* py: Fix bug in mpn_shl (multi-prec int shift left).Damien George2014-08-07
| | | | | Before this patch, eg, 1 << 75 (or any large multiple of 15) was setting the MSB in the digits, which is outside the valid range of DIG_MASK.
* Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.Damien George2014-08-04
| | | | | | | qstr_init is always called exactly before mp_init, so makes sense to just have mp_init call it. Similarly with mp_init_emergency_exception_buf. Doing this makes the ports simpler and less error prone (ie they can no longer forget to call these).
* py: Improve encoding scheme for line-number to bytecode map.Damien George2014-07-31
| | | | | | | | | | | | | | | | | | | | Reduces by about a factor of 10 on average the amount of RAM needed to store the line-number to bytecode map in the bytecode prelude. Using CPython3.4's stdlib for statistics: previously, an average of 13 bytes were used per (bytecode offset, line-number offset) pair, and now with this improvement, that's down to 1.3 bytes on average. Large RAM usage before was due to some very large steps in line numbers, both from the start of the first line in a function way down in the file, and also functions that have big comments and/or big strings in them (both cases were significant). Although the savings are large on average for the CPython stdlib, it won't have such a big effect for small scripts used in embedded programming. Addresses issue #648.

| * py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.Damien George2014-07-31
| | | | | | | | Addresses issue #724.
| * py: Add mp_obj_str_builder_end_with_len.Damien George2014-07-31
| | | | | | | | | | This allows to create str's with a smaller length than initially asked for.
* | py: Improve handling of long-int overflow.Damien George2014-07-31
|/ | | | | | | | | | This removes mpz_as_int, since that was a terrible function (it implemented saturating conversion). Use mpz_as_int_checked and mpz_as_uint_checked. These now work correctly (they previously had wrong overflow checking, eg print(chr(10000000000000)) on 32-bit machine would incorrectly convert this large number to a small int).
* py: Change lexer stream API to return bytes not chars.Damien George2014-07-30
| | | | Lexer is now 8-bit clean inside strings.

| * Add support for storing args during an exception raised by an irq.Dave Hylands2014-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The user code should call micropython.alloc_emergency_exception_buf(size) where size is the size of the buffer used to print the argument passed to the exception. With the test code from #732, and a call to micropython.alloc_emergenncy_exception_buf(100) the following error is now printed: ```python >>> import heartbeat_irq Uncaught exception in Timer(4) interrupt handler Traceback (most recent call last): File "0://heartbeat_irq.py", line 14, in heartbeat_cb NameError: name 'led' is not defined ```

* | py: Make id() return small int for the most common address space mapping.Paul Sokolovsky2014-07-28
| | | | | | | | | | | | | | | | | | | | | | Many OSes/CPUs have affinity to put "user" data into lower half of address space. Take advantage of that and remap such addresses into full small int range (including negative part). If address is from upper half, long int will be used. Previously, small int was returned for lower quarter of address space, and upper quarter. For 2 middle quarters, long int was used, which is clearly worse schedule than the above.

* py: Make print() accept "file" argument, and actually print to stream.Paul Sokolovsky2014-07-19
| | | | | And not system printf(), like it was before. For this, move pfenv_printf() from stmhal port to py/.
* py: Add stream reading of n unicode chars; unicode support by default.Damien George2014-07-19
| | | | | | | | | | | | | With unicode enabled, this patch allows reading a fixed number of characters from text-mode streams; eg file.read(5) will read 5 unicode chars, which can made of more than 5 bytes. For an ASCII stream (ie no chars > 127) it only needs to do 1 read. If there are lots of non-ASCII chars in a stream, then it needs multiple reads of the underlying object. Adds a new test for this case. Enables unicode support by default on unix and stmhal ports.

* emitbc: Fix structure field alignment issue.Paul Sokolovsky2014-07-12
| | | | | | | dummy_data field is accessed as uint value (e.g. in emit_write_bytecode_byte_ptr), but is not aligned as such, which causes bus errors or incorrect behavior on any arch requiring strictly aligned data (ARM pre-v7, MIPS, etc, etc).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Native emitter can now compile try/except blocks using nlr_push/nlr_pop. It probably only works for 1 level of exception handling. It doesn't work on Thumb (only x64). Native emitter can also handle some additional op codes. With this patch, 198 tests now pass using "-X emit=native" option to micropython.
