2011-02-14opcodes: blackfin: fix styleMike Frysinger1-43/+42
Non-functional thrashing to the GNU style. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-14opcodes: blackfin: catch invalid loopsetup insnsMike Frysinger1-0/+3
The LoopSetup insn is only valid when the reg field is 0-7, so don't go decoding it incorrectly when reg is 8-15. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-13opcodes: blackfin: fix decoding of ABSMike Frysinger1-1/+1
The single cycle dual mac ABS insn was incorrectly decoding the mac1 part of the insn. Once we fix the decode, update the gas tests to have the correct output. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-13opcodes: blackfin: fix decoding of dsp mult insnsMike Frysinger1-2/+2
When assigning to a register half, the mac0 part of the mult insn was not decoding properly. It would always show a full dreg instead of the dreg low half. Once we fix the disassembler, we have to update a few of the gas tests as their previous expected output was incorrect. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-13gas/opcodes: blackfin: punt BYTEOP2M insn supportMike Frysinger1-68/+0
The BYTEOP2M insn was part of the initial Blackfin designs, but never made it into any actual silicon. So punt support for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-12opcodes: blackfin: add missing space after PRNT insnMike Frysinger1-1/+1
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-12opcodes: blackfin: drop "GP" registerMike Frysinger1-3/+3
There never was a "GP" register, so punt it from the decode map. It's a hold over from a very old processor definition and never made it into actual silicon. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-12gas/opcodes: blackfin: move dsp mac func defines to common headerMike Frysinger1-10/+0
The mmod field is decoded in a few places (gas/opcodes/sim), so move it to a common place to avoid duplication. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-11opcodes: blackfin: constify register namesMike Frysinger1-17/+18
Constify the array itself since it need not be writable. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-15gas: blackfin: fix encoding of BYTEOP2M insnMike Frysinger1-8/+8
The BYTEOP2M parser incorrectly calls BYTEOP2P to generate the opcode. Once we've fixed that, it's easy to see that the disassembler also likes to decode this insn incorrectly. So fix that and then add some tests. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: fix decoding of 32bit addresses on 64bit systemsMike Frysinger1-0/+3
The Blackfin ISA is very exact with regards to address truncation when under/over flowing its 32bit range. On a 32bit system, things work the same and so addresses are decoded properly. On a 64bit system though, the decoded addresses may include the bits that are supposed to have been truncated. So force a 32bit truncation after the address has been calculated. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: fix decoding of all register move insnsMike Frysinger1-12/+30
Many register move insns were not being decoded properly, so rewrite the whole function to be a bit more manageable in terms of valid combinations. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: fix decoding of many invalid insnsMike Frysinger1-21/+105
The Blackfin disassembler was originally based on the premise of parsing valid opcodes all the time, so some of the opcode checking can be a bit fuzzy. This is exemplified in decoding of parallel insns where many times things are decoded as invalid when in reality, they may not be used in parallel combinations. So add parallel checking to most insn decoding routines so we see ILLEGAL and not just whatever insn happens to be close to a valid mnemonic, as well as some additional sub-opcode checks. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: mark push/pop insns with a P6/P7 range as illegalMike Frysinger1-0/+3
The push/pop multiple insn has a 3 bit field for the P register range, but only values of 0...5 are valid (P0 - P5). There is no such P6 or P7 register, so mark these insns as illegal. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: fix decoding of vector shift insn w/saturationMike Frysinger1-1/+1
The saturation bit was missed when decoding a vector shift insn leading to the output looking the same as the non-saturating insn. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: decode all ASTAT bitsMike Frysinger1-8/+21
All ASTAT bits work in the hardware even though they aren't part of the official Blackfin ISA. So decode every ASTAT field to make the output a bit nicer when working with hand generated opcodes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: decode insns with invalid register as illegalMike Frysinger1-14/+19
Sometimes the encoding in the opcode is a 4 bit field which defines a register number. However, register numbers are only 0-7, so make sure we call illegal for when the opcode register number is greater than 8. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22gas: blackfin: fix DBG/DBGCMPLX insn encodingMike Frysinger1-1/+1
Some extended registers when given to the DBG/DBGCMPLX pseudo insns are not encoded properly. So fix them, fix the display of them when being disassembled, and add testcases. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes/gas: blackfin: handle more ASTAT flagsMike Frysinger1-4/+10
Support a few more ASTAT bits with the standard insns that operate on ASTAT bits directly. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes/gas: blackfin: support OUTC debug insnMike Frysinger1-4/+17
The disassembler has partial (but incomplete/broken) support already for the pseudo debug insn OUTC, so let's fix it up and finish it. And now that the disassembler can handle it, make sure our assembler can output it too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: fix decoding of LSHIFT insnsMike Frysinger1-2/+2
The Blackfin ISA does not have a "SHIFT" insn, it has either LSHIFT, ASHIFT, or BXORSHIFT. So be specific when disassembling. As fall out of this change, we need to update some assembler tests. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-09-22opcodes: blackfin: constify formatting related structuresMike Frysinger1-22/+22
No need for these local structures related to formatting of output to be writable, so constify the whole shebang. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
