Summary: Standard library does not mark functions as pure Product: D Version: 2.022 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: bugzi...@digitalmars.com ReportedBy: jason.james.ho...@gmail.com I hit this in std.cpuid, but I bet it occurs in many more places. Obviously, any part of phobos/druntime which does not properly mark pure functions is unusable from pure code. I'm pretty sure that the cpuid never changes while a program is running and the various attribute querying and toString should be pure. --
