2011-09-09Bring llvm.annotation* intrinsics support back to where it was in llvm-gcc: canJulien Lerouge
annotate global, local variables, struct fields, or arbitrary statements (using the __builtin_annotation), rdar://8037476. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139423 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Carry the debug information from single exit unified return blockEric Christopher
along with the new insert point. Fixes PR10829 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139416 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-11Simplify EH control flow by observing that EH scopes form a simpleJohn McCall
hierarchy of delegation, and that EH selector values are meaningful function-wide (good thing, too, or inlining wouldn't work). 2,3d 1a hierarchy of delegation and that EH selector values have the same meaning everywhere in the function instead of being meaningful only in the context of a specific selector. This removes the need for routing edges through EH cleanups, since a cleanup simply always branches to its enclosing scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137293 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09A number of array-related IR-gen cleanups.John McCall
- Emit default-initialization of arrays that were partially initialized with initializer lists with a loop, rather than emitting the default initializer N times; - support destroying VLAs of non-trivial type, although this is not yet exposed to users; and - support the partial destruction of arrays initialized with initializer lists when an initializer throws an exception. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134784 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-24Change the IR-generation of VLAs so that we capture bounds,John McCall
not sizes; so that we use well-typed allocas; and so that we properly recurse through the full set of variably-modified types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133827 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-15Automatic Reference Counting.John McCall
Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions.

2011-04-15C1X: implement generic selectionsPeter Collingbourne
As an extension, generic selection support has been added for all supported languages. The syntax is the same as for C1X. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129554 91177308-0d34-0410-b5e6-96231b3b80d8

PHINode::Create() giving the (known or expected) number of operands. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128538 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
2011-03-07DebugInfo 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

2011-02-17Change the representation of GNU ?: expressions to use a different expressionJohn McCall
class and to bind the shared value using OpaqueValueExpr. This fixes an unnoticed problem with deserialization of these expressions where the deserialized form would lose the vital pointer-equality trait; or rather, it fixes it because this patch also does the right thing for deserializing OVEs. Change OVEs to not be a "temporary object" in the sense that copy elision is permitted. This new representation is not totally unawkward to work with, but I think that's really part and parcel with the semantics we're modelling here. In particular, it's much easier to fix things like the copy elision bug and to make the CFG look right. I've tried to update the analyzer to deal with this in at least some obvious cases, and I think we get a much better CFG out, but the printing of OpaqueValueExprs probably needs some work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125744 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17Step #1/N of implementing support for __label__: split labels intoChris Lattner
LabelDecl and LabelStmt. There is a 1-1 correspondence between the two, but this simplifies a bunch of code by itself. This is because labels are the only place where we previously had references to random other statements, causing grief for AST serialization and other stuff. This does cause one regression (attr(unused) doesn't silence unused label warnings) which I'll address next. This does fix some minor bugs: 1. "The only valid attribute " diagnostic was capitalized. 2. Various diagnostics printed as ''labelname'' instead of 'labelname' 3. This reduces duplication of label checking between functions and blocks. Review appreciated, particularly for the cindex and template bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125733 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-15Assorted cleanup:John McCall

Stmt::const_child_range, then make a bunch of places use them instead of the individual iterator accessors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125450 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-26Better framework for conditional cleanups; untested as yet.John McCall
I'm separately committing this because it incidentally changes some block orderings and minor IR issues, like using a phi instead of an unnecessary alloca. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124277 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-14When simplifying a cleanup's entry by merging it into a single predecessor,John McCall
replace all uses of the entry with the predecessor. There are no cleanups relying on this right now, but if we ever want a cleanup with a phi inside it, this will be important. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123438 91177308-0d34-0410-b5e6-96231b3b80d8
