1998-02-03IGEN - Replace IMEM (IMEM_IMMED) macro with IMEM<insn-size> macro,Andrew Cagney2-2/+7
update v850, tic80 and mips simulators. IGEN - Prepend prefix to more generated symbols and macros (idecode_issue, instruction_word). IGEN - Add -Wnowith option to supress warnings about word size inflicts in input files. MIPS - Clean up Makefile.in, m16.igen, m16.dc (new), m16run.c (new) so that a mips16 simulator built using IGEN can be compiled.
1998-02-02Add support for configuring the size of the floating point unit (fp_word).Andrew Cagney1-0/+4
For mips, move fp_registers into a separate array of type fp_word[].
1998-01-31Add config support for the size of the target address and OF cell.Andrew Cagney2-71/+96
1998-01-31igen: Fix SMP simulator generator support.Andrew Cagney2-1/+7
Use the bfd-processor name in the sim-engine switch. Add nr_cpus argument to sim_engine_run. tic80, v850, d30v, mips, common: Update mips: Fill in bfd-processor field of model records so that they match ../bfd/archures.

1998-01-20* aclocal.m4: Recognize --enable-maintainer-mode.Doug Evans2-52/+80
*/configure: Regenerated.
1997-12-15In nrun.c, look for sigaction & SA_RESTART. When both present,Andrew Cagney3-56/+60
install cntrl-c (SIGINT) handler with no SA_RESTART bit set.
1997-12-04Regenerate configure files.Doug Evans2-52/+101
1997-11-24 * cpu.h (TRACE_COND_BR): Use TRACE_BRANCH_P, not TRACE_ALU_P.Doug Evans2-1/+5
1997-11-22Clarify meaning of sim_signalled's SIGRC argument. Document that thisAndrew Cagney5-14/+22
isn't possible in sim-reason.c and just return the target SIGRC instead. For simulators that rely on sim-reason.c, replace SIG* with SIM_SIG*. Hack nrun.c so that when it is executed (ARGV[0]) as `step' instead of `run' it single steps the simulator. Allows testing of single step without full GDB.
1997-11-18 * sim-main.h (CIA_ADDR): Define.Doug Evans3-14/+12
* Makefile.in (SIM_OBJS): Use $(SIM_NEW_COMMON_OBJS).

1997-09-22Simplify logic behind the generic configuration option --enable-sim-alignment.Andrew Cagney2-20/+39
1997-09-22Add support for --enable-sim-alignment to simulator common aclocal.m4Andrew Cagney2-19/+38
Add support for --alignment={strict,nonstrict,forced} to simulator common run-time options. For v850 use, make the default NONSTRICT_ALIGNMENT.
