I do not know what is the reasonable number of buckets. If there are enough buckets, the result will be accurate. I propose increase the maximum number of buckets to 128K. If the size of program text section is less than 256KB, every two bytes will be occupied by one buckets. (The minimum size of one buckets is 2 bytes in gprof implementation.)

2013-09-13gdb_server: Do not set gdb_con->sync to true for new connectionsAnton Kolesov
In GDB connected to OpenOCD there is a command "monitor gdb_sync" which makes next stepi command to be ignored while GDB still will get an updated target state. This command sets gdb_connection->sync field to true to notify that stepi should be ignored. This field is set to true for all new connection and is set to false after first "continue" command. However if first resume command is stepi/nexti then it will be ignored and result will confuse GDB client, it will report that target received signal SIGINT. This patch sets this field to false for new connections, thus stepi/nexti will work properly when it is a first resume command.

These versions are easy to extend to generate 8-byte accesses to support 64-bit targets, although it requires some conformity from all target implementations (i.e. they need to refuse unsupported access sizes with some defined error code, so we can try again with a smaller one).

2013-09-08mini51: support for Nuvoton NuMicro Mini51 series flash memoryCosmin Gorgovan
Adds a flash driver for Nuvoton MINI51, MINI52 and MINI54 microcontrollers. At the moment, it only supports the erase and write operations. These microcontrollers have a 4 / 8 / 16 KB APROM for application code and a 2 KB LDROM for bootloaders. When the MCU has booted off the APROM, the LDROM isn't mapped in memory but can be programmed, and the other way around. This means that the ARM core is typically rebooted for programming. After a successful write or erase operation, it is rebooted again, using the initial boot source. This driver only supports programming the APROM. This driver is a pure JTAG implementation, it doesn't use any SRAM. I've tested it on a MINI54ZAN microcontroller using an ST-LINK/V2. With the microcontroller running at the default clock frequency of 22.1184 MHz, speed seems to be around 1.1 KB/s.

This adds example config and flash driver for russian Cortex-M3 microcontroller model. Run-time tested on MDR32F9Q2I evaluation board; the flash driver should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware to test. There're no status bits at all, the datasheets specifies some delays for flash operations instead. All being in <100us range, they're hard to violate with JTAG, I hope. There're also no flash identification registers so the flash size and type has to be hardcoded into the config. The flashing is considerably complicated because the flash is split into pages, and each page consists of 4 interleaved non-consecutive "sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the fastest way is to latch the page and sector address and then write only the part that should go into the current page and current sector. Performance testing results with adapter_khz 1000 and the chip running on its default HSI 8MHz oscillator: When working area is specified, a target helper algorithm is used: wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s) This can theoretically be sped up by ~1.4 times if the helper algorithm is fed some kind of "loader instructions stream" to allow sector-by-sector writing. Pure JTAG implementation (when target memory area is not available) flashes all the 128k memory in 49.5s. Flashing "info" memory region is also implemented, but due to the overlapping memory addresses (resulting in incorrect memory map calculations for GDB) it can't be used at the same time, so OpenOCD needs to be started this way: -c "set IMEMORY true" -f target/mdr32f9q2i.cfg It also can't be read/verified because it's not memory-mapped anywhere ever, and OpenOCD NOR framework doesn't really allow to provide a custom handler that would be used when verifying.

2013-08-07stlink: add SWO tracing supportAndrey Yurovsky
Enable reading the SWO trace output via STLinkv2 dongles that support it. This adds an optional initialization parameter "trace" with which the user specifies a destination file where SWO trace output is appended as it comes in as well as the trace module's source clock rate. STLink will be configured for a 2MHz SWO data rate (STLink's highest supported rate) if the source clock is > 2MHz, otherwise the source clock is used as the data rate directly. For example: trace swo.log 168000000 If "trace" is specified with a usable file path, the stlink_usb driver will attempt to configure and read SWO trace data as follows: - on _run(), the target's TPI and TMI are configured and the STLinkv2 is told to enable tracing. Only generic ARM TPI and TMI registers are configured, any MCU-specific settings (ex: pin routing) are the responsibility of the target firmware. The configuration applied is based on the STLinkv2's capabilities (UART emulation). - on _v2_get_status(), the trace data (if any) is fetched from the STLink after the target status is checked and the target is found to be running. - on _halt(), the STLink is told to disable tracing. When fetching trace data, the entire trace frame is written to the output file and that data is flushed. An external tool may be used to parse the trace data into a more human-readable format. Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).

2013-08-07gdb_server: check target before executing event callbackHsiangkai Wang
As debugging multi-targets, every target has its own gdb connection. If there are two connections, gdb_target_callback_event_handler will be registered twice. Everytime event occurs, the registered callback will be executed twice. If both targets are running, as user issues ctrl-c in one gdb client, both connections will send "stop reply" to GDB clients even TARGET_EVENT_GDB_HALT is caused by one of them. The commit fix above problem as debugging multi-targets.

2013-08-07gdb_server: add target_debug_reason for program exit detectionHsiangkai Wang
Currently, there is no way to notify gdb that program has exited. Add new target_debug_reason called DBG_REASON_EXIT to notify gdb the condition has occured. If the debug reason is DBG_REASON_EXIT, gdb_server will send 'W' packet to tell gdb the process has exited.
