Remove test code. Remove #if 0 code. * interp.c: Provide prototypes for all static functions. Fix minor indention problems. (sim_open, sim_resume): Remove unused variables. (sim_read): Return type is "int". * simops.c: Remove unused variables. (divh): Make result of divide-by-zero zero. (setf): Initialize result to keep compiler quiet. (sar instructions): These just clear the overflow bit. * v850_sim.h: Provide prototypes for put_byte, put_half and put_word. Cleaning up. --- diff --git a/sim/v850/ChangeLog b/sim/v850/ChangeLog index 75293ff..fa8e4d7 100644 --- a/sim/v850/ChangeLog +++ b/sim/v850/ChangeLog @@ -1,5 +1,18 @@ Tue Sep 3 10:20:30 1996 Jeffrey A Law (law@cygnus.com) + * gencode.c: Fix various indention & style problems. + Remove test code.
