[spu] Fix single-stepping regression
Switching spu_software_single_step to use a regcache instead of a frame:
https://sourceware.org/ml/gdb-patches/2016-11/msg00355.html
cause a serious regression to SPU single-stepping.
There were two separate problems:
- SPU_LSLR_REGNUM is a pseudo register, so we must use the "cooked"
regcache methods instead of the "raw" ones to access it.
- When accessing a branch target register, we must only use the first
four bytes of the 16-byte vector register. This was done automatically
by the frame routines, but not by the regcache routines.
gdb/ChangeLog:
2017-11-26 Ulrich Weigand <uweigand@de.ibm.com>
* spu-tdep.c (spu_software_single_step): Access SPU_LSLR_REGNUM as
"cooked" register. Access only first four bytes of branch target
registers.
