* Add a 'count' field to the DWARF subrange.Bill Wendling2012-12-042-1/+17
| | | | | | | | | | The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169219 91177308-0d34-0410-b5e6-96231b3b80d8

* Merge function types in C.Rafael Espindola2012-11-291-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Among other differences, GCC accepts typedef int IA[]; typedef int A10[10]; static A10 *f(void); static IA *f(void); void g(void) { (void)sizeof(*f()); } but clang used to reject it with: invalid application of 'sizeof' to an incomplete type 'IA' (aka 'int []') The intention of c99's 6.2.7 seems to be that we should use the composite type and accept as gcc does. Doing the type merging required some extra fixes: * Use the type from the function type in initializations, even if an parameter is available. * Fix the merging of the noreturn attribute in function types. * Make CodeGen handle the fact that an parameter type can be different from the corresponding type in the function type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168895 91177308-0d34-0410-b5e6-96231b3b80d8
