Description

Over time, several intrinsic functions have been labeled archaic. See here for the complete list. They should be replaced by their modern equivalent. For example: dsin works for real, while csin and zsin for complex of different kind. They should be replaced by sin, which works for all cases.

Contributor guide

Research direction
Find all uses of archaic intrinsic functions (e.g., dsin, csin, zsin) in the Fortran codebase and replace them with their modern equivalents (e.g., sin). Refer to the GCC documentation for the complete list.
