ada: Static intrinsic functions are a core language extension.
GNAT-defined Ada extensions are divided into two categories: those that are
enabled by either -gnatX or -gnatX0 and those which require -gnatX0.
Move static intrinsic functions from the second category into the first.
gcc/ada/
* doc/gnat_rm/implementation_defined_pragmas.rst: Add the standard
'... "On" enables this extension.' sentence to the description of
static intrinsic functions.
* sem_ch13.adb
(Analyze_Aspect_Spec): In the call to Error_Msg_GNAT_Extension for
a Static aspect specification for an intrinsic function, specify
Is_Core_Extension => True.
* sem_eval.adb
(Eval_Intrinsic_Call): Test Core_Extensions_Allowed instead of
testing All_Extensions_Allowed.
* gnat_rm.texi: Regenerate.
