RISC-V, by convention, only has four. Because RISC-V's implementation of these indices is as arrays of integers rather than as base indices plus offsets, trying to get the fifth argument register's value will cause a crash. This patch fixes that by returning 0 for any index higher than 3. Signed-off-by: Jason Lowe-Power <jason@lowepower.com> |
