On my Wii, running the frsp test results in this output:

Hello world!
Subtest 11 failed in ../cputest/frsp.cpp on line 34: frsp(0xfff7ffffffffffff, NI=0):
     got 0xffffffffe0000000
expected 0xfff7ffffe0000000
Test 1 failed (12 subtests, 1 failures)
Shutting down...

On Dolphin (with both the x64 JIT and the cached interpreter), I get this output:

Hello world!
Subtest 7 failed in ../cputest/frsp.cpp on line 34: frsp(0x380fffffffffffff, NI=1):
     got 0x3810000000000000
expected 0x0000000000000000
Subtest 11 failed in ../cputest/frsp.cpp on line 34: frsp(0xfff7ffffffffffff, NI=0):
     got 0xffffffffe0000000
expected 0xfff7ffffe0000000
Test 1 failed (12 subtests, 2 failures)

My conclusion is that the test incorrectly handles SNaN:

though Dolphin is incorrectly handling the other case (I previously linked the wrong line (the one for smallest positive single normal); this is the correct one):

This makes it harder than necessary to know these packages are missing.

Sometimes, the tev test fails.

Here's a log from real hardware (I quit partway in by pressing the HOME button): tev.txt

I don't have a consistent way of reproducing, but I've never seen it pass initially and then fail partway through; it's either consistently passing, or frequently failing. I've had this happen with #48, but also without it. (Unfortunately I'm not certain if the issue persists between builds, or happens inconsistently with the same elf file.)
