Bug#836599: shark: FTBFS on mips/mipsel: test errors

[Dejan Latinovic]

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
