Hello Richard, as a follow-up patch to the bit-fields patch(es), I wanted to remove the dependencies on the variable flag_strict_volatile_bitfields from expand_assignment and expand_expr_real_1. Additionally I want the access mode of the field to be selected in the memory context, instead of the structure's mode.
Boot-strapped and regression-tested on x86_64-linux-gnu. OK for trunk? Thanks Bernd. FYI - these are my in-flight patches, which would be nice to go into the GCC 4.9.0 release: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02046.html :[PATCH] reimplement -fstrict-volatile-bitfields v4, part 1/2 http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02025.html :[PATCH] Fix C++0x memory model for -fno-strict-volatile-bitfields on ARM http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02291.html : [PATCH, PR 57748] Check for out of bounds access, Part 2 http://gcc.gnu.org/ml/gcc-patches/2013-11/msg00581.html :[PATCH, PR 57748] Check for out of bounds access, Part 3 http://gcc.gnu.org/ml/gcc-patches/2013-11/msg00133.html:[PATCH] Fix PR58115

* expr.c (expand_assignment): Remove dependency on
flag_strict_volatile_bitfields. Always set the memory
access mode.
(expand_expr_real_1): Likewise.
