2011-08-04Add partial support for using anonymous bitfields (e.g., int : 0) to enforce Chad Rosier
alignment. This fixes cases where the anonymous bitfield is followed by a non-bitfield member. E.g., struct t4 { int foo : 1; long : 0; char bar; }; Part of rdar://9859156 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136858 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-19Revamp the SourceManager to separate the representation of parsedDouglas Gregor
source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135484 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx ↵Eli Friedman
should not imply -mno-sse. Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__. clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much. <rdar://problem/9694837> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134770 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Fix a FIXME in clang ARM driver that was exposed as a bug with ARM backendEvan Cheng
change. Previously clang was passing the following feature strings to the ARM backend when CPU is cortex-a8: +neon,-vfp2,-vfp3 This used to work because -vfp2,-vfp3 had no effect after +neon. Now that the features are controlled by individual bits (with implied hierarchy), the net effect is all three features will be turned off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134691 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-07Keep track of which source locations are part of a macro argumentChandler Carruth
instantiation and improve diagnostics which are stem from macro arguments to trace the argument itself back through the layers of macro expansion. This requires some tricky handling of the source locations, as the argument appears to be expanded in the opposite direction from the surrounding macro. This patch provides helper routines that encapsulate the logic and explain the reasoning behind how we step through macros during diagnostic printing. This fixes the rest of the test cases originially in PR9279, and later split out into PR10214 and PR10215. There is still some more work we can do here to improve the macro backtrace, but those will follow as separate patches. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134660 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-07Make the Preprocessor more memory efficient and improve macro instantiation ↵Argyrios Kyrtzidis
diagnostics. When a macro instantiation occurs, reserve a SLocEntry chunk with length the full length of the macro definition source. Set the spelling location of this chunk to point to the start of the macro definition and any tokens that are lexed directly from the macro definition will get a location from this chunk with the appropriate offset. For any tokens that come from argument expansion, '##' paste operator, etc. have their instantiation location point at the appropriate place in the instantiated macro definition (the argument identifier and the '##' token respectively). This improves macro instantiation diagnostics: Before: t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int') int y = M(/); ^~~~ t.c:5:11: note: instantiated from: int y = M(/); ^ After: t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int') int y = M(/); ^~~~ t.c:3:20: note: instantiated from: \#define M(op) (foo op 3); ~~~ ^ ~ t.c:5:11: note: instantiated from: int y = M(/); ^ The memory savings for a candidate boost library that abuses the preprocessor are: - 32% less SLocEntries (37M -> 25M) - 30% reduction in PCH file size (900M -> 635M) - 50% reduction in memory usage for the SLocEntry table (1.6G -> 800M) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134587 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-07Fix bug in SourceManager::getDecomposedInstantiationLocSlowCase.Argyrios Kyrtzidis
It would add up relative (decomposed) offsets like in getDecomposedSpellingLocSlowCase, but while it makes sense to preserve the offset among lexed spelling locations, it doesn't make sense to add anything to the offset of the instantiation location. The instantiation location will be the same regardless of the relative offset in the tokens that were instantiated. This bug didn't actually affect anything because, currently, in practice we never create macro locations with relative offset greater than 0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134586 91177308-0d34-0410-b5e6-96231b3b80d8
