60a1031181 sim: replace -I$srcroot/opcodes include with -I$srcroot
Clean up includes a bit by making ports include opcodes/ headers
explicitly.  This matches other projects, and makes it more clear
where these headers are coming from.

f51d9c6a77 sim: m32r: move arch-specific settings to internal header
There's no need for these settings to be in sim-main.h which is shared
with common/ sim code, so move it all out to the existing m32r-sim.h.
Unfortunately, we can't yet drop the m32r-sim.h include from sim-main.h
as many of the generated CGEN files refer only to sim-main.h.  We'll
have to improve the CGEN interface before we can make more progress,
but this is at least a minor improvement.

110028744c sim: lm32/m32r: drop redundant opcode/cgen.h include
The xxx-desc.h header file already includes this, and it's how the
other cgen ports are getting it, so drop it from these two.

3eaecff513 sim: cgen: move symcat.h include to where it's used
Move this out of the global sim-main.h and to the few files that
actually use functions from it.  Only the cgen ports were pulling
this, so this makes cgen & non-cgen behave more the same.

d9e217e950 sim: cgen: move cgen-types.h include to cgen-defs.h
The cgen-types.h header sets up types that are needed by cgen-defs.h,
so move the include out of sim-main.h and to that header.  It might
be needed in other specific modules, but for now let's kick it out of
sim-main.h to make some progress.  Things still build with just this.

4a21ad1e76 sim: enable common sim_cpu usage everywhere
All ports should be migrated now.  Drop the SIM_HAVE_COMMON_SIM_CPU
knob and require it be used everywhere now.

9a9db21d12 sim: m32r: invert sim_cpu storage
The cpu*.h changes are in generated cgen code, but that has been sent
upstream too, so the next regen should include it automatically.

fe41f7211a sim: m32r: unify ELF & Linux traps logic
This makes the simulator work the same regardless of the target (bare
metal m32r-elf or Linux m32r-linux-gnu) by unifying the traps code.
It was mostly already the same with the only difference being support
for trap #2 reserved for Linux syscalls.  We can move that logic to
runtime by checking the current environment operating mode instead.

f0c1b768b4 sim: move WITH_SCACHE_PBB to sim-main.h
This helps us break up tconfig.h more.  Any file using this define should
be pulling in sim-main.h already, so things should continue working.

3ebe2863f7 sim: clean up duplicate sim-engine hooks
Now that we've unified sim-cpu, we can delete the duplicate sim-engine
hooks -- these targets defined these only because they didn't fully
implement the sim-cpu callbacks.

e8d3a34fee sim: trim old USING_SIM_BASE_H define
This doesn't appear to have been used since 1998, but wasn't cleaned
up since.  So much for being "quick" ;).
2015-04-18 04:32:56 -04:00
20bca71d82 sim: unify SIM_CPU definition
Since every target typedefs this the same way, move it to the common code.

We have to leave Blackfin behind here for now because of inter-dependencies
on types and headers: sim-base.h includes sim-model.h which needs types in
machs.h which needs types in bfim-sim.h which needs SIM_CPU.
2015-04-18 04:31:36 -04:00
7e83aa92f2 sim: unify sim_cia definition
Almost every target defines sim_cia the same way -- either using the
address_word type directly, or a type of equivalent size.  The only
odd one out is sh64 (who has 32bit address_word and 64bit cia), and
even that case doesn't seem to make sense.  We'll put off clean up
though of sh64 and at least set up a sensible default for everyone.

034685f9ce sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET}
except the latter adds a layer of indirection via the sim state.  This
lets models set up different functions at runtime and doesn't reach so
directly into the arch-specific cpu state.

It also doesn't make sense to have two sets of macros that do exactly
the same thing, so lets standardize on the one that gets us more.

78e9aa70fe sim: unify sim-cpu usage
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.

f95f4ed2c4 sim: cris/frv/h8300/iq2000/lm32/m32r/sh64: standardize cpu state
This sets up the sim_state structure and the cpu member to match what we
do in most other sims, and what the common code suggests.  This is a step
to unifying on the sim-cpu.o object.
