Description
When passing -force-debug-info to configure, the compiler optimization flags are bypassed when doing a release build.
This can be fixed in qtbase/mkspecs/features/default_post.prf:35
force_debug_info {
QMAKE_CFLAGS_RELEASE = $$QMAKE_CFLAGS_OPTIMIZE $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
QMAKE_CXXFLAGS_RELEASE = $$QMAKE_*CFLAGS_OPTIMIZE $$QMAKE_CXXFLAGS_RELEASE_WITH_DEBUGINFO
QMAKE_OBJECTIVE_CFLAGS_RELEASE = $$QMAKE_OBJECTIVE_CFLAGS_RELEASE_WITH_DEBUGINFO
QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO
}
Andy came up with this fix. It only appears to affect OS X.
