Add configury for mips-lsi-elf target (32 bit MIPS16).
Fix numerous problems with PENDING_* code. In old gencode simulator, don't double tick each cycle. Add BREAK instruction to MIPS16 gencode simulator.

|
||||
|
||||
* gencode.c (build_instruction - BREAK): For MIPS16, handle BREAK
|
||||
insn as a debug breakpoint.
|
||||
|
||||
* sim-main.h (PENDING_SLOT_BIT): Fix, was incorrectly defined as
|
||||
pending.slot_size.
|
||||
(PENDING_SCHED): Clean up trace statement.
|
||||
(PENDING_SCHED): Increment PENDING_IN and PENDING_TOTAL.
|
||||
(PENDING_FILL): Delay write by only one cycle.
|
||||
(PENDING_FILL): For FSRs, write fmt_uninterpreted to FPR_STATE.
|
||||
|
||||
* sim-main.c (pending_tick): Clean up trace statements. Add trace
|
||||
of pending writes.
|
||||
(pending_tick): Fix sizes in switch statements, 4 & 8 instead of
|
||||
32 & 64.
|
||||
(pending_tick): Move incrementing of index to FOR statement.
|
||||
(pending_tick): Only update PENDING_OUT after a write has occured.
|
||||
|
||||
* configure.in: Add explicit mips-lsi-* target. Use gencode to
|
||||
build simulator.
|
||||
* configure: Re-generate.
|
||||
|
||||
* interp.c (sim_engine_run OLD): Delete explicit call to
|
||||
PENDING_TICK. Now called via ENGINE_ISSUE_PREFIX_HOOK.
