markup_oops.pl: fix error with x86
When I try to use markup_oops.pl in x86, I always get:
cat 1 | perl markup_oops.pl ./vmlinux
objdump: --start-address: bad number: NaN
No matching code found
This is because in line:
if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}
$func_offset will get a number like "0x2"
But in follow code:
my $decodestart = Math::BigInt->from_hex("0x$target") -
Math::BigInt->from_hex("0x$func_offset");
It add other ox to ox2. Then this value will be set to NaN.
So I made a small patch to fix it.
