This allows reading and writing of SPRs via GDB: (gdb) p/x $srr1 $1 = 0x8000000002803033 (gdb) p/x $pvr $2 = 0x4b0201 (gdb) set $pvr=0x4b0000 (gdb) p/x $pvr $3 = 0x4b0000 They can also be shown as a group: (gdb) info reg spr Signed-off-by: Fabiano Rosas <farosas@linux.ibm.com> --- target/ppc/translate_init.inc.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
