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 issues in immediate shiftsMike Frysinger2-17/+64
More ASTAT directed fixes, but this time at the dsp32shift insns. Signed-off-by: Robin Getz <robin.getz@analog.com> 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>
2012-04-01sim: bfin: simplify field width processing and fix build warningsMike Frysinger2-10/+6
This fix the build time warning: warning: format not a string literal, argument types not checked [-Wformat-nonliteral] Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-01sim: bfin: fix unused bfrom handling for BF535Mike Frysinger2-1/+5
machs.c: In function 'bfin_model_cpu_init': machs.c:1657:1: warning: 'bfrom' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-01sim: bfin: fix build warning/style with auxvt_sizeMike Frysinger2-2/+7
Fix warning about mixing decls and code by moving auxvt_size decl down to the scope where it is used. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-31sim: bfin: fix typo in BF54x SIC initMike Frysinger2-1/+5
The current code triggers a warning: dv-bfin_sic.c: In function 'bfin_sic_finish': dv-bfin_sic.c:930:41: warning: operation on 'sic-><U78e8>.bf54x.iwr1' may be undefined [-Wsequence-point] This points out the IWR2 register was not being setup because of a typo. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-31sim: bfin: include devices.h to fix build warningsMike Frysinger2-0/+5
The place where these funcs get defined do not include the header that declares their prototypes. Add that to fix -Wmissing-prototypes: devices.c:59:1: warning: no previous prototype for 'dv_bfin_mmr_invalid' devices.c:66:1: warning: no previous prototype for 'dv_bfin_mmr_require' devices.c:99:1: warning: no previous prototype for 'dv_bfin_mmr_check' devices.c:159:14: warning: no previous prototype for 'dv_get_bus_num' 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. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-19sim: bfin: ebiu_amc: push down hardcoded base addressesMike Frysinger2-2/+12
To make it easier to support ebiu banks at other addresses, move the base to a runtime parameter rather than structure. Future work will make this more dynamic, but I'm waiting for more details first. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-19sim: bfin: use ARRAY_SIZEMike Frysinger2-1/+6
Rather than hardcode the constant, use ARRAY_SIZE to get it. Should be no functional changes here. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sim: bfin: drop old linux/mii.h workaroundsMike Frysinger5-23/+35
We had some workarounds for old linux/mii.h headers, but it breaks with newer ones. So tweak the checks a bit to work with newer ones. We'll worry about older systems once someone complains. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

gdb/ChangeLog: Copyright year update in most files of the GDB Project.
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
Lift the code that GDB is using to generate dependencies on the fly and port it over to the sim. Now people shouldn't have to manually maintain these in their Makefile's. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-19sim: dv-cfi: check for log2 support in libm when enabledMike Frysinger2-0/+52
The dv-cfi model uses log2() internally, so make sure we automatically link in libm when required. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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
The VIT_MAX insns can be used in parallel, so we need to use the store buffer so we don't clobber the output register before we get a chance to do a memory store with it. Reported-by: Kai Iskratsch <kai@stella.at> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-05sim: start a unified sim_do_commandMike Frysinger2-7/+4
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>
2011-07-01sim: bfin: implement stat_map for virtual environments (libgloss)Mike Frysinger2-4/+30
The stat syscalls cannot work without a stat map, so declare one that matches libgloss for virtual environments. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-22sim: bfin: pass up result2/errcode with libgloss syscallsMike Frysinger2-2/+7
Now that the Blackfin libgloss code extracts the 2nd result and the error code from the R1/R2 registers, have the sim fill them up. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: set ASTAT AV/AVS when shifting accumulators overflowMike Frysinger2-0/+12
The LSHIFT/ASHIFT insns that work with accumulators lacked AV/AVS handling in the ASTAT register, so add it to match the hardware. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: do not touch ASTAT[V] when shifting accumulatorsMike Frysinger2-3/+9
If we're shifting accumulators, we don't want to touch the V bit in ASTAT, so add size checks to the ashiftrt/lshiftrt helpers. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: do not extend accumulator in LSHIFT insnsMike Frysinger2-1/+6
The logical shift insn does not sign extend before shifting, so we shouldn't either. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: tweak saturation handling with TFU/FU modes and MM bitMike Frysinger2-14/+35
This too should have been squashed into an earlier change. It covers a few more cases in the V/VS saturation patch when working with TFU and FU modes of dsp insns. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: handle large shift values with accumulator shift insnsMike Frysinger2-2/+14
When the shift magnitude exceeds 32 bits, the values rotate around (since the hardware is actually a barrel shifter). So handle this edge case, update the corresponding AV bit in ASTAT which was missing previously, and tweak the AZ setting based on how the hardware behaves. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: handle odd shift values with shift insnsMike Frysinger2-7/+36
The shift magnitude is a 5-bit signed value. When it is between 0 and 15, then we do the requested shift, but when it is outside of that, we have to do the opposite. That means we flip between lshift and ashiftrt to match the hardware. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: fix M_IH saturation sizeMike Frysinger2-17/+6
This reverts the previous commit and does it right. This change got lost in the shuffle of patches I have pending. Basically the logic is to change the 32bit saturation (and then masked to 16bits) to a proper 16bit saturation.

