Bug #: 51776
Summary: fixincludes hacks around a C++ deficiency
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bk...@gnu.org
a new fixinclude hack is about to be added to paper over the fact that
g++ -std=c++11 claims full compliance, but is slightly deficient.
Once that is fixed, this new hack should be removed. It will be
approximately thus:
+/*
+ * g++ -std=c++11 defines __cplusplus to 201103L, but does not
+ * properly support [[noreturn]].
+ */
+fix = {
+ hackname = cdef_cplusplus;
+ files = sys/cdefs.h;
+ select = '\[\[noreturn\]\]';
+ c_fix = format;
+ c_fix_arg = "__attribute__((__noreturn__))";
+ test_text = "#define _Noreturn [[noreturn]]";
+};
