This code can’t be compiled.
The problem only occurs on Linux. It works normally on Windows and OSX.
----------
import core.atomic;
void main()
{
shared(size_t) count;
cas(&count, count, 0); // NG
cas(&count, count, cast(size_t)0); // OK
}
----------
The error message:
----------
/home/travis/dlang/dmd-2.079.0/linux/bin64/../../src/druntime/import/core/atomic.d(937,35): Error: bad type/size of operands mov
----------
@TurkeyMan updated dlang/druntime pull request #2745 "Renovate core.atomic, improve and simplify the constraints on functions" fixing this issue:
- Add missing features to the API.
Renovate core.atomic, improve and simplify the constraints on functions.
Most functions are slightly more efficient.
Concentrate more specific work into less surface area.
Fixes issues 20107, 20106, 20105, 18643, 15007, 8831
