Bug ID: 61653
Summary: Warning 'literal-suffix' is not suppressed by gcc
pragma
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ruslan_baratov at yahoo dot com
Suppression of warning '-Wliteral-suffix' is not working. Example:
> cat foo.cpp
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wliteral-suffix"
#define N
const char* x = "abc"N;
#pragma GCC diagnostic pop
> g++ -Wall -std=c++11 -c foo.cpp
foo.cpp:5:17: warning: invalid suffix on literal; C++11 requires a space
between literal and string macro [-Wliteral-suffix]
const char* x = "abc"N;
Clang works fine for the same code:
> cat foo.cpp
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wreserved-user-defined-literal"
#define N
const char* x = "abc"N;
#pragma GCC diagnostic pop
> clang++ -Wall -std=c++11 -c foo.cpp
# silence here
Version:
> g++ --version
