sim: move many common settings from CPPFLAGS to config.h Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.

* config.in, configure: Regenerate.
sim: drop unused SIM_AC_OPTION_PACKAGES This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-11 06:49:48 +08:00
2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: allow the environment configure option everywhere Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.

2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure.ac (SIM_AC_OPTION_ENVIRONMENT): Delete call.
* configure: Regenerate.
sim: drop targ-vals.def->nltvals.def indirection We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.

* configure: Regenerate.
sim: allow the assert configure option everywhere Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.

* configure.ac (SIM_AC_OPTION_INLINE): Delete call.
* configure: Regenerate.
sim: drop --enable-sim-cflags option No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
2016-01-09 17:00:53 +08:00
2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: drop --enable-sim-{regparm,stdcall} options These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-09 18:13:37 +08:00
2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: drop common/cconfig.h in favor of a single config.h The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.
2016-01-09 09:23:37 +08:00
2016-01-09 Mike Frysinger <vapier@gentoo.org>
* config.in, configure: Regenerate.
sim: sim_{create_inferior,open,parse_args}: constify argv/env slightly 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.
2016-01-03 14:51:44 +08:00
2016-01-06 Mike Frysinger <vapier@gentoo.org>
* interp.c (sim_create_inferior): Mark argv and env const.
(sim_open): Mark argv const.
sim: aarch64: switch to common disassembler tracing The output should largely be the same.
2015-12-31 12:26:05 +08:00
2016-01-05 Mike Frysinger <vapier@gentoo.org>
* interp.c: Delete dis-asm.h include.
(info, opbuf, op_printf, aarch64_print_insn, sim_dis_read): Delete.
(sim_create_inferior): Delete disassemble init logic.
(OPTION_DISAS, aarch64_option_handler, aarch64_options): Delete.
(sim_open): Delete sim_add_option_table call.
* memory.c (mem_error): Delete disas check.
* simulator.c: Delete dis-asm.h include.
(disas): Delete.
(HALT_UNALLOC): Replace disassembly logic with TRACE_DISASM.
(HALT_NYI): Likewise.
(handle_halt): Delete disas call.
(aarch64_step): Replace disas logic with TRACE_DISASM.
* simulator.h: Delete dis-asm.h include.
(aarch64_print_insn): Delete.
sim: unify min/max macros Import defines from gdb/defs.h to the sim core so we can delete the various copies that already exist.
2016-01-05 11:24:03 +08:00
2016-01-04 Mike Frysinger <vapier@gentoo.org>
* simulator.c (MAX, MIN): Delete.
(do_vec_maxv): Change MAX to max and MIN to min.
(do_vec_fminmaxV): Likewise.
sim: aarch64: drop syscall.h include to fix build The simulator is including syscall.h which is not standard and apparently not required (builds correctly without it on my machine).
2015-12-09 19:34:45 +08:00
2016-01-04 Tristan Gingold <gingold@adacore.com>
* simulator.c: Remove syscall.h include.
sim: punt x86-specific bswap logic The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-04 17:06:01 +08:00
2016-01-04 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: drop host endian configure option The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03 13:36:13 +08:00
2016-01-03 Mike Frysinger <vapier@gentoo.org>
* configure.ac (SIM_AC_OPTION_HOSTENDIAN): Delete.
* configure: Regenerate.
sim: convert to bfd_endian Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.
2016-01-03 06:46:16 +08:00
2016-01-02 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: aarch64/msp430: fix disassembler usage The disasm framework reserves the private_data field for the disassemblers themselves, not for people who use the disassembler. Instead, there is an application_data field for callers such as the sim. Switch to it to avoid random corruption/crashes when the disassemblers use private_data.
2015-12-27 14:41:27 +08:00
2015-12-27 Mike Frysinger <vapier@gentoo.org>
* interp.c (sim_dis_read): Change private_data to application_data.
(sim_create_inferior): Likewise.
sim: unify sim-hload Pretty much all targets are using this module already, so add it to the common list of objects. The only oddball out here is cris and that's because it supports loading via an offset for all the phdrs. We drop support for that.
2015-04-11 07:40:34 +08:00
2015-12-27 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-hload.o.
sim: punt WITH_DEVICES & tconfig.h support No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
2015-12-27 09:20:23 +08:00
2015-12-26 Mike Frysinger <vapier@gentoo.org>
* config.in, configure: Regenerate.
sim: standardize sim_create_inferior handling of argv a bit more For targets that process argv in sim_create_inferior, improve the code: - provide more details in the comment - make the check for when to re-init more robust - clean out legacy sim_copy_argv code This will be cleaned up more in the future when we have a common inferior creation function, but at least help new ports get it right until then.
2015-12-26 20:05:41 +08:00
2015-12-26 Mike Frysinger <vapier@gentoo.org>
* interp.c (sim_create_inferior): Update comment and argv check.
sim: aarch64: move ChangeLog content
2015-12-26 20:12:13 +08:00
