* Solaris does not provide atomic_sub familyNobuyoshi Nakada2020-04-261-1/+1

* Clarified return value of atomic macrosNobuyoshi Nakada2020-04-261-13/+56

* Removed phony atomic operations for void* and VALUENobuyoshi Nakada2020-04-201-32/+4

* Bail out if no atomic operation foundNobuyoshi Nakada2020-04-201-24/+1
| | | | | As atomic operations are mandatory now, not-working phony fallback definitions are not only useless but confusing and harmful.
* fine-grained #ifdef guard for Sparc systems卜部昌平2020-02-061-1/+1
| | | | | | | | | There are cases when sizeof(int) == sizeof(long) == sizeof(size_t). On such cases however int and long are incompatible types in theory. We should not assume typedef long size_t, because on Solaris size_t is actually a typedef of int. This reduces compiler warnings on such situations.
* add several __has_something macro卜部昌平2019-12-261-3/+3
| | | | | | | With these macros implemented we can write codes just like we can assume the compiler being clang. MSC_VERSION_SINCE is defined to implement those macros, but turned out to be handy for other places. The -fdeclspec compiler flag is necessary for clang to properly handle __has_declspec().
