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....
