// Test 5.3.2.2: Machine ISA register test

// Misa is a specific case so I don't want to add a whole test case for reading nonzero but unkown value CSRs.
csrr x30, misa // should not cause a fault in machine mode. not writing to output because MISA is different for different configs.
li x7, 0x111 // success value for read of nonzero misa 
bnez x30, misa_nonzero
li x7, 0xbad // misa was zero, store bad value
