value_type In addition, I've made the pointer and reference typedef 'void' rather than T* just so they can't get misused. I would've omitted them entirely but std::distance likes them to be there even if it doesn't use them. This rolls back r155808 and r155869.

2012-04-30Remove the ref/value inconsistency in filter_decl_iterator.David Blaikie
filter_decl_iterator had a weird mismatch where both op* and op-> returned T* making it difficult to generalize this filtering behavior into a reusable library of any kind.

2012-03-10IRgen/ABI/x86_64: Avoid passing small structs using byval sometimes.Daniel Dunbar
- We do this when it is easy to determine that the backend will pass them on the stack properly by itself. Currently LLVM codegen is really bad in some cases with byval, for example, on the test case here (which is derived from Sema code, which likes to pass SourceLocations around):: struct s47 { unsigned a; }; void f47(int,int,int,int,int,int,struct s47); void test47(int a, struct s47 b) { f47(a, a, a, a, a, a, b); } we used to emit code like this:: ... movl %esi, -8(%rbp) movl -8(%rbp), %ecx movl %ecx, (%rsp) ... to handle moving the struct onto the stack, which is just appalling. Now we generate:: movl %esi, (%rsp) which seems better, no? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152462 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Whether an argument is required (in contrast with being anJohn McCall
optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150788 91177308-0d34-0410-b5e6-96231b3b80d8
