The window underflow trap handler used %i5 which destroyed the %o5 of the calling context. Bug introduced by0d3b5d4742. Go back to the pre0d3b5d4742behaviour and use the two unused instructions in the trap vector to optimize a bit. Close #2651.
This is the README file for libcpu. This directory contains reusable libraries which are CPU dependent but not target board dependent. For example, the PowerPC has an on CPU decrementer register which may be used by all PowerPC BSP's for the Clock and Timer Drivers. Other examples include the caching support for the m68k CPU models and MIPS CPU model exception vectoring routines. This level of support will make it easier for others developing embedded applications on a given CPU.
