* David Brownell <david-b@pacbell.net>More Thumb2 disassembly:oharboe2009-08-201-2/+136
| | | | | | | | | | | | | | | ARMv7-M: A5.3.6 Load/store dual or exclusive, table branch GCC will generate the table branch instructions, usually with inlined tables that will confuse this disassembler. LDREX and STREX are not issued by GCC without inline assembly. This means all Thumb2 instructions implemented by Cortex-M3 can now be disassembled. Cortex-A8 cores support more Thumb2 instructions, but most of those aren't yet publicly documented. git-svn-id: svn://svn.berlios.de/openocd/trunk@2598 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | A5.3.11 Data processing (shifted register) The usual kinds of problems; the most noteworthy were that the "S"et flags bit was mis-handled in these instructions. --- This is the last patch from a quickie set of tests covering all encodings of the instructions with 32-bit opcodes. There may be some corner cases left, plus the instructions that aren't yet handled, but the Thumb2 disassembler is no longer just "lightly" tested with GCC output ... the new code paths have mostly been verified. git-svn-id: svn://svn.berlios.de/openocd/trunk@2568 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | A5.3.8 Load halfword, unallocated memory hints It's mostly the usual sort of bitmasking goofage and getting the width specs right.

| | | | | | | | | | | | | | | | | Make the Thumb2 disassembler handle a bunch of 32-bit instructions: A5.3.4 Branches and miscellaneous control Note that this shifts some responsabililty out of helper functions, making the code and layout simpler for 32-bit decoders: they only need to know how to format the instruction and its parameters. Also, technical note: with this patch, Thumb1 decoders could now call the Thumb2 decoder if they wanted to get nicer treatment of the exiting 32-bit B/BLX instructions. git-svn-id: svn://svn.berlios.de/openocd/trunk@2532 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | Change layout of Thumb disassembly to work better with Thumb2: - Move opcode to the left, allowing space for four hex bytes: * after address, two spaces not one tab (taking 6 spaces) * after 2-byte opcode, four spaces before tab - Also, after opcode mnemonic use a tab not a space, to make operands line up Sample output (after some patches decoding a few 32-bit instructions): 0x00003e5a 0xf4423200 ORR r2, r2, #131072 ; 0x20000 0x00003e5e 0x601a STR r2, [r3, #0x0] 0x00003e60 0x2800 CMP r0, #0x00 0x00003e62 0xd1f3 BNE 0x00003e4c 0x00003e64 0xf008fa38 BL 0x0000c2d8 The affected lines of code now wrap at sane margins too. git-svn-id: svn://svn.berlios.de/openocd/trunk@2531 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial support for disassembling Thumb2 code. This works only for Cortex-M3 cores so far. Eventually other cores will also need Thumb2 support ... but they don't yet support any kind of disassembly. - Update the 16-bit Thumb decoder: * Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added by ARMv6. (It already seems to treat CPY as MOV.) * Understand CB, CBNZ, WFI, IT, and other opcodes added by in Thumb2. - A new Thumb2 instruction decode routine is provided. * This has a different signature: pass the target, not the instruction, so it can fetch a second halfword when needed. The instruction size is likewise returned to the caller. * 32-bit instructions are recognized but not yet decoded. - Start using the current "UAL" syntax in some cases. "SWI" is renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM". - Define a new "cortex_m3 disassemble addr count" command to give access to this disassembly. Sanity checked against "objdump -d" output; a bunch of the new instructions checked out fine. git-svn-id: svn://svn.berlios.de/openocd/trunk@2530 b42882b7-edfa-0310-969c-e2dbd0fdcd60

a certain command (thanks to Andrew Dyer for this enhancement) - OpenOCD now includes the ability to diassemble instructions on its own (only ARM for now, Thumb might follow). The command is "armv4_5 disassemble <address> <count> ['thumb']" (thumb is currently unsupported). I've compared the produced disassembly against GDB/GNU Objdump output, and it seems to be correct, but there may still be some bugs left. git-svn-id: svn://svn.berlios.de/openocd/trunk@68 b42882b7-edfa-0310-969c-e2dbd0fdcd60
