Only destroy static locals if they have non-trivial destructors. This fixes a regression introduced in 2b4fa5348ee157b6b1a1af44d0137ca8c7a71573 that caused us to emit shutdown-time destruction for variables with ARC ownership, using C++-specific functions that don't exist in C implementations. 2020-01-11 07:16:15 +08:00			`// RUN: %clang_cc1 -triple x86_64-apple-macos10.15 -emit-llvm -fobjc-arc -o - %s \| FileCheck %s`

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 twelfth batch of tests being updated (the end may be in sight soon though). 2022-02-17 05:09:36 +08:00			`I *i(void) {`
