2011-11-07sim: dv-cfi: check for posix_fallocateMike Frysinger5-3/+13
Some systems (like OS X) do not have posix_fallocate. Add a configure check for it before we try to use it. This is less work than trying to support old systems. URL: http://sourceware.org/bugzilla/show_bug.cgi?id=13161 Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-10-19sim: dv-cfi: check for log2 support in libm when enabledMike Frysinger14-1/+321
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>

sim/common/ChangeLog: From John Wehle <john@feith.com> (tiny patch) * sim-profile.c (profile_info): Only print the title once.
2011-10-18sim: rename common/aclocal.m4 to common/acinclude.m4Mike Frysinger55-974/+1099
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 Frysinger80-9955/+9569
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>

2011-10-10sim: dv-cfi: include stdbool.hMike Frysinger2-0/+5
The dv-cfi code uses the bool type but doesn't include the stdbool.h header. I didn't notice for Blackfin targets as the core Blackfin header will include stdbool.h, but most targets don't do this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-10sim: dv-cfi: include common headers onlyMike Frysinger2-1/+6
The "devices.h" header is Blackfin-specific, so trying to build dv-cfi for any other target fails. Include the specific hw headers this file needs directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-05sim: merge changes from common.m4 back into SIM_AC_COMMONMike Frysinger2-0/+13
Seems some fixes were added to the common.m4 file but not the SIM_AC_COMMON macro. Keep the two in sync since they're supposed to be the same thing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-09-29sim: bfin: use store buffer for VIT_MAX insnsMike Frysinger4-2/+63
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>
2011-07-12sim: include sim-options.h for command prototypeMike Frysinger2-0/+5
The sim_args_command prototype is in sim-options.h, so pull it in directly rather than assuming a common header does it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12sim: fix broken skel configure.ac exampleMike Frysinger2-1/+5
Shell code before AC_INIT will be silently culled, and since the common aclocal.m4 includes inline shell code, the file cannot be included before AC_INIT. So update the example to show people including the file after that rather than before to avoid random breakage. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12sim: use AC_REQUIRE with AC_PROG_CCMike Frysinger2-1/+6
The autoconf guys point out that our usage of AC_PROG_CC in the SIM_AC_COMMON does not jive with their intended use. http://www.gnu.org/software/autoconf/manual/autoconf.html#Expanded-Before-Required So utilize AC_REQUIRE to make the warnings go away and generate the correct code with different autoconf versions.

2011-07-05sim: start a unified sim_do_commandMike Frysinger27-182/+91
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>

2011-06-18sim: 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: 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.

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

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.

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>
