c++: Stream DECL_CONTEXT for template template parms [PR98881]
When streaming in a nested template-template parameter as in the
attached testcase, we end up reaching the containing template-template
parameter in 'tpl_parms_fini'. We should not set the DECL_CONTEXT to
this (nested) template-template parameter, as it should already be the
struct that the outer template-template parameter is declared on.
The precise logic for what DECL_CONTEXT should be for a template
template parameter in various situations seems rather obscure. Rather
than trying to determine the assumptions that need to hold, it seems
simpler to just always re-stream the DECL_CONTEXT as needed for now.
PR c++/98881
gcc/cp/ChangeLog:
* module.cc (trees_out::tpl_parms_fini): Stream out DECL_CONTEXT
for template template parameters.
(trees_in::tpl_parms_fini): Read it.
gcc/testsuite/ChangeLog:
* g++.dg/modules/tpl-tpl-parm-3.h: New test.
* g++.dg/modules/tpl-tpl-parm-3_a.H: New test.
* g++.dg/modules/tpl-tpl-parm-3_b.C: New test.
* g++.dg/modules/tpl-tpl-parm-3_c.C: New test.
