Subject: ada: Fix spurious error on imported generic function with precondition
X-Git-Tag: basepoints/gcc-15~8786
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fb828af5933219d95f0f6a98567c09813de2dde1;p=thirdparty%2Fgcc.git

ada: Fix spurious error on imported generic function with precondition

It occurs during the instantiation because the compiler forgets the context
of the generic declaration.

gcc/ada/

	* freeze.adb (Wrap_Imported_Subprogram): Use Copy_Subprogram_Spec in
	both cases to copy the spec of the subprogram.
