Hello list,
I was trying to do some debugging in bug [1071656].
But for some reason I receive with arm64
in a process running with valgrind
and one without valgrind different results
from the following floating point instruction:
=> 0xaaaaaaaa4948 <ConvertToRational+104>: fcvtas w5, d8
With plain GDB:
(gdb) print $w5
$2 = 323
With valgrind+GDB:
(gdb) print $w5
$2 = 322
And therefore the CI run fails and led to this bug [1071656] (at least with arm64).
I was trying this first in a qemu arm64 VM on amd64,
but could observe this on real arm64 hardware too.
Is there some knowledge about such an issue, or how to avoid this?
Kind regards,
Bernhard
