Towards resolving issue #50.
py: Use variable length encoded uints in more places in bytecode.2014-09-04T13:44:01+00:00Damien Georgedamien.p.george@gmail.com2014-09-04T13:44:01+00:00urn:sha1:b534e1b9f14c189d2cef209d40f598e62164694a
Code-info size, block name, source name, n_state and n_exc_stack now use
variable length encoded uints. This saves 7-9 bytes per bytecode
function for most functions.
py: Allow viper to have type annotations.2014-08-15T15:45:41+00:00Damien Georgedamien.p.george@gmail.com2014-08-15T15:45:41+00:00urn:sha1:2ac4af6946543ae96cf3659468e1b8cabb057f85
Viper functions can now be annotated with the type of their arguments
and return value. Eg:
@micropython.viper
def f(x:int) -> int:
return x + 1
py: Improve encoding scheme for line-number to bytecode map.2014-07-31T16:12:01+00:00Damien Georgedamien.p.george@gmail.com2014-07-31T16:12:01+00:00urn:sha1:4747becc6423e8161519ad6850e09137f14742a8
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.
emitbc: Fix structure field alignment issue.2014-07-12T12:57:28+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-07-12T11:51:48+00:00urn:sha1:58c9586c343870e721512975af55cf210b45f756
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).
Rename machine_(u)int_t to mp_(u)int_t.2014-07-03T12:25:24+00:00Damien Georgedamien.p.george@gmail.com2014-07-03T12:25:24+00:00urn:sha1:40f3c026823f8951a2fa04e9c7fc93c75bc27bec
See discussion in issue #50.
py: Improvements to native emitter.2014-06-30T04:17:25+00:00Damien Georgedamien.p.george@gmail.com2014-06-30T04:17:25+00:00urn:sha1:b601d9574ad03a18d3eb476d631f547c7ea28243
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.
py: Include mpconfig.h before all other includes.2014-06-21T19:43:22+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-06-21T19:43:22+00:00urn:sha1:59c675a64c1d9757d50ad4627da67a6f996a99fb
It defines types used by all other headers.
Fixes #691.
py: For optimization level -O3 and higher, remove lineno info from bytecode.2014-06-03T09:32:59+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-06-02T16:39:15+00:00urn:sha1:b8f117dd32aae6d2d8108ba101961d00df123e4fpy: Fix break from within a for loop.2014-05-30T14:20:41+00:00Damien Georgedamien.p.george@gmail.com2014-05-30T14:20:41+00:00urn:sha1:25c84643b6c4da169cdb11de54f027e3c477c301
Needed to pop the iterator object when breaking out of a for loop. Need
also to be careful to unwind exception handler before popping iterator.
Addresses issue #635.
