The C99 standard states:
"In the abstract machine, all expressions are evaluated as specified
by the semantics. An actual implementation need not evaluate part
of an expression if it can deduce that its value is not used and
that no needed side effects are produced (including any caused by
calling a function or accessing a volatile object)."...

In the post below, 'copy constructor?', the answers refer to
an object declared as const volatile. Now I'm confused.
Are those terms not mutually exclusive?
const='Hey compiler! This is not going to change so generate
your code based on that assumption.'
volatile='Hey compiler! This is going to change so generate
your code based on that...

Hi -
I am actually trying to get my feet in multi-threaded C++
programming. While I am aware that the C++ standard does not talk
about threads (at least, for now - in C++03) - my question is more
about the language / usage rather than any thread specific question.
Sorry - if posted my mistake.
I understand that in C++ volatile objects (...

Hello everyone.
Recently I stumbled upon an interesting problem related to thread-parallel
programming in C (and similarily C++). As an example assume a simple "buffer"
array of size 8, e.g. with static lifetime and exteral linkage. One thread fills
the buffer structure, and the other in some way evaluates its contents, e.g.
do {...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
