Short version:
Compiling a file with -mv6443 produces code for TMS320C64xx architecture.
Since DM6443 supports C64x+, I would have expected code for TMS320C64x+.
Is this a compiler bug?
Longer version:
Compiling for 6443:
$ ~/c6_6.1.22/bin/cl6x -k -mv6443 irq.c
gives irq.asm:

Compiling this (that use c64x+ only intructions):
#####
int x;
int main()
{
asm(" DINT");
x++;
asm(" RINT");
return x;
}

with 6443 fails:
