- Organization: GCC Team, Red Hat
GCC does not apply DEBUGGER_ARG_OFFSET to an argument passed by
invisible-reference when the home of the reference is a stack slot.
This breaks some mips debuggers, GDB included.
This patch fixes this problem. I'm tempted to put it in as obviously
correct, but... Ok to install? Tested with a Red Hat-internal
variant of mips-elf that uses eabi.

* dbxout.c (dbxout_parms): Apply DEBUGGER_ARG_OFFSET to parameters
passed by invisible reference.
