* atomics: Fix the win32 atomic_exchange functionMartin Storsjö2021-04-04
| | | | | | | | | | This fixes building with MSVC after a2a38b160620d91bc3f895dadc4501c589998b9c. Remove the stray semicolon, and add casts for the input argument (which is an intptr_t*) to the right type (PVOID volatile *). Signed-off-by: Martin Storsjö <martin@martin.st>

| * compat/atomics: add typecasts in atomic_compare_exchange_strong()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Solaris and Windows emulations of atomic_compare_exchange_strong() need typecasts to avoid compiler warnings, because the functions they call expect a void* pointer but an intptr_t integer is passed. Note that the emulations of atomic_compare_exchange_strong() (except the gcc version) only work for atomic_intptr_t because of the type of the second argument (|expected|). See http://en.cppreference.com/w/c/atomic: _Bool atomic_compare_exchange_strong( volatile A* obj, C* expected, C desired ); The types of the first argument and second argument are different (|A| and |C|, respectively). |C| is the non-atomic type corresponding to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is intptr_t. This implies |A| can only be sig_intptr_t. Signed-off-by: Wan-Teh Chang <wtc@google.com>
