2009-04-26implement PCH support for the rest of ExprObjC.h, includingChris Lattner
the missing bits of ObjCMessageExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70100 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Don't read all of the records in the PCH file's preprocessor block,Douglas Gregor
most of which are ignored. Instead, move the __COUNTER__ value out to a PCH-level record (since it is handled eagerly) and move the header file information into the SourceManager block (which is also, currently, loaded eagerly). This results in another 17% performance improvement in the Cocoa-prefixed "Hello, World" with PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70097 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Fix for PR4074: allow subscripting non-lvalue arrays in C90 mode.Eli Friedman
I wasn't originally going to use this approach, but cases like test/Sema/expr-comma.c make things difficult. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70096 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Lazily load the controlling macros for all of the headers known in theDouglas Gregor
PCH file. In the Cocoa-prefixed "Hello, World" benchmark, this takes us from reading 503 identifiers down to 37 and from 470 macros down to 4. It also results in an 8% performance improvement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70094 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25fix PR4073 by making designated initializer checking code useChris Lattner
VerifyIntegerConstantExpression instead of isIntegerConstantExpr. This makes it ext-warn but tolerate things that fold to a constant but that are not valid i-c-e's. There must be a bug in the i-c-e computation though, because it doesn't catch this case even with pedantic. This also switches the later code to use EvaluateAsInt which is simpler and handles everything that evaluate does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70081 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Revert my changes that try to avoid creating StringMap entries forDouglas Gregor
identifiers. They don't yet work, but will inhibit future optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70071 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Start implementing the PTH IdentifierInfo-saving trick in PCH,Douglas Gregor
allocating IdentifierInfos with a pointer into the string data stored in the PCH file rather than having an entry in the identifier table's string map. However, we don't actually get these savings at the moment, because we go through the IdentifierTable when loading identifiers from the on-disk hash table. This commit is for record-keeping purposes only. I'll be reverting this change (and the PCH layout tweak that preceded it) because it appears that implementing this optimization will collide with another, future optimization to reduce the size of the on-disk hash table for identifiers. That optimization is likely to provide more benefit (with less voodoo). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70070 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Write the identifier offsets array into the PCH file as a blob, soDouglas Gregor
that the PCH reader does not have to decode the VBR encoding at PCH load time. Also, reduce the size of the identifier offsets from 64 bits down to 32 bits. The identifier table itself isn't going to grow to more than 4GB :) Overall, this results in a 13% speedup in the Cocoa-prefixed "Hello, World" benchmark. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70063 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25Write the declaration and type offset arrays into the bitstream asDouglas Gregor
blobs, so that we don't need to do any work to get these arrays into memory at PCH load time. This gives another 19% performance improvement to the Cocoa-prefixed "Hello, World!". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Load the selector table lazily from the PCH file. Douglas Gregor
This results in a 10% speedup on the Cocoa-prefixed "Hello, World!", all of which is (not surprisingly) user time. There was a tiny reduction in the size of the PCH file for Cocoa.h, because certain selectors aren't being written twice. I'm using two new tricks here that I'd like to replicate elsewhere: (1) The selectors not used in the global method pool are packed into the blob after the global method pool's on-disk hash table and stored as keys, so that all selectors are in the same blob. (2) We record the offsets of each selector key when we write it into the global method pool (or after it, in the same blob). The offset table is written as a blob, so that we don't need to pack/unpack a SmallVector with its contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70055 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25This is a pretty big cleanup for how invalid decl/type are handle.Chris Lattner
This gets rid of a bunch of random InvalidDecl bools in sema, changing us to use the following approach: 1. When analyzing a declspec or declarator, if an error is found, we set a bit in Declarator saying that it is invalid. 2. Once the Decl is created by sema, we immediately set the isInvalid bit on it from what is in the declarator. From this point on, sema consistently looks at and sets the bit on the decl. This gives a very clear separation of concerns and simplifies a bunch of code. In addition to this, this patch makes these changes: 1. it renames DeclSpec::getInvalidType() -> isInvalidType(). 2. various "merge" functions no longer return bools: they just set the invalid bit on the dest decl if invalid. 3. The ActOnTypedefDeclarator/ActOnFunctionDeclarator/ActOnVariableDeclarator methods now set invalid on the decl returned instead of returning an invalid bit byref. 4. In SemaType, refering to a typedef that was invalid now propagates the bit into the resultant type. Stuff declared with the invalid typedef will now be marked invalid. 5. Various methods like CheckVariableDeclaration now return void and set the invalid bit on the decl they check. There are a few minor changes to tests with this, but the only major bad result is test/SemaCXX/constructor-recovery.cpp. I'll take a look at this next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70020 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25rename getNumParmVarDeclsFromType back to getNumParams(),Chris Lattner
remove a special case that was apparently for typeof() and generalize the code in SemaDecl that handles typedefs to handle any sugar type (including typedef, typeof, etc). Improve comment to make it more clear what is going on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70015 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24Fix rdar://6821047 - clang crashes on subscript of interface in 64-bit modeChris Lattner
Several changes here: 1. We change Type::isIncompleteType to realize that forward declared interfaces are incomplete. This eliminate special case code for this from the sizeof path, and starts us rejecting P[4] when P is a pointer to an incomplete interface. 2. Explicitly reject P[4] when P points to an interface in non-fragile ABI mode. 3. Switch the sizeof(interface) diagnostic back to an error instead of a warning in non-fragile abi mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69943 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-24Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's ↵Douglas Gregor
good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69941 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23Add implicit definition of objc_msgSend.Daniel Dunbar
- As with malloc and friends, this is important where the return type on a 64-bit platform would otherwise end up discarding the upper 32-bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69874 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23the logic for computing __func__ and friends is really broken:Chris Lattner
the type assigned by sema (and is visible with sizeof(__func__) for example) has nothing to do with what codegen ends up producing. We should eventually add a method on PredefinedExpr to handle this. In the meantime, just set up some framework and add some fixme's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69872 91177308-0d34-0410-b5e6-96231b3b80d8
