2013-06-24sim: bfin: note missing parallel handling of SEARCHMike Frysinger2-0/+18
The SEARCH insn is an oddball when it comes to parallel usage. It places a big limit on what other insns it can run in parallel with, but we don't currently track the amount of state needed to verify this (since no other insn really requires this). Add a note for now in case we get around to it.
2013-06-24sim: bfin: handle invalid HLs encoding in dsp shift insnsMike Frysinger2-5/+16
For many of the 32bit dsp shift related insns, we were just ignoring the HLs field. The hardware does not though and will reject the insn if it's set incorrectly. Update the sim to match.
2013-06-19sim: bfin: stricter insn decodingMike Frysinger2-50/+86
We wrote a test case that tries every single 32bit opcode on the hardware and compared it to the sim. There were a bunch of places in the sim where we weren't strict enough (requiring certain parts of the opcode be set) so we were treating a lot of invalid opcodes as valid ones. This sprinkles out a lot additional checks in the dsp32alu class. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2013-06-10sim: bfin: only regen linux-fixed-code.h in maintainer modeMike Frysinger2-1/+6
Since many people don't have a Blackfin toolchain available, only try to regenerate the header file when in maintainer mode. This file rarely changes, and when it does, we commit the generated output, so there's almost never a need to run directly on an end system.
2013-06-05sim: use AM_MAINTAINER_MODEMike Frysinger3-13/+72
I noticed the sim code is using an old implementation of the maintainer logic. I cut it over to the new macro (like gdb has been doing). In practice, it makes no difference currently as nothing in the sim tree uses it, but I have a follow up commit for the Blackfin tree that needs it.

2013-03-26sim: rewrite SIM_AC_OPTION_HARDWARE a bit to simplify thingsMike Frysinger3-32/+87
There's no need to put the majority of the logic into the 3rd arg of the AC_ARG_ENABLE. Coupled with the lack of indentation, it makes it hard to follow, error prone to update, and duplicates code (with the 4th arg). So pull the logic out of the 3rd arg and outside of the AC_ARG_ENABLE macro. This allows us to gut the 4th arg entirely, merge with the code that followed the macro, and fix bugs related to the new dv-sockser in the process. Hopefully building the various sims with the default sim-hardware settings, as well as with explicit --{dis,en}able-sim-hardware flags, should all just work now.

2012-06-15Define PACKAGE macro in all sims' config.h.Joel Brobecker3-0/+19
Some of the common includes in include/gdb such as callback.h include bfd.h. But there was a recent change in bfd-in.h to require that config.h be included before bfd.h can be included: /* PR 14072: Ensure that config.h is included first. */ #if !defined PACKAGE && !defined PACKAGE_VERSION #error config.h must be included before this header #endif PACKAGE_VERSION is always defined by default by the AC_INIT autoconf macro, but PACKAGE isn't.

2012-04-09sim: bfin: new PINT modelMike Frysinger7-1/+386
Newer BF54x parts feature an updated GPIO block where all the interrupt handling is split off, so create a new model for the pin interrupts. This is missing the port forwarding aspects, but at least the register interface should be there. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-04-09sim: bfin: fix ASTAT/correctness issues with arithmetic shiftsMike Frysinger2-10/+67
This improves some of the arithmetic shifts to better match the hardware (especially wrt ASTAT behavior). We hit areas where the published documentation is thin so we have to rely on tests run on the hardware to figure out how things should behave.

2012-04-09sim: bfin: more parallel insn checksMike Frysinger2-18/+84
Now that we keep track of the exact parallel insn slot we're in, we can make sure that the current insn being decoded is valid for that slot. This brings us much closer to the hardware in flagging invalid parallel insn combinations. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-09sim: bfin: keep track of the exact position of parallel insnsMike Frysinger3-44/+75
Some insns need to know which slot they're in to determine whether they are valid. So add an enum for each slot, and check that rather than the overall insn len. This makes tracking things in the code much clearer. However, this code is functionally the same, so a follow up patch will leverage this more to properly flag invalid parallel insn combos. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-08sim: bfin: drop excess space in negation insnMike Frysinger2-1/+5
The amod1 helper includes a leading space so it can expand into the empty string when need be, which means the caller need not add spacing itself. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-01sim: bfin: throw VEC_ILGAL_I with 32bit insn in group1/group2 slotsMike Frysinger2-0/+8
Parallel insns can only do one 32bit, then two 16bits. So if we see a 2nd 32bit insn after the first 32bit in a parallel insn, abort. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-03-24[PATCH] sim: make sure to include strsignal prototypeMike Frysinger4-150/+267
Before POSIX standardized strsignal(), old systems would hide the prototype unless the normal extension defines were enabled. So use the AC_USE_SYSTEM_EXTENSIONS helper for that. Then make sure we include string.h ourselves in nrun.c rather than relying on implicit includes via other sim headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-19sim: bfin: fix corner case Logical shift issuesMike Frysinger2-45/+64
From: Robin Getz <robin.getz@analog.com> Overflow with shift operations happens independently of saturation, but we have the logic merged. Extend the lshift function so that callers can tell it when to handle each independently, and then do so when it's needed.

2011-12-03sim: bfin: lookup target strings when tracing system callsMike Frysinger2-10/+41
Parsing target addresses is hard if not generally useless, so use the new cb_get_string function to lookup the associated strings as well. Now the trace output is quickly useful instead of just marginally so. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-12-03sim: generate build dependencies on the flyMike Frysinger4-34/+306

2011-10-18sim: rename common/aclocal.m4 to common/acinclude.m4Mike Frysinger4-8/+18
Automake likes to dump macros automatically used into the aclocal.m4 file, but the common/aclocal.m4 naming prevents that. So rename it to the more normal "acinclude.m4" so the aclocal tool can work. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-18sim: move from common.m4 to SIM_AC_COMMONMike Frysinger3-364/+353
Now that the sourceware tree generally requires autoconf-2.64, update the sim tree to require that too. This allows us to drop the long standing SIM_AC_COMMON/common.m4 workaround as autoconf 2.64+ seems to work for me. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-09-29sim: bfin: use store buffer for VIT_MAX insnsMike Frysinger2-2/+6

2011-07-05sim: start a unified sim_do_commandMike Frysinger2-7/+4
