful for users who might benefit from the global variable's description even if there's no location information. This also fixes a crasher issue here that I was unable to reduce a test case for - involving a using decl (& subsequent DW_TAG_imported_declaration ) of such a global variable that, once optimized away, would crash when an attempt to emit the imported declaration was made. llvm-svn: 185675

* IRVerifier: Correctly check attribute typesTobias Grosser2013-07-021-1/+2
| | | | | | | | | | | Add missing parenthesis such that all and not only the very first attribute is checked. Testing this piece of code is not possible with an LLVM-IR test file, as the LLVM-IR parser has a similar check such that the wrong IR does not even arrive at the verifier. llvm-svn: 185408
* Debug Info: clean up usage of Verify.Manman Ren2013-07-011-16/+18
| | | | | | | No functionality change. It should suffice to check the type of a debug info metadata, instead of calling Verify. llvm-svn: 185383
