2009-02-25Temporarily disable clearing of insert point (to indicate unreachableDaniel Dunbar
code) when calling noreturn functions; general expression emission isn't ready to do the right thing in all cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65473 91177308-0d34-0410-b5e6-96231b3b80d8

- No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65470 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-25Pull COdeGenFunction::CreateStaticBlockVarDecl (just for creating theDaniel Dunbar
global variable) out of GenerateStaticBlockVarDecl. - No intended functionality change. - Prep for some mild cleanups and PR3662. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65466 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65422 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24patch for two things.Fariborz Jahanian
make sure objc2's nonfragile abi is enacted for Leopard too. add -fobjc-gc-only flag to the image_info symbol. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65413 91177308-0d34-0410-b5e6-96231b3b80d8

unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65403 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner
The big difference here is that (like string literal) @encode has array type, not pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65391 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-24Fix IRgen of constant expressions referring to external/staticDaniel Dunbar
variables. - PR3657. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65381 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Some initial Obj-C zero cost EH support.Daniel Dunbar
- Only handles cases with @try with no @catch blocks, and there are a number of problems with the implementation. Nevertheless, this is good enough to handled @synchronized correctly, and some other basic uses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65378 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Add a note about an IRgen optimization opportunity.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65376 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Prevent accidental copying of CodeGenFunction and CodeGenModule.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65372 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Pass the CodeGenModule object to GenerateBlockFunction, instead of *this ↵Anders Carlsson
(which will call the copy constructor). Also, since we're creating a new CodeGenFunction object for each block function, we don't need to clear the BreakContinueStack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65371 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Ensure that we can't break or continue out of a block.Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65370 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Fix two @synchronized bugs found by inspection: the expression to sychronize ↵Daniel Dunbar
on should only be evaluated once, and it is evaluated outside the cleanup scope. Also, lift SyncEnter and SyncExit up in nervous anticipation of x86-64 zero cost EH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65362 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Improve merging of function declarations. Specifically:Douglas Gregor
- When we are declaring a function in local scope, we can merge with a visible declaration from an outer scope if that declaration refers to an entity with linkage. This behavior now works in C++ and properly ignores entities without linkage. - Diagnose the use of "static" on a function declaration in local scope. - Diagnose the declaration of a static function after a non-static declaration of the same function. - Propagate the storage specifier to a function declaration from a prior declaration (PR3425) - Don't name-mangle "main" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65360 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-23We should not generate __weak write barrier on indirect referenceFariborz Jahanian
of a pointer to object; This patch does this odd behavior according to gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65334 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-23Add low level support for generating invoke instead of calls.Daniel Dunbar
- No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65325 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22Make sure to reset the DidCallStackSave variable before emitting a compound ↵Anders Carlsson
statement. Fixes PR3649. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65291 91177308-0d34-0410-b5e6-96231b3b80d8

true a local pointer to objective-c object in generating write barriers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65290 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65286 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65285 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22x86_64 ABI: Actually, we can always pass things we want to pass inDaniel Dunbar
memory using Indirect; this was a holdover from when CGCall wasn't as robust. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65278 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22Eliminate a bunch of code which should be dead.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65267 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22x86_64 ABI: Make sure to pass vectors that we want to pass in memoryDaniel Dunbar
as byval. Otherwise LLVM will have its own opinion about where to put things. We now pass all gcc dg.compat tests on x86_64. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65266 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22x86_64 ABI: Pass 32-bit vectors as Integer to match gcc. We don't careDaniel Dunbar
about these much but <2 x i16> shows up in the gcc test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65264 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22x86_64 ABI: Classify <1 x i64> as INTEGER (match gcc not llvm-gcc).Daniel Dunbar
Also, make sure to pass <1 x i64> as i64 (not <1 x i64>, which doesn't quite work yet in the backend). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65262 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22Last part of PR3254: use the same alignment computation in Sema and Eli Friedman
CodeGen. I'm not sure whether this actually makes any visible difference, but it's better to be consistent anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65259 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-21More work to integrate newly added ObjCQualifiedClassType into the type system.Steve Naroff
This is necessary 'plumbing' to fix <rdar://problem/6497631> Message lookup is sometimes different than gcc's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65248 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-21The blocks ABI is wrong, add a FIXME.Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65243 91177308-0d34-0410-b5e6-96231b3b80d8

clear insertion point. The rest of IRgen should theoretically take advantage of this to avoid emitting dead code. Theory != Practice. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65141 91177308-0d34-0410-b5e6-96231b3b80d8
