1831 unexpectedly. For more information please refer to the gas
1832 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1834 Loongson 2F03 and later have fixed these issues and no workarounds
1835 are needed. The workarounds have no significant side effect on them
1836 but may decrease the performance of the system so this option should
1837 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1838 systems.
