2016-01-06sim: sim_{create_inferior,open,parse_args}: constify argv/env slightlyMike Frysinger1-2/+3
2016-01-03 Mike Frysinger <vapier@gentoo.org> * sim-options.c (sim_parse_args): Mark argv array const. * sim-options.h (sim_parse_args): Likewise.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger1-3/+1
Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.
2015-12-30sim: h8300: inline sim_state_initializeMike Frysinger1-27/+1
All the state is handled already by the common cpu allocation which zeros out the entire state.
2015-12-30sim: h8300: simplify h8300_reg_{fetch,store} funcsMike Frysinger1-53/+17
We can leverage the cpu->regs array rather than going through the function helpers to get nice compact code. Further, fix up the return values: return -1 when we can't find a register (and let the caller write out warnings), return 2/4 when we actually write out that amount, and handle the zero reg.

2015-12-30sim: h8300: move default endian/alignment to configureMike Frysinger1-4/+0
2015-12-30sim: arm/d10v/h8300/m68hc11/microblaze/mips/mn10300/moxie/sh/v850: convert ↵Mike Frysinger1-5/+8
to common sim_{fetch,store}_register
2015-12-30sim: h8300: move unused/buggy lregs arrayMike Frysinger1-4/+0
This array isn't used anywhere, and the init phase actually corrupts some memory because the array has 18 elements but tries to set the 19th (ZERO) position.
2015-12-24sim: h8300: move h8300-specific options out of common codeMike Frysinger1-0/+54
Register the options in sim_open like other arches to avoid having to hack up the common modules.
2015-11-22sim: h8300: delete global callback/kind/nameMike Frysinger1-47/+18
We can use the sim state everywhere now to get these values on the fly.
2015-11-15sim: h8300: convert to common sim_{reason,stop}Mike Frysinger1-14/+0
This ends up being pretty easy as the h8300 port already supports much of the common engine core.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger1-6/+0
Other than the nice advantage of all sims having to declare one fewer common function, this also fixes leakage in pretty much every sim. Many were not freeing any resources, and a few were inconsistent as to the ones they did. Now we have a single module that takes care of all the logic for us. Most of the non-cgen based ones could be deleted outright. The cgen ones required adding a callback to the arch-specific cleanup func. The few that still have close callbacks are to manage their internal state. We do not convert erc32, m32c, ppc, rl78, or rx as they do not use the common sim core.
2015-11-10sim: h8300: drop unused littleendian variableMike Frysinger1-13/+0
2015-04-17sim: arm/cr16/d10v/h8300/microblaze/sh: fill out sim-cpu pc fetch/store helpersMike Frysinger1-0/+22
This makes the common sim-cpu logic work.
2015-04-15sim: cris/frv/h8300/iq2000/lm32/m32r/sh64: standardize cpu stateMike Frysinger1-1/+9
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.
2015-03-24sim: erc32/h8300/m68hc11: trim unused functionsMike Frysinger1-23/+0
These funcs are only used with the old run.o, and these sims use nrun.o, so drop these stub funcs.
2014-12-03callback.h:struct host_callback_struct compilation error on Windows hosts.Joel Brobecker1-2/+3
On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name. This patch fixes the issue by renaming the stat-related fields by adding a "to_" prefix, similar to what is done in GDB's target_ops vector. include/gdb/ChangeLog: * callback.h (struct host_callback_struct) <to_stat>: Renamed from "stat". <to_fstat>: Renamed from "fstat". <to_lstat>: Renamed from "lstat". sim/common/ChangeLog: * sim-io.c (sim_io_stat, sim_io_fstat): Adjust calls to "stat" and "fstat" callbacks by calls to "to_stat" and "to_fstat" (resp) callbacks following renaming in callback.h. * syscall.c (cb_syscall): Likewise.

2014-03-05sim: constify prog_nameMike Frysinger1-1/+1
There's no need for the prog_name handed down to the core to be mutable, so add const markings to it and all the related funcs.
2014-02-17sim: delete duplicate SIGINT handlingMike Frysinger1-14/+0
Many of the simulators change the SIGINT handler. E.g., moxie/interp.c: sigsave = signal (SIGINT, interrupt); However, this is unnecessary. remote-sim.h already provides an API for asynchronously stopping a sim; and both gdb and the drivers (run.c and nrun.c at least, I didn't check the others) install a SIGINT handler which calls this method.

2011-07-05sim: start a unified sim_do_commandMike Frysinger1-7/+0
Since sim_do_command for many people simply calls sim_args_command, start a unified version of it. For people who handle their own options, they could switch to this by using sim_add_option_table instead. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-04-14sim: constify sim_write source buffer (part 2)Mike Frysinger1-1/+1

* compile.c (decode): Enhancements for mova. Initialize cst, reg, and rdisp inside the loop, for each new instruction. Defer correction of the disp2 values until later, and then adjust them by the size of the first operand, rather than the size of the instruction. (sim_resume): For mova, adjust the size of the second operand according to the type of the first operand (INDEXB vs. INDEXW). In cases where there is only one operand, the other two must both be composed on the fly.
