GCC 7.2 is much stricter than previous GCC versions. The following changes are needed: * There is now a warning if there is an implicit fallthrough between two case statments. C++17 adds the [[fallthrough]]; declaration. However, to support non C++17 standards (i.e., C++11), we use M5_FALLTHROUGH. M5_FALLTHROUGH checks for [[fallthrough]] compliant C++17 compiler and if that doesn't exist, it defaults to nothing (no older compilers generate warnings). * The above resulted in a couple of bugs that were found. This is noted in the review request on gerrit. * throw() for dynamic exception specification is deprecated * There were a couple of new uninitialized variable warnings * Can no longer perform bitwise operations on a bool. * Must now include <functional> for std::function * Compiler bug for void* lambda. Changed to auto as work around. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82878 Change-Id: I5d4c782a4e133fa4cdb119e35d9aff68c6e2958e Signed-off-by: Jason Lowe-Power <jason@lowepower.com> Reviewed-on: https://gem5-review.googlesource.com/5802 Reviewed-by: Gabe Black <gabeblack@google.com>
