decl.c (grokfndecl): Set DECL_CONTEXT on parms.
cp/:
* decl.c (grokfndecl): Set DECL_CONTEXT on parms.
(duplicate_decls): Adjust DECL_CONTEXT of newdecl's parms.
* pt.c (check_explicit_specialization): Likewise.
(tsubst_copy) [PARM_DECL]: Return a dummy parm if we don't have a
local specialization.
* tree.c (cp_tree_equal) [PARM_DECL]: Check type and index, not name.
* decl2.c (parm_index): New fn.
* semantics.c (finish_decltype_type): Don't use describable_type.
* mangle.c (write_expression): Likewise. Mangle ALIGNOF_EXPR.
Give a sorry for unsupported codes rather than crash. Mangle
conversions with other than 1 operand. New mangling for PARM_DECL.
* operators.def (ALIGNOF_EXPR): Mangle as az.
* include/demangle.h (enum demangle_component_type): Add
DEMANGLE_COMPONENT_FUNCTION_PARAM.
* libiberty/cp-demangle.c (d_make_function_param): new fn.
(cplus_demangle_mangled_name): Work around abi v2 bug.
(d_expr_primary): Likewise.
(cplus_demangle_operators): Add alignof ops.
(d_expression): Handle function parameters and conversions
with other than 1 operand.
(d_print_comp): Handle function parameters. Fix bug with
function used in type of function.
