================
Comment at: clang/lib/CodeGen/CodeGenFunction.cpp:757-760
+ bool HaveSanitizeCoverage =
+ CGM.getCodeGenOpts().SanitizeCoverageType ||
+ CGM.getCodeGenOpts().SanitizeCoverageIndirectCalls ||
+ CGM.getCodeGenOpts().SanitizeCoverageTraceCmp;
----------------
consider adding method into CodeGenOptions and replace here and and the rest
ideally in a separate patch
================
Comment at: clang/test/CodeGen/sanitize-coverage.c:23-87
+static inline __attribute__((__always_inline__)) void always_inlined_fn(int n) {
+ if (n)
+ x[n] = 42;
+}
+// CHECK-LABEL: define dso_local void @test_always_inline(
+void test_always_inline(int n) {
+ // CHECK-DAG: call void @__sanitizer_cov_trace_pc
----------------
you are adding tests for unrelated code.
Could you please land is as a separate NFC patch first?
================
Comment at: llvm/lib/AsmParser/LLLexer.cpp:674
KEYWORD(nounwind);
+ KEYWORD(no_sanitize_coverage);
KEYWORD(null_pointer_is_valid);
----------------
looking at the rest, seems "nosanitize_coverage" follows pattern better :)
