More volatile musings [was: Re: [avr-gcc-list] memcpy() : problem when passing destination pointer]

[Andy Warner]

Here is a paper on the volatile performance/conformance of
various compilers (mostly gcc-based.) Including avr-gcc:

While most of the problems referred to in this thread (and all the
problems in Vincent's original posting) were programmer-induced,
the paper does talk about how the compilers can error, how to detect
it and possible workarounds.
