Tue Nov 28 13:38:26 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* sim-endian.h: Look at WORDS_BIGENDIAN to determine if the host
is big endian or little endian. For SWAP_n, use htonl/htons if
host is little endian, not big endian and if WITH_NTOH is defined.
* configure{,.in} (--enable-sim-model-issue): Instead of defining
0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}.
0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}. Add
AC_C_BIGENDIAN to determine if the host is big endian or not.
* config.in: Regenerate.
* std-config.h (WITH_MODEL_ISSUE): Default to 0.
(CURRENT_MODEL_ISSUE): Reference WITH_MODEL_ISSUE, and if that is
0, use current_model_issue.
(MODEL_ISSUE_{PROCESS,IGNORE}): Define as -1/1.
* psim.c (current_model_issue): New global variable.
