[Clang] Implement function attribute no_stack_protector. Summary: This attribute tells clang to skip this function from stack protector when -stack-protector option is passed. GCC option for this is: __attribute__((__optimize__("no-stack-protector"))) and the equivalent clang syntax would be: __attribute__((no_stack_protector)) This is used in Linux kernel to selectively disable stack protector in certain functions.

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 second batch of tests being updated (there are a significant number of other tests left to be updated). 2022-02-04 15:19:56 -05:00			`void __attribute__((no_stack_protector)) foo(void) {}`
