src/sys/arch/mips/mips: fp.S
Log Message:
Resurrect silently removed lines in rev 1.37 that update FPU_CSR
in double's inexact or overflow cases.
Now the following tests are passed:
---
tp-start: t_except, 6
tc-start: masked_double
tc-end: masked_double, passed
:
tc-start: masked_long_double
tc-end: masked_long_double, passed
:
tp-start: t_subnormal, 2
tc-start: test_double
tc-end: test_double, passed
---
The following ones still fail:
---
tp-start: t_except, 6
:
tc-start: unmasked_double
tc-se:*** Check failed: /usr/src/tests/lib/libc/ieeefp/t_except.c:269: sicode
!= t->sicode
tc-end: unmasked_double, failed, 1 checks failed; see output for more details
tc-start: unmasked_float
tc-se:*** Check failed: /usr/src/tests/lib/libc/ieeefp/t_except.c:269: sicode

tc-end: unmasked_float, failed, 1 checks failed; see output for more details
tc-start: unmasked_long_double

tp-end: t_except
:
tp-start: t_subnormal, 2

tc-start: test_float
tc-end: test_float, failed, Test program received signal 4 (core dumped)
tp-end: t_subnormal

- t_except unmasked failures are mentioned in PR port-mips/35327.
- t_subnormal float failure seems trap caused by a FP insn in BDslot
(I'm not sure if we can use TF_REG_CAUSE in trapframe to see BD bit)
