mv -f .deps/jm_insns-jm-insns.Tpo .deps/jm_insns-jm-insns.Po
The testcase also fails:
jm-vmx: valgrind ./jm-insns -a
*** jm-vmx failed (stdout) ***
The warnings are about mfvscr %r10 and vor %r6.
Which come from the following asm statements:
__asm__ __volatile__ ("mfvscr %0" : "=vr" (tmpvscr));
__asm__ __volatile__ ("vor %0,17,17" : "=vr" (vec_out));
It looks to me that the constraints are wrong on those.
The "=vr" should probably be "=v".
