It's tempting to just bump the timeout to 300 seconds
since anything that fails with that timeout really should
be fixed. The right thing is to pass the timeout from ptest-runner
down to valgrind's vg_regtest script. If we have people who set
timeouts to a non-default value and will be running valgrind's
ptest then I could do that.
Since I'm a completist, I'm going to try qemumips64 next! :)
Okay, so maybe I'm not a MIPS64 completist!
Let me try to help a bit.
qemumips64 hangs on drd/tests/annotate_barrier. I'm not sure why.
When run under gdb:
(gdb) bt

r = <optimized out>
__PRETTY_FUNCTION__ = "vgPlain_machine_get_hwcaps"
1905 /* MSA instructions */
1906 have_MSA = True;
1907 if (VG_MINIMAL_SETJMP(env_unsup_insn)) {
1908 have_MSA = False;
1909 }else {
1910 __asm__ __volatile__(".word 0x7800088E");/* addv.b w2, w1, w0
*/
I think its stuck executing this instruction which is checking for ASE
support and I guess we do not have ASE enabled in qemumips64 base arch
emulation, or the instruction behaves differently on 32bit and 64bit ABIs
1911 }
The qemumips64 ptests for valgrind are now on the back burner.
