--- Comment #17 from Sandra Loosemore <sandra at codesourcery dot com> --- Updated patch series: http://gcc.gnu.org/ml/gcc-patches/2013-09/msg02057.html http://gcc.gnu.org/ml/gcc-patches/2013-09/msg02058.html http://gcc.gnu.org/ml/gcc-patches/2013-09/msg02059.html Unfortunately, it seems that fixing bugs with -fstrict-volatile-bitfields has been blocked by disagreement between global reviewers and target maintainers who can't agree on whether the C/C++11 memory model should take precedence over target-specific ABIs by default. :-(
