Hello,
I took a look at this issue.
The reason of an illegal instruction is related to ldxc1 instruction.
> ldxc1 $f0,v0(a1)
> (gdb) p/x $a1
> $50 = 0xaaa8ae10
> (gdb) p/x $v0
> $51 = 0xaaaf0248
The address (a1+v0) seems to be valid and aligned to 8, but causes error anyway.
I will investigate this issue further.
This behavior is triggered by O2 optimization level. If O1 is used, this issue
will not appear.
I have created patch that enables O1 flag for failing tests.
Also it was needed to mark ObjFunct_SvmLogisticInterpretation as slow as this
test failed with timeout (1500) on my local build.
Both patches are attached.
Regards,
Dejan
