2011-07-05sim: start a unified sim_do_commandMike Frysinger1-10/+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>
2011-02-14sim: punt zfree()Mike Frysinger1-3/+3
The sim keeps track of which allocations are zero-ed internally (via zalloc) and then calls a helper "zfree" function rather than "free". But this "zfree" function simply calls "free" itself. Since I can see no point in this and it is simply useless overhead, punt it. The only real change is in hw-alloc.c where we remove the zalloc_p tracking, and sim-utils.c where zfree is delete. The rest of the changes are a simple `sed` from "zfree" to "free". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-04-14sim: constify sim_write source buffer (part 2)Mike Frysinger1-1/+1
As pointed out by Sandra Loosemore, a bunch of targets define sim_write themselves instead of using the common/ code. So constify them too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-01-18Cannot build mips simulator on darwin.Joel Brobecker1-2/+0
Masaki Muranaka <monaka@monami-software.com> (tiny change) * interp.c: Don't include sysdep.h
2007-09-04* interp.c (options enum): Add OPTION_INFO_MEMORY.Nick Clifton1-0/+45
(display_mem_info): New static variable. (mips_option_handler): Handle OPTION_INFO_MEMORY. (mips_options): Add info-memory and memory-info. (sim_open): After processing the command line and board specification, check display_mem_info. If it is set then call the real handler for the --memory-info command line switch.
2007-02-19 * interp.c (sim_monitor): Flush stdout and stderr file descriptorsThiemo Seufer1-0/+4
after each call to sim_io_write.
2007-02-19 (ColdReset): Set CP0 Config0 to reflect the address size supportedThiemo Seufer1-4/+53
by this simulator. (decode_coproc): Recognise additional CP0 Config registers correctly.
2007-02-19 * cp1.c (value_fpr): Don't inherit existing FPR_STATE forThiemo Seufer1-24/+136
uninterpreted formats. If fmt is one of the uninterpreted types don't update the FPR_STATE. Handle fmt_uninterpreted_32 like fmt_word, and fmt_uninterpreted_64 like fmt_long. (store_fpr): When writing an invalid odd register, set the matching even register to fmt_unknown, not the following register. * interp.c (sim_open): If STATE_MEM_SIZE isn't set then set it to the the memory window at offset 0 set by --memory-size command line option. (sim_store_register): Handle storing 4 bytes to an 8 byte floating point register. (sim_fetch_register): Likewise for reading 4 bytes from an 8 byte register. (sim_monitor): When returning the memory size to the MIPS application, use the value in STATE_MEM_SIZE, not an arbitrary hardcoded value. (cop_lw): Don' mess around with FPR_STATE, just pass fmt_uninterpreted_32 to StoreFPR. (cop_sw): Similarly. (cop_ld): Pass fmt_uninterpreted_64 not fmt_uninterpreted. (cop_sd): Similarly. * mips.igen (not_word_value): Single version for mips32, mips64 and mips16.
