changeset 362875aec1ba in /z/repo/gem5 details: http://repo.gem5.org/gem5?cmd=changeset;node=362875aec1ba description: scons: Silence clang 3.4 warnings on Ubuntu 12.04
This changeset fixes three types of warnings that occur in clang 3.4 on Ubuntu 12.04: * Certain versions of libstdc++ (primarily 4.8) use struct and class interchangeably. This triggers a warning in clang. * Swig has a tendency to generate code with the register class which was deprecated in C++11. This triggers a deprecation warning in clang. * Swig sometimes generates Python wrapper code which returns uninitialized values. It's unclear if this is actually a problem (the cases might be limited to failure paths). We'll silence these warnings for now since there is little we can do about the generated code. diffstat: SConstruct | 7 ++++++- src/SConscript | 8 ++++++++ 2 files changed, 14 insertions(+), 1 deletions(-) diffs (35 lines): diff -r ef888b246cd0 -r 362875aec1ba SConstruct --- a/SConstruct Wed Aug 13 06:57:27 2014 -0400 +++ b/SConstruct Wed Aug 13 06:57:28 2014 -0400 @@ -638,7 +638,12 @@ # is relying on this main.Append(CCFLAGS=['-Wno-tautological-compare', '-Wno-parentheses', - '-Wno-self-assign']) + '-Wno-self-assign', + # Some versions of libstdc++ (4.8?) seem to + # use struct hash and class hash + # interchangeably. + '-Wno-mismatched-tags', + ]) main.Append(TCMALLOC_CCFLAGS=['-fno-builtin']) diff -r ef888b246cd0 -r 362875aec1ba src/SConscript --- a/src/SConscript Wed Aug 13 06:57:27 2014 -0400 +++ b/src/SConscript Wed Aug 13 06:57:28 2014 -0400 @@ -940,6 +940,14 @@ # with non-virtual destructors new_env.Append(CXXFLAGS=['-Wdelete-non-virtual-dtor']) + swig_env.Append(CCFLAGS=[ + # Some versions of SWIG can return uninitialized values + '-Wno-sometimes-uninitialized', + # Register storage is requested in a lot of places in + # SWIG-generated code. + '-Wno-deprecated-register', + ]) + werror_env = new_env.Clone() werror_env.Append(CCFLAGS='-Werror') _______________________________________________ gem5-dev mailing list gem5-dev@gem5.org http://m5sim.org/mailman/listinfo/gem5-dev
