| | | | | | | | | | | | | commit 50d5441e2a615fb2c44b41a777e4373901f7a2e6 caused native windows build to fail. Firstly this patch fixes the build issue, but it also disables support for named pipes under Windows. Windows does not support posix named pipes.

* xscale: check that wp length does not exceed addressMike Dunn2010-09-201-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi everyone, A while back I sent in a patch that adds support for watchpoint lengths greater than four on xscale. It's been working well, until the other day, when it caused an unexpected debug exception. Looking into this I realized there is a case where it breaks: when the length arg is greater than the base address. This is a consequence of the way the hardware works. Don't see a work-around, so I added code to xscale_add_watchpoint() to check for and disallow this combination. Some more detail... xscale watchpoint hardware does not support a length directly. Instead, a mask value can be specified (not to be confused with the optional mask arg to the wp command, which xscale does not support). Any bits set in the mask are ignored when the watchpoint hardware compares the access address to the watchpoint address. So as long as the length is a power of two, setting the mask to length-1 effectively specifies the length. Or so I thought, until I realized that if the length exceeds the base address, *all* bits of the base address are ignored by the comaparator, and the watchpoint range effectively becomes 0 .. length. Questions, comments, criticisms gratefully received. Thanks, Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
* xscale: bp/wp: additional LOG_ERROR on failureMike Dunn2010-09-201-6/+10
| | | | | | | | | | | | | | | | | | | | | Hi everyone, Added more LOG_ERROR messsages to watchpoint and breakpoint code, given that the infrastructure no longer interprets returned error codes. Also changed existing LOG_INFO and LOG_WARNING to LOG_ERROR for cases where an error is returned. Note that the check of the target state is superflous, since the infrastruture code currently checks this before calling target code. Is this being reconsidered as well? Also, should we stop returning anything other than ERROR_OK and ERROR_FAIL? Comments gratefully received. Thanks, Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com>

* xscale: fix sw breakpoints for thumb; set bp immediatelyMike Dunn2010-09-131-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi everyone, Version 2 of this patch. Code added to breakpoints.c was removed from previous patch, and item 3 added, per discussion with Øyvind regarding error reporting. Item 4 added, which I just noticed. I tried to use a software breakpoint in thumb code on the xscale for the first time recently, and was surprised to find that it didn't work. The result was this patch, which does four things: 1): fix trivial cut-n-paste error that caused thumb breakpoints to not work 2): call xscale_set_breakpoint() from xscale_add_breakpoint() 3): log error on data abort in xscale_write_memory() 4): fixed incorrect error code returned by xscale_set_breakpoint() when no breakpoint register is available; added comment Item 2 not only makes the xscale breakpoint code consistent with other targets, but also alerts the user immediately if an error occurs when writing the breakpoint instruction to target memory (previously, xscale_set_breakpoint() was not called until execution resumed). Also, calling xscale_breakpoint_set() as part of the call chain starting with handle_bp_command() and propagating the return status back up the chain avoids the situation where OpenOCD "thinks" the breakpoint is set when in reality an error ocurred. Item 3 provides a helpful message for a common reason for failure to set sw breakpoint. This was thoroughly tested, mindful of the fact that breakpoint management is somewhat dicey during single-stepping. Comments and criticisms of course gratefully received.

* propagate return status of set_breakpoint() up call chainMike Dunn2010-09-133-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Hi everyone, I figured since I was poking around in the breakpoint code on other arches, I'd add this change to those arches that don't do it already. This patch propagates the return code of <arch>_set_breakpoint() up the call stack. This ensures that the higher layer breakpoint infrastructure is aware that an error ocurred, in which case the breakpoint is not recorded. Normally I wouldn't touch code that I can't test, but the code is very uniform across architectures, and the change is rather benign, so I figured after careful inspection that it is safe. If the maintainers or others think this is imprudent, the patch can be dropped. Also changed the error code to something more appropriate in two cases where hardware resources are unavailable. Comments and criticisms of course gratefully received. Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

| | | | | | | | | | | | | | | | | | | | | | Commands that output progress output and no return value will have the progress output captured. Commands that do not output progress output(tcl commands) will return the tcl return value instead.

Example #1: capture progress output: set foo [capture help] Example #2: capture tcl return value set foo [capture {set abc def}] Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* xscale: mark xscale registers invalid on debug entryMike Dunn2010-09-091-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Hi everyone, This simple patch fixes a problem I noticed on the xscale where incorrect values are sometimes reported by the reg command. The problem can occur when requesting the value of registers in the xscale-specific register cache. With a couple of exceptions, none of the registers in the xscale register cache are automatically retrieved on debug entry. This is probably fine, as they are unlikely to be needed on a regular basis during a typical debug session, and they can be retrieved when explicitly requested by name using the reg command. The problem is that once this is done, the register remains marked as valid for the remainder of the OpenOCD session, and the reg command will henceforth always report the same value because it is obtained from the cache and is never again retrieved from the debug handler on the target. The fix is to mark all registers in the xscale register cache as invalid on debug entry (before the two exceptions are retrieved), thus forcing retrieval (when requested) from the target across resumptions in execution, and avoiding the reporting of stale values. Small addition change by Øyvind: change 'i' to unsigned to fix compiler warning for xscale_debug_entry() fn.
