* ARM: semihosting entry cleanupDavid Brownell2009-12-041-8/+39
| | | | | | | | | Clean up arm_semihosting() entry a bit, comment some issues and just which SVC opcodes are getting intercepted. Microcontroller profile cores will need a new entry, since they use BKPT instead (and don't have either SVC mode or an SPSR register). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: remove semihosting globalsDavid Brownell2009-12-045-33/+48
| | | | | | | | Store a flag and errno in in "struct arm". Have "poll" output report when semihosting is active. Shrink some of the affected lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* basic ARM semihosting supportNicolas Pitre2009-12-034-0/+516
| | | | | | | | | | | | | | | | | | | | Semihosting enables code running on an ARM target to use the I/O facilities on the host computer. The target application must be linked against a library that forwards operation requests by using the SVC instruction that is trapped at the Supervisor Call vector by the debugger. The "hosted" library version provided with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example. This is currently available for ARM9 processors, but any ARM variant should be able to support this with little additional work. Tested using binaries compiled with Sourcery G++ Lite 2009q1-161 and ARM RVCT 3.0.

* ARMv7-A: tweak arch_state()David Brownell2009-12-031-10/+4
| | | | | | | | | Punt to the armv4_5_arch_state() for all the common stuff, to shrink code and so we will get any improvements it provides. Don't hide watchpoint status if we happen to be in "abort" mode. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: share debug reason logicDavid Brownell2009-12-037-100/+60
| | | | | | | | | | | | | | | | | | No point in both ARM11 and Cortex-A8 having private copies of the logic sorting out e.g. DBG_REASON_WATCHPOINT. Add and use a shared routine for this ... there's actually a bunch more debug entry logic that could be shared, this is just a start on that. Note that this routine fixes a bug observed in the ARM11 code, where some abort mode quirks were displayed as being an unknown debug reason; and also silences needless ARM11 chatter. Likewise with private copies of DSCR ... add one to the DPM struct. Save it as part of setting DBG_REASON_* so later patches can switch over to using that copy.

* ARM11: use shared DSCR bit namesDavid Brownell2009-12-033-42/+24
| | | | | | | | | | | | | For the bits now defined in "arm_dpm.h", switch to the shared DSCR_* symbol and remove the ARM11_DSCR_* version. Define DSCR_INT_DIS and use it instead of the ARM11_DSCR_* sibling symbol. (Note: for both ARM11 and Cortex-A8, this should arguably be enabled by default when single stepping.) Remove some other unused declarations in "arm11.h". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: make DSCR bit defs sharableDavid Brownell2009-12-033-33/+43
| | | | | | | | | | | | | | | | Move the symbols for these bits from "armv7a.h" to "arm_dpm.h", where they can be seen and used not just by Cortex-A but also by the ARM11 (armv6) code. Change them from bit numbers to bit masks ... this matches the usage in ARM11 code, and also makes it easier to read. Rename DSCR_EXT_INT_EN as DSCR_ITR_EN to match the docs; it's enabling ITR functionality, not external interrupts, so this changes the name to be less misleading. (There *IS* a bit affecting interrupts, and this isn't it.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* remove tertiary include pathsZachary T Welch2009-12-031-4/+1
| | | | | With all #include directives converted, we only need to have the top-level src/ directory in the search path.
* change #include "../hello.h" to "hello.h"Zachary T Welch2009-12-031-1/+1
| | | | | | Before we can -I the top-level src/ directory alone, references to "hello.h" must be updated. This is an internal header, so it does not need angle brackets.

* ARM11: don't expose DSCRDavid Brownell2009-12-022-185/+7
| | | | | | | | | | | Remove the remaining extra copy of DSCR, and the register cache of which it was a part. That cache wasn't a very safe, or even necessary, idea; it was essentialy letting debugger-private state be manipulated by Tcl code that couldn't know how to do it right. This makes the "reg" output of an ARM11 resemble what most other ARM cores produce ... forward motion in the "make ARM11 work like the rest of the ARM cores" Jihad!
* ARM11: store a clean copy of DSCRDavid Brownell2009-12-024-76/+56
| | | | | | | Just store a clean copy of DSCR in the per-CPU struct, so we trivially pass a pointer to a recent copy. This replaces the previous "last_dscr" and cleans up most of the related calling conventions ... but it doesn't remove the other DSCR copy.
* ARM11: don't expose WDTRDavid Brownell2009-12-022-14/+11
| | | | | | | | | Don't expose the WDTR register through the register cache any more. If anyone wants Tcl scripts to be able to use DCC based communication with app code in the target, this wouldn't do it. Bugfix: don't trust the Tcl-accessible version of DSCR to flag whether WDTR needs to be restored when resuming.
* ARM11: don't expose RDTRDavid Brownell2009-12-022-15/+11
| | | | | | | | | Don't expose the RDTR register through the register cache any more.

* ARM11: streamline debug entryDavid Brownell2009-12-021-25/+20
| | | | | | | | | | | | | Streamline arm11_on_enter_debug_state() entry: - It should handle the standard updates: * target->debug_reason * target->state - Don't waste time re-reading DSCR; just pass it in Also rename the routine to "arm11_debug_entry()", matching the convention used elsewhere in OpenOCD.
* ARM11: remove arm11->targetDavid Brownell2009-12-023-20/+12
| | | | | Don't need/want arm11->target; we have arm11->arm.target instead. Also remove some unused watchpoint stuff.
* ARM DPM: tweak initializationDavid Brownell2009-12-026-23/+33
| | | | | | Move the initial breakpoint/watchpoint disable calls to arm_dpm_initialize(), and start using that routine. This split helps with arm11 support.
* adding files required for distributionZachary T Welch2009-12-021-0/+1
| | | | | Add headers missing from Makefile rules to pass 'make distcheck'. These were included in the tree but were not added with those commits.
* fix 'target init' command registrationZachary T Welch2009-12-021-6/+6
| | | | | The command handler registration was put at the top level, rather than as a subcommand. Move it to where it belongs.
* target: factor init to 'target init'Zachary T Welch2009-12-021-0/+23
| | | | Adds 'target init' command handler, called as part of 'init'.
