* check.c (gfc_check_kill_sub): Remove check for INTEGER(4) or (8).
* intrinsic.c (add_functions): Remove reference to gfc_resolve_kill.
(add_subroutines): Remove reference to gfc_resolve_kill_sub.
* intrinsic.texi: Update documentation.
* iresolve.c (gfc_resolve_kill, gfc_resolve_kill_sub): Remove.
* trans-decl.c (gfc_build_intrinsic_function_decls): Add
gfor_fndecl_kill and gfor_fndecl_kill_sub
* trans-intrinsic.c (conv_intrinsic_kill, conv_intrinsic_kill_sub): new
functions.
(gfc_conv_intrinsic_function): Use conv_intrinsic_kill.
(gfc_conv_intrinsic_subroutine): Use conv_intrinsic_kill_sub.
* trans.h: Declare gfor_fndecl_kill and gfor_fndecl_kill_sub.
