git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127617 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-14__clear_cache() is varargs and people will occasionally write it withoutEric Christopher
arguments. Process only the arguments that people write, but process all of them. Fixes rdar://8900346 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127616 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-14Fix link of libxul with LTO and the linker in xcode4. It is not clear if thisRafael Espindola
is working around a bug in ld or if the new linker has a reasonable reason for wanting the string constant to be linker visible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127594 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-13Instead of storing an ASTContext* in FunctionProtoTypes with computed ↵Sebastian Redl
noexcept specifiers, unique FunctionProtoTypes with a ContextualFoldingSet, as suggested by John McCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127568 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-12Use CharUnits for argument passed to AppendPadding() from AppendBitField().Ken Dyck
No change in functionality intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127538 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-12Propagate the new exception information to FunctionProtoType.Sebastian Redl
Change the interface to expose the new information and deal with the enormous fallout. Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications. Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127537 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-11Use a slightly more semantic interface for emitting call arguments.John McCall

2011-03-11Add support for the OpenCL vec_step operator, by generalising andPeter Collingbourne
extending the existing support for sizeof and alignof. Original patch by Guy Benyei. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127475 91177308-0d34-0410-b5e6-96231b3b80d8

avoid converting to bits and back again. No change in functionality intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127455 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-10lib/CodeGen/CGCall.cpp: Don't invoke multiple Builder.CreateBitCast() on ↵NAKAMURA Takumi
Builder.CreateMemCpy. Or we would see sideeffect incompatibility among gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127405 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127324 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Fix three of the four places where I left breadcrumbs to avoid unnecessaryJohn McCall
recomputation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127322 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Tame this assert, hopefully fixing self-host.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127319 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Use the "undergoes default argument promotion" bit on parameters toJohn McCall
simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127314 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-08Emit block capture initializers as if they were normal initializers for a localJohn McCall
variable that just happens to be stored in a wierd place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127235 91177308-0d34-0410-b5e6-96231b3b80d8

for a local variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-08Fixed source range for all DeclaratorDecl's.Abramo Bagnara
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127225 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07When we adjust the inline ASM type, we need to take into account an earlyBill Wendling
clobber with the 'y' constraint. Otherwise, we get the wrong return type and an assert, because it created a '<1 x i64>' vector type instead of the x86_mmx type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127185 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07CodeGenFunction::GenerateBlockFunction() should initialize DebugInfo just ↵Devang Patel
like CodeGenFunction::GenerateCode() git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127174 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07DebugInfo can be enabled or disabled at function level (e.g. using an ↵Devang Patel
attribute). However, at module level it is determined by command line option and the state of command line option does not change during compilation. Make this layering explicit and fix accidental cases where the code generator was checking whether module has debug info enabled instead of checking whether debug info is enabled for this function or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127165 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07Do not emit stop point for CXXDefaultArgExpr. It results in suboptimial user ↵Devang Patel
experience. 21 int main() { 22 A a; For example, here user would expect to stop at line 22, even if A's constructor leads to a call through CXXDefaultArgExpr. This fixes ostream-defined.exp regression from gdb testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127164 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07The conditional needs to be pushed before the branch. Make the test lessJohn McCall
trivial to check this. Adjust for style. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127151 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07An operator new with an empty exception specifier returns null on a badJohn McCall
allocation and therefore requires a null-check. We were doing that, but we weren't treating the new-initializer as being conditionally executed, which means it was possible to get ill-formed IR as in PR9298. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127147 91177308-0d34-0410-b5e6-96231b3b80d8

corner cases like the one in PR9301." which caused PR9416. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127136 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Emit a stop point before a call expression so that debugger has some chance ↵Devang Patel
of getting some footing when user wants to stop at 2nd bar() in following expression when all function calls are inlined. = bar() + ... + bar() + ... clang keeps track of column numbers, so we could put location entries for all subexpressions but that will significantly bloat debug info in general, but a location for call expression is helpful here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127018 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Make AttributedTypes for GC-qualified types and fix some miscellaneousJohn McCall
bugs with such types. Not sure this is quite how I want the desugaring and a.k.a. logic to go, but it suffices. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126986 91177308-0d34-0410-b5e6-96231b3b80d8

The prototype for objc_msgSend() is technically variadic - `id objc_msgSend(id, SEL, ...)`.
