Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* cpu.h (cpu_model): Add declaration.
* cpu.c (struct _cpu): Add model_ptr to hold model specific
information.
(cpu_model): Return the model internal pointer.
(cpu_{create,init,halt}): Call the appropriate model function.
* inline.c (mon.c): Move include of mon.c after model.c.
* mon.c (_cpu_mon): Add fields to count unaligned memory
references.
(mon_issue): Call model_issue, not function_unit_issue.
(mon_{read,write}): Count # of unaligned memory accesses.
(mon_print_info): Switch to calling model_mon_info and
model_mon_info_free instead of function_unit version. Print out
number of unaligned reads/writes.
* {ppc-instructions,igen.c}: More global changes to add model
specific features.
Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* Makefile.in (devices.o, main.o): Update dependency.
* igen.c (gen_model_h): Use correct variable in loop.
(gen_model_c): Use strcmp, strcasecmp.
(gen_model_{c,h}): Use STATIC_MODEL for arrays.
(gen_model_c): Use EXTERN_MODEL for arrays.
(gen_model_h): Use STATIC_MODEL for arrays.
(lf_print_c_semantic_function_header): Delete unused function.
* main.c (cpu.h): Include cpu.h to get model.h.
* inline.h (STATIC_MODEL): Define.
* inline.h ({EXTERN,STATIC}_MODEL): Define.
