2011-03-18Add support for language-specific address spaces. On top of that,Peter Collingbourne
add support for the OpenCL __private, __local, __constant and __global address spaces, as well as the __read_only, _read_write and __write_only image access specifiers.

2011-03-18The Darwin kernel does not provide useful guard variable support.John McCall
Issue this as an IR-gen error; it's not really worthwhile doing this "right", i.e. in Sema, because IR gen knows a lot of tricks beyond what the constant evaluator knows. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127854 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-15Introduce a CharUnits FieldOffsetInChars variable in AppendField() toKen Dyck
replace some uses of FieldOffsetInBytes. The remaining uses of FieldOffsetInBytes will be replaced once NextFieldOffsetInBytes is converted to CharUnits. No change in functionality intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127641 91177308-0d34-0410-b5e6-96231b3b80d8

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

2011-03-12Propagate 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

2011-03-09Use 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

2011-03-07When 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
