Hi,

The attached patch includes the expansion of CGEN_ASM_INIT_HOOK into the 
generated code for @arch@_cgen_init_asm if it is defined. The provides 
an architecure specific hook for assembler initialization.

This will be used by the soon-to-be-contributed port for the Toshiba MeP 
architecture, but is general enough to be considered on its own.

Seeking approval to commit.

Dave
