From 06f445d65b44e30be072d757edb8299d239eca31 Mon Sep 17 00:00:00 2001 From: Adrian Prantl Date: Thu, 28 Apr 2016 17:21:56 +0000 Subject: Debug info: Apply an artificial debug location to __cyg_profile_func.* calls. The LLVM Verifier expects all inlinable calls in debuggable functions to have a location. rdar://problem/25818489 llvm-svn: 267904 --- clang/lib/CodeGen/CodeGenFunction.cpp | 1 + clang/test/CodeGen/instrument-functions.c | 6 +++--- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'clang') diff --git a/clang/lib/CodeGen/CodeGenFunction.cpp b/clang/lib/CodeGen/CodeGenFunction.cpp index 29a513f2bdf..0ed425ba46a 100644 --- a/clang/lib/CodeGen/CodeGenFunction.cpp +++ b/clang/lib/CodeGen/CodeGenFunction.cpp @@ -401,6 +401,7 @@ bool CodeGenFunction::ShouldInstrumentFunction() { /// instrumentation function with the current function and the call site, if /// function instrumentation is enabled. void CodeGenFunction::EmitFunctionInstrumentation(const char *Fn) { + auto NL = ApplyDebugLocation::CreateArtificial(*this); // void __cyg_profile_func_{enter,exit} (void *this_fn, void *call_site); llvm::PointerType *PointerTy = Int8PtrTy; llvm::Type *ProfileFuncArgs[] = { PointerTy, PointerTy }; diff --git a/clang/test/CodeGen/instrument-functions.c b/clang/test/CodeGen/instrument-functions.c index d80385e2239..454dc4de522 100644 --- a/clang/test/CodeGen/instrument-functions.c +++ b/clang/test/CodeGen/instrument-functions.c @@ -1,9 +1,9 @@ -// RUN: %clang_cc1 -S -emit-llvm -o - %s -finstrument-functions | FileCheck %s +// RUN: %clang_cc1 -S -debug-info-kind=standalone -emit-llvm -o - %s -finstrument-functions | FileCheck %s // CHECK: @test1 int test1(int x) { -// CHECK: __cyg_profile_func_enter -// CHECK: __cyg_profile_func_exit +// CHECK: call void @__cyg_profile_func_enter({{.*}}, !dbg +// CHECK: call void @__cyg_profile_func_exit({{.*}}, !dbg // CHECK: ret return x; } -- cgit v1.2.3
