Hello,
Running Linux 6.17.7 on a Power Mac G5, CPU POWER4 970MP, LLVM 21.1.4
When trying to run lp_test_arit from mesa project, it shows:
`altivec doesn't support nan return nan behavior`
`
round.v1(-0.5): ref = -0, out = -1, precision = -inf bits, FAIL
round.v1(0.5): ref = 0, out = 1, precision = -inf bits, FAIL
`
would it be related to float->int conversion when rounding?
Best regards,
Link.
