Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 -emit-llvm < %s`
Don't crash emitting an initializer for a static local with union type. This fix just makes sure to construct the global with the appropriate type, and fixes up the one user this affects to compensate. llvm-svn: 52084 2008-06-08 09:23:18 +08:00
Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the eleventh batch of tests being updated (there are a significant number of other tests left to be updated). 2022-02-16 05:06:01 +08:00			`int a(void) {static union{int a;} r[2] = {1,2};return r[1].a;}`
