target-tilegx: Decode ill pseudo-instructions
Notice raise and bpt, decoding the constants embedded in the nop addil instruction in the x0 slot. [rth: Generalize TILEGX_EXCP_OPCODE_ILL to TILEGX_EXCP_SIGNAL. Drop validation of signal values.] Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Message-Id: <1443243635-4886-1-git-send-email-gang.chen.5i5j@gmail.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
