Accumulator is present in configs with FPU and/or DSP MPY (mpy > 6) Instead of doing this in pt_regs (and thus every kernel entry/exit), this could have been done in context switch (and for user task only) as currently kernel doesn't clobber these registers for its own accord. However we will soon start using 64-bit multiply instructions for kernel which can clobber these. Also gcc folks also plan to start using these as GPRs, hence better to always save/restore them Signed-off-by: Vineet Gupta <vgupta@synopsys.com> |
