Bug ID: 433437
Summary: FreeBSD support, part 1
Product: valgrind
Version: unspecified
Platform: Other
OS: FreeBSD
Status: REPORTED
Severity: normal
Priority: NOR
Component: vex

diff in vex directory
Primarily these changes concern the nature of alignment generated signals. On
Linux, these produce SIGSEGV and n FreeBSD they produce SIGBUS.
It would be cleaner in my opinion to rename the functions to be
gen_SIGNAL_if_not_XX_aligned
gen_SIGNAL_if_not_16_aligned
etc.
and just have the different code as follows
static
void gen_SIGNAL_if_not_XX_aligned ( IRTemp effective_addr, ULong mask )
{
stmt(
IRStmt_Exit(
binop(Iop_CmpNE64,
binop(Iop_And64,mkexpr(effective_addr),mkU64(mask)),
mkU64(0)),
#if !defined(VGO_FREEBSD)
Ijk_SigSEGV,
#else
Ijk_SigBUS,
#endif
IRConst_U64(guest_RIP_curr_instr),
OFFB_RIP
)
);
}
