[PATCH 04/17] MIPS: o32: provide ta0..ta3 register definitions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This allows to write generic assembly code that will compile under both
o32 and n64 ABIs, as otherwise the register definitions would conflict.

Taken from Linux kernel sources, commit 'MIPS: O32: Provide definition
of registers ta0 .. ta3.' (3ba1e543ab4b02640d396098f2f6a199560d5f2d).
