[patch, binutils] Patch elf/mips.h for -mfp64 support.
Tue Sep 10 00:56:00 GMT 2013
We would like to enable Linux processes to use 64-bit FP registers (as
opposed to using register pairs for DP values) on 32-bit MIPS
Even though there are GNU attributes for this mode AFAICS, the GNU
attribution section is not being inspected by the Linux kernel, thus
adding a bit to the MIPS e_flag field is needed.
Is it OK if we apply the following patch so that we can proceed with
adding the support to the Linux kernel to support this mode?

* mips.h (EF_MIPS_32BITMODE): New e_flags bit.
* elfxx-mips.c check for EF_MIPS_32BITMODE, print [32bitfp64]
* readelf.c check for EF_MIPS_32BITMODE, print 32bitfp64
* tc-mips.c When it is appropriate, set EF_MIPS_32BITMODE.
