There were some fixes back on March 13th, 2014 for fixing compiling on MIPS64. Also some fixes on June 25th, 2014 for SPARC64 fixes. Probably more things, but those are what I care about.

/**
|
|
* Error code layout.
|
|
*
|
|
* Currently we try to keep all error codes within the negative space of 16
|
|
* bytes signed integers to support all platforms (-0x0000 - -0x8000). In
|
|
* addition we'd like to give two layers of information on the error if
|
|
* possible.
|
|
*
|
|
* For that purpose the error codes are segmented in the following manner:
|
|
*
|
|
* 16 bit error code bit-segmentation
|
|
*
|
|
* 1 bit - Sign bit
|
|
* 3 bits - High level module ID
|
|
* 5 bits - Module-dependent error code
|
|
* 7 bits - Low level module errors
|
|
*
|
|
* For historical reasons, low-level error codes are divided in even and odd,
|
|
* even codes were assigned first, and -1 is reserved for other errors.
|
|
*
|
