There is precedent for this - change; the _other_ main loop in sis.c gets it right according to - my reading of the code. - - The bug is: if an interrupt happens when the next instruction - (at sregs->pc) is annulled, the trap is taken (by execute_trap()) - with the current values of PC and NPC, so when the trap returns, - the annulled instruction is indeed executed. Another giveaway is - that the annul flag is cleared in execute_trap(): the information - is demonstrably discarded. - - The solution is: perform annulling before looking for traps, in - fact it's neater to do annulling, see if there's an interrupt and - if not, do the instruction, then handle traps be they generated by - interrupts pending or by the instruction we might just have done. - That's what the sis.c one does. - -1999-01-20 Hugo Tyson <hmt@cygnus.co.uk> - - * sis.h: Add asr17 register for support of SparcLITE (at least the - Hitachi ones I find before me) - - * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if - sparclite. Other ASR numbers than 17 or 0 (Y) trap out. - Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto. - (execute_trap): Do single-vector-trapping if asr17 bit 0 is set. - (init_regs): Initialize y and asr17. - NB: In instruction-set space, the Y register is asr0; the - instructions have different names for human reasons only. - - * sis.c: - * interf.c: Set boolean mode variable dumbio if invoked with - argument "-dumbio" and mention it of verbose. - * erc32.c: if "dumbio" is set, do not assume that there is a - terminal type device attached to stdin/stdout. Do not set - buffering or mess with tcsetattr or do any read operations in - order to make UART interrupts; not input data is supported. - This is necessary to allow the sim to be used within the eCos - testing infrastructure where stdin/stdout are pipes to a TCL - program; the sim hangs otherwise. - -Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com> - - * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction. - -Tue Jul 7 21:12:41 1998 Mark Alexander <marka@cygnus.com> - - * func.c (bfd_load): Add special handling of a.out executables. - -Sat Jun 13 08:33:25 1998 Mark Alexander <marka@cygnus.com> - - * func.c (bfd_load): Print correct endianness. - * interf.c (run_sim): Print debugging information if verbosity level - is greater than 2. - (sim_open): Repeated -v options now increment verbosity level. - (sim_store_register): Handle little-endian case. - (flush_window): Print debugging information if verbosity level - is greater then 2. - -Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com> - - * interf.c (sim_open): Use revamped memory_read, which makes - byte-swapping unnecessary.
