Bug ID: 381274
Summary: powerpc too chatty even with --sigill-diagnostics=no
about unrecognized instructions
Product: valgrind
Version: 3.13 SVN
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: vex
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Even with valgrind --sigill-diagnostics=no (or -q) guest_ppc_toIR.c will report
various cases why it didn't handle an instruction. e.g.
disInstr(ppc): found the Power 8 instruction 0x10000508 that can't be handled
by Valgrind on this host. This instruction requires a host that
supports Power 8 instructions.
After which valgrind will generate a SIGILL. But in case the user uses -q or
--sigill-diagnostics=no they aren't interested in that diagnostics. For example
openssl will try some power 8 instructions while initializing and catch the
SIGILL if not supported without issue.
Those messages should be guarded by if (sigill_diag) like the generic
decode_failure case.
