From f122a138e39dbb29162abfa9a3d44091d8efa7af Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Wed, 13 Jun 2012 20:27:03 +0000 Subject: Add -isystem-prefix and -ino-system-prefix arguments, which can be used to override whether headers are system headers by checking for prefixes of the header name specified in the #include directive. This allows warnings to be disabled for third-party code which is found in specific subdirectories of include paths. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158418 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Frontend/system-header-prefix.c | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 test/Frontend/system-header-prefix.c (limited to 'test/Frontend/system-header-prefix.c') diff --git a/test/Frontend/system-header-prefix.c b/test/Frontend/system-header-prefix.c new file mode 100644 index 0000000000..31194d96e5 --- /dev/null +++ b/test/Frontend/system-header-prefix.c @@ -0,0 +1,11 @@ +// RUN: %clang_cc1 -isystem-prefix libs/ -ino-system-prefix libs/mylib/ -I%S/Inputs/SystemHeaderPrefix -Wundef -E %s 2>&1 | FileCheck %s + +#include "src/all.h" + +// CHECK-NOT: BOOST +// CHECK: libs/mylib/warn.h:1:5: warning: 'MYLIB' is not defined, evaluates to 0 +// CHECK-NOT: BOOST +// CHECK: libs/mylib/warn.h:1:5: warning: 'MYLIB' is not defined, evaluates to 0 +// CHECK-NOT: BOOST +// CHECK: src/warn.h:1:5: warning: 'SRC' is not defined, evaluates to 0 +// CHECK-NOT: BOOST -- cgit v1.2.3-18-g5258
