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. From-SVN: r144924
