Subject: [gcc r13-1420] [Ada] Adjust description of Pure_Function pragma
Date: Mon,  4 Jul 2022 07:49:41 +0000 (GMT)	[thread overview]

    [Ada] Adjust description of Pure_Function pragma
    
    The current wording can be read as implying that the result of a call
    to a pure function does not depend on the context, which is incorrect.
    The pragma only guarantees the absence of side effects of such a call.
    
    gcc/ada/
    
            * doc/gnat_rm/implementation_defined_pragmas.rst (Pure_Function):
            Fix ambiguous wording about context dependence.
            * gnat_rm.texi: Regenerate.
