From: Philippe Mathieu-Daudé <[email protected]> Per the release 6.06 revision history:
5.03 August 21, 2013 • ABS2008 and NAN2008 fields of Table 5.7 “FCSR RegisterField Descriptions” were optional in release 3 and could be R/W, but as of release 5 are required, read-only, and preset by hardware. The P5600 core implements the release 5, and has the ABS2008 and NAN2008 bits set in CP1_fcr31. Therefore it is able to run ELF binaries compiled with EF_MIPS_NAN2008, such the CIP United Debian NaN2008 distribution: http://repo.oss.cipunited.com/mipsel-nan2008/README.txt In order to run such compiled binaries, select by default the P5600 core when the ELF 'MIPS_NAN2008' flag is set.
