* py: For malloc and vstr functions, use size_t exclusively for int type.Damien George2014-09-25
| | | | | | It seems most sensible to use size_t for measuring "number of bytes" in malloc and vstr functions (since that's what size_t is for). We don't use mp_uint_t because malloc and vstr are not Micro Python specific.

* | py: Free non-interned strings in the parser when not needed.Damien George2014-09-23
| | | | | | | | | | | | | | | | | | | | | | mp_parse_node_free now frees the memory associated with non-interned strings. And the parser calls mp_parse_node_free when discarding a non-used node (such as a doc string). Also, the compiler now frees the parse tree explicitly just before it exits (as opposed to relying on the caller to do this). Addresses issue #708 as best we can.

* / | stmhal: Initialise stack pointer correctly.Damien George2014-09-23
|/ / | | | | | | | | | | | | | | | | | | | | | | | | Stack is full descending and must be 8-byte aligned. It must start off pointing to just above the last byte of RAM. Previously, stack started pointed to last byte of RAM (eg 0x2001ffff) and so was not 8-byte aligned. This caused a bug in combination with alloca. This patch also updates some debug printing code. Addresses issue #872 (among many other undiscovered issues).

| * stmhal: Add pulse_width_ratio to timer channel object.Damien George2014-09-21
| | | | | | | | | | | | | | This allows to set the pulse width (for PWM mode) as a ratio relative to the period of the timer. Eg, 0.5 is a 50% duty cycle. You can set the ratio in the channel init, or using channel.pulse_width_ratio; the latter can also read the pulse width as a ratio.

* py: Make dict use a bit less RAM when iterating; properly del values.Damien George2014-09-17
| | | | | | | | Heap RAM was being allocated to print dicts and do some other types of iterating. Now these iterations use 1 word of state on the stack. Deleting elements from a dict was not allowing the value to be reclaimed by the GC. This is now fixed.
* stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.Damien George2014-09-15
| | | | | | | | | By measuring SD card addresses in blocks and not bytes, one can get away with using 32-bit numbers. This patch also uses proper atomic lock/unlock around SD card read/write, adds SD.info() function, and gives error code for failed read/writes.

| | | | | | | | sys.exit always raises SystemExit so doesn't need a special implementation for each port. If C exit() is really needed, use the standard os._exit function. Also initialise mp_sys_path and mp_sys_argv in teensy port.

* | py: Load strings as objects when compiling viper.Damien George2014-09-12
| | | | | | | | | | | | | | | | | | Eventually, viper wants to be able to use raw pointers to strings and arrays for efficient access. But for now, let's just load strings as a Python object so they can be used as normal. This will anyway be compatible with eventual intended viper behaviour. Addresses issue #857.
