Is a bug in CTEST?

[yinqingw]

in test_csr.c:

CTEST(core, icache)
{
    EnableICache();
    ASSERT_NOT_EQUAL(__RV_CSR_READ(CSR_MCACHE_CTL) & CSR_MCACHE_CTL_IE, 0);
    DisableICache();
    ASSERT_EQUAL(__RV_CSR_READ(CSR_MCACHE_CTL) & CSR_MCACHE_CTL_IE, 0);
}

should do

__RWMB();
__FENCE_I();

before EnableICache();andEnableICache();? Now，If my compilation option is -02,CPU may be abnormal。

Sorry, I cannot repeat it, could you provide more details for what cpu you are using, and changes you have made?

Tested on nx900fd and n900fd with -O2.

It is a possible trouble，you could only run

EnableICache();
DisableICache();
EnableICache();
DisableICache();
EnableICache();
DisableICache();

for enable and disable icache。It may have appeared.

Still works.
