Hi,
This patch adds a GCC MIPS command line option (-mxpa) to enable/disable
support for the eXtended Physical Address (XPA) instructions within
the assembler.
The ChangeLog and patch are shown below.
Many thanks,
Andrew
* doc/invoke.texi: Document -mxpa and -mno-xpa MIPS command line
options.
* config/mips/mips.opt (mxpa): New option.
* config/mips/mips.h (ASM_SPEC): Pass mxpa and mno-xpa to the
assembler.
