Did 'Big endian MIPS' refer to 32-bit, or both 32 & 64-bit ? I'm guessing
it was only 32-bit BE, given the heading of your removed-features.txt
change.
Both.
* 7.2 deprecated:
- 32-bit big endian MIPS host
- 64-bit big endian MIPS host
Not deprecated remaining:
- 32-bit little endian MIPS host
- 64-bit little endian MIPS host
* 9.2 deprecated:
- 32-bit little endian MIPS host
Not deprecated remaining:
- 64-bit little endian MIPS host
* 11.0 deprecated:
- 64-bit little endian MIPS host
No non-deprecated MIPS host remaining
As of 11.0 we can remove what was deprecated previous 10.1.
But then did "MIPS since 11.0" refer to 64-bit little endian only, or
both big & little endian for 64-bit ?
Given the wide variety of things all ambiguously called "MIPS",
its worth being explicit....
