2009-05-12push GlobalDecl through enough of the CodeGenModule interfacesChris Lattner
to allow us to support generation of deferred ctors/dtors. It looks like codegen isn't emitting a call to the dtor in member-functions.cpp:test2, but when it does, its body should get emitted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71594 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-08reimplement __sync_* builtins to be variadic and to follow the sameChris Lattner
semantic rules that gcc and icc use. This implements the variadic and concrete versions as builtins and has sema do the disambiguation. There are probably a bunch of details to finish up but this seems like a large monotonic step forward :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71212 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-08initial support for ObjC exceptions with the GNU runtime:Chris Lattner
"This patch is a first pass at adding support for exceptions for the GNU runtime. There are a few limitations at present: - @synchronized() is not yet supported at all. gcc currently emits calls to runtime library functions that don't exist for this directive. - Only id @catch statements are currently working. This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work. - I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

2009-05-05When defining a function whose type has no prototype, make an effortChris Lattner
to go back and clean up existing uses of the bitcasted function. This is not just an optimization: it is required for correctness to get always inline functions to work, see testcases in function-attributes.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70971 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Fix the field count in interface record layout (it was incorrectlyDaniel Dunbar
compensating for super classes). This was making the reported class sizes for empty classes very, very wrong. - Also, we now report the size info for an empty class like gcc (as the offset of the start, not as 0, 0). - Add a few more test cases we were mishandling before (padding bit field at end of struct, for example). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70938 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04"Fix" a problem with debug info in the presence of always_inlineChris Lattner
function calls. For a program like this: #include <stdio.h> static __inline__ __attribute__((always_inline)) int bar(int x) { return 4; } int main() { int X = bar(4); printf("%d\n", X); } clang was not outputing any debug info for the body of main(). This is because the backend is getting confused by the region_start/end that clang is emitting for block scopes. For now, just disable these (matching llvm-gcc), this stuff is in progress of rework anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70889 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Don't allow clients to traverse into superclass synthesized propertiesDaniel Dunbar
via CollectObjCIvars. - In places where we need them, we should have the implementation and access the properties through it. This is a fairly substantial functionality change: 1. @encode no longer encodes synthesized ivars, ever. 2. The ivar layout bitmap no longer encodes information for synthesized ivars in superclasses. Well, actually I had already broken that, but it is intentional now. We are now differing substantially from llvm-gcc and gcc here. However, in my opinion this fundamentally *must* work if non-fragile classes are to work. Without this change, the result of @encode and the ivar layout depend on the order that the implementation is seen in a file (if it is in the same file with its superclass). Since both scenarios should work the same, our behavior is now consistent with gcc behavior as if an implementation is never seen following an implementation of its superclass. Note that #2 is only a functionality change when (A) an implementation appears in the same translation unit with the implementation of its superclass, and (B) the superclass has synthesized ivars. My belief is that this situation does not occur in practice. I am not yet sure of the role/semantics of @encode when synthesized ivars are present... it's use is fairly unsound in a non-fragile world. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70822 91177308-0d34-0410-b5e6-96231b3b80d8
