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>

2013-06-17sim: bfin: drop RET[ENI] setupMike Frysinger2-3/+4
Since these insns run in usermode, there should be no need to setup RET[ENI] to safe values. They won't be dereferenced, and any insn that returns via them are valid only in supervisor mode. Since this is in the main exception code path, saving any insn at all is good as it gets multiplied quickly (as in O(n^2) times). 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 Frysinger76-337/+1802
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.
2013-05-15sim: arm: add support for MOVW and MOVT instructionsMike Frysinger4-4/+71
From: Jayant R. Sonar <Jayant.Sonar@kpitcummins.com> This patch adds simulator support for handling the armv7 instructions 'movw (immediate)' and 'movt'. Compiler frequently use these instructions to load the 32bit addresses of global variables, string pointers etc. into the general registers. In absence of support of these instructions: 1. GDB run simulator fails to print even simple "hello world" string on console. 2. Loading of global variable addresses into the registers fail causing arithmetic operation failures. Patch has been regression tested for arm-none-eabi (-march=armv7-a).

2013-03-31sim: frv/m32r: back out hard failure when dv-sockser is not availableMike Frysinger9-42/+34
These sims have optional support for the dv-sockser model, so do not make them hard failures. The Makefile made it seem like they didn't actually support things dynamically, but a further code dive into the source and the Makefile shows that things work out.
2013-03-26sim: rewrite SIM_AC_OPTION_HARDWARE a bit to simplify thingsMike Frysinger23-354/+448
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.