2011-06-18sim: bfin: handle V/VS saturation in dsp mac insnsMike Frysinger2-25/+58
Some saturation cases with dsp mac insns were not setting the V flag. So implement that part and split up the logic between the dual macs. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: handle the MM flag in M_IU/M_TFU modes with dsp insnsMike Frysinger2-0/+10
Our handling of the M_IU/M_TFU modes are missing signed saturation when the MM flag is set, so add it to match the hardware behavior. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: fix sign extension in dsp insns with MM flagMike Frysinger2-8/+10
After testing the hardware with all the different dsp flags, the MM flag triggers sign extension in all modes. So drop the limited use of it, and the local custom helper that was also extending unsigned values. We also can see that the flag checks in the mult/mac insns have the same behavior with sign extending, so add a helper func to keep the logic the same in both places. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: fix dsp insns IH saturation/rounding behaviorMike Frysinger2-1/+16
When using the IH modifier, we need to first saturate the value before rounding it, and then further saturate it a bit more. This makes the sim match the hardware behavior with these insns. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-06-18sim: bfin: fix accumulator edge case saturationMike Frysinger2-2/+7
When the accumulator saturates, it needs to be greater than, but not equal to, the largest unsigned value as this is what the hardware does. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-18sim: bfin: use freeargv for freeing argvsMike Frysinger2-1/+5
Since the argv array was allocated with dupargv, it needs to be freed with freeargv to avoid leaks. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-04sim: bfin: add support for glued SIC interrupt linesMike Frysinger2-25/+71
The BF537 family glues a bunch of peripherals into single interrupt lines that run into the SIC. To model this same behavior in the sim, we need to use the glue-or device, and in order to use that, we need to tweak things a bit in the mach code to allow declaring of these new devices. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-04sim: bfin: push SIC mappings to device treeMike Frysinger3-589/+723
The machs.c file is the best place for holding cpu-specific details, so restructure the way the SIC manages its ports to do just that. Now the SIC's have a standard set of input pins and the different line routing from peripherals is kept in the device tree only. This better models the hardware where the SIC doesn't care about the exact peripheral that is sending it stuff, just which input pin it gets it on. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-06-03sim: bfin: dma: fix indentationMike Frysinger2-1/+5
2011-05-26sim: bfin: switch to new syscall trace levelMike Frysinger2-1/+5
Now that the common code supports the syscall trace level, change the Blackfin code from using the event level to the syscall level. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-25sim: bfin: move model data into machs.hMike Frysinger31-109/+80
Pull the model data (register addresses/sizes) out of the different model files and into the machs.h header. The models themselves don't care about where they're mapped, only the mach code does. This allows us to keep the model headers from being included in the mach code which can cause issues with model-specific names colliding. Such as when a newer device model is created, but with incompatible register names/layouts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-25sim: bfin: add a performance monitor stubMike Frysinger7-0/+196
No counters get updated, but there is enough here for software to poke things and work. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-25sim: bfin: add bf526-0.2/bf54x-0.4 rom regionsMike Frysinger6-0/+27
Add regions for the on-chip roms on some newer Blackfin parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-14sim: bfin: allow pushing of SPMike Frysinger2-2/+6
The hardware respects this insn, and some code (like the on-chip bootrom) uses it, so allow it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
