2012-11-14When evaluating variably modified types for function parameters, dig out theEli Friedman
type as written from the ParmVarDecl; it's unclear whether the standard (C99 6.9.1p10) requires this, but we're following the precedent set by gcc, and hopefully nobody will ever ask about this again.

2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-04This patch adds a new Clang compiler flag "-gline-tables-only".Alexey Samsonov
It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.

-fno-inline-functions. This behaves much like -fno-inline in gcc, but based on a discussion with Daniel it was decided that -fno-inline-functions should subsume -fno-inline.

2012-03-01Implement "optimization" for lambda-to-block conversion which inlines the ↵Eli Friedman
generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap. Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal. With ARC, the effect is much less obvious because the lifetime of blocks is already managed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Rework the Sema/AST/IRgen dance for the lambda closure type'sDouglas Gregor
conversion to function pointer. Rather than having IRgen synthesize the body of this function, we instead introduce a static member function "__invoke" with the same signature as the lambda's operator() in the AST. Sema then generates a body for the conversion to function pointer which simply returns the address of __invoke. This approach makes it easier to evaluate a call to the conversion function as a constant, makes the linkage of the __invoke function follow the normal rules for member functions, and may make life easier down the road if we ever want to constexpr'ify some of lambdas. Note that IR generation is responsible for filling in the body of __invoke (Sema just adds a dummy body), because the body can't generally be expressed in C++. Eli, please review! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150783 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19Throw the switch to convert clang to the new exception handling model!Bill Wendling
This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140049 91177308-0d34-0410-b5e6-96231b3b80d8
