* Remove the vast majority of the Destroy methods from the AST library,Douglas Gregor2010-07-251-1/+0
| | | | | | since we aren't going to be calling them ever. llvm-svn: 109377
* Sema: Fix a bug with #pragma options align=reset, reset against an empty stackDaniel Dunbar2010-07-161-14/+23
| | | | | | is well defined, it resets to the default alignment. llvm-svn: 108508
* Sema: Fix comment, apparently #pragma options align=power is just the same asDaniel Dunbar2010-05-281-6/+1
| | | | | | align=native, at least for the platforms we support. llvm-svn: 105000
* Sema: Just ignore '#pragma options align=power' for now, this is no worse thanDaniel Dunbar2010-05-281-1/+6
| | | | | | | what we used to be doing, and makes sure that paired '#pragma options align=reset' won't fail. llvm-svn: 104998
* Parse/Sema: Add support for '#pragma options align=packed', which, it should beDaniel Dunbar2010-05-271-0/+7
| | | | | | noted, is not the same as __attribute__((packed)). That would be ridiculous! llvm-svn: 104865
* Parse/Sema: Add support for '#pragma options align=native'.Daniel Dunbar2010-05-271-0/+4
| | | | llvm-svn: 104864
* Sema: Add initial support for '#pragma options align=mac68k'.Daniel Dunbar2010-05-271-7/+16
| | | | | | | - Docs are fairly sketchy, if someone wants to pore through gcc to look for holes I'd appreciate any failing test cases! llvm-svn: 104809
* Sema: Factor out struct for alignment stack entries.Daniel Dunbar2010-05-271-5/+11
| | | | llvm-svn: 104799
* Sema: Replace getPragmaPackAlignment with AddAlignmentAttributesForRecord, whichDaniel Dunbar2010-05-271-6/+10
| | | | | | exposes less details. llvm-svn: 104797
* Sema: Reject '#pragma options align=mac68k' everywhere except i386-apple-darwin.Daniel Dunbar2010-05-271-0/+14
| | | | llvm-svn: 104789
* Sema: Support for #pragma options align={reset,natural}. '#pragma options align'Daniel Dunbar2010-05-271-1/+36
| | | | | | shares the stack with '#pragma pack', who knew!? llvm-svn: 104786
* Protect isIntegerConstantExpr from seeing type- or value-dependentDouglas Gregor2010-05-181-1/+3
| | | | | | expressions in attributes, pragmas. llvm-svn: 104083
* Rip out the last remaining implicit use of OverloadedFunctionDecl in Sema:John McCall2009-12-021-5/+4
| | | | | | | LookupResult::getAsSingleDecl() is no more. Shift Sema::LookupSingleName to return null on overloaded results. llvm-svn: 90309
* Split LookupResult into its own header.John McCall2009-11-181-0/+1
| | | | llvm-svn: 89199
* Carry lookup configuration throughout lookup on the LookupResult. GiveJohn McCall2009-11-171-4/+2
| | | | | | | | | | | | | LookupResult RAII powers to diagnose ambiguity in the results. Other diagnostics (e.g. access control and deprecation) will be moved to automatically trigger during lookup as part of this same mechanism. This abstraction makes it much easier to encapsulate aliasing declarations (e.g. using declarations) inside the lookup system: eventually, lookup will just produce the aliases in the LookupResult, and the standard access methods will naturally strip the aliases off. llvm-svn: 89027
* Refactor the LookupResult API to simplify most common operations. Require ↵John McCall2009-10-091-5/+4
| | | | | | | | | users to pass a LookupResult reference to lookup routines. Call out uses which assume a single result. llvm-svn: 83674
* Remove tabs, and whitespace cleanups.Mike Stump2009-09-091-19/+19
| | | | llvm-svn: 81346
* Per advice that Doug Gregor gave me several months ago, clean up theTed Kremenek2009-08-031-31/+24
| | | | | | | | | | | | | implementation of '#pragma unused' by not constructing intermediate DeclRefExprs, but instead do the name lookup directly. The implementation is greatly simplified. Along the way, degrade '#pragma unused(undeclaredvariable)' to a warning instead of being a hard error. This implements: <rdar://problem/6761874> [sema] allow #pragma unused to reference undefined variable (with warning) llvm-svn: 78019
* Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis2009-06-301-1/+1
| | | | | | | | | The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. llvm-svn: 74501
* Move the static DeclAttrs map into ASTContext. Fixes <rdar://problem/6983177>.Douglas Gregor2009-06-181-1/+1
| | | | llvm-svn: 73702
* Deallocate 'DeclRefExpr's in correctly formed '#pragma unused'Ted Kremenek2009-03-231-0/+1
| | | | llvm-svn: 67573
* Implement '#pragma unused'.Ted Kremenek2009-03-231-0/+38
| | | | llvm-svn: 67569
* Handle #pragma pack(0). I left this out of diagnostic because users shouldDaniel Dunbar2009-03-061-2/+4
| | | | | | | really use pack() instead. - <rdar://problem/6650243> clang warns about '#pragma pack(0)' llvm-svn: 66287
* Make PragmaPackStack be a private class in SemaAttr and make itsChris Lattner2009-02-171-31/+91
| | | | | | instance in Sema be a pimpl. llvm-svn: 64718
* move attribute(packed) sema support out of SemaDecl into a new SemaAttr.cpp ↵Chris Lattner2009-02-171-0/+110
