; This is included from crt0.S for a.out, as we can't have it as
; a separate object file in a library due to the lack of named
; section support and the required placement at address 3*4.

; We define an interrupt table with references to the symbols
; _.irq_XX where XX are hex numbers 3..ff (lower-case).  They
; are satisfied by weak aliases to the _.irq stub function in
; this file.  When overridden, the overriding function must be
; in code explicitly linked in, i.e. *not* in a library.

; No use having a separate file with default _.irq_[0-f][0-f]
; definitions; just provide a single stub with a weak definition
; and make it up to the user to provide a strong definition that
; they force to be linked in (i.e. not in a library or at least
; together with another symbol they know is linked in).
