<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Oliver Hunt (ojhunt) <details> <summary>Changes</summary> The change made in #<!-- -->162433 exposed a weakness in this test that showed different results on different archs that were not caught on the CI bots. This expands the tests to cover more archs, and out of necessity moves the os_log test into a separate test file. --- Patch is 83.30 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/168319.diff 2 Files Affected: - (added) clang/test/CodeGen/builtin-os_log.c (+414) - (modified) clang/test/CodeGen/builtins.c (+315-681) ``````````diff diff --git a/clang/test/CodeGen/builtin-os_log.c b/clang/test/CodeGen/builtin-os_log.c new file mode 100644 index 0000000000000..7ded5133d48e0 --- /dev/null +++ b/clang/test/CodeGen/builtin-os_log.c @@ -0,0 +1,414 @@ +// REQUIRES: x86-registered-target +// RUN: %clang_cc1 -emit-llvm -triple x86_64-darwin-apple -o - %s | FileCheck %s --check-prefixes=CHECK + + +// Removed from builtins.c as the behavior of __builtin_os_log differs between +// platforms, so we only test on X86 however having this embedded in builtins.c +// makes testing more obtuse for non-X86 dependent behaviours. + +// CHECK-LABEL: define{{.*}} void @test_builtin_os_log +// CHECK: (ptr noundef %[[BUF:.*]], i32 noundef %[[I:.*]], ptr noundef %[[DATA:.*]]) +void test_builtin_os_log(void *buf, int i, const char *data) { + volatile int len;
