This patch refactors some code so that it is easier to integrate new
inline assemblers for different architectures other than ARM Thumb.
py/compile: Add mp_compile_to_raw_code() to return raw code object.2015-11-20T12:30:37+00:00Damien Georgedamien.p.george@gmail.com2015-11-13T13:38:28+00:00urn:sha1:d4dba8823655c2715867f4d64e407de390c9d29e
This can then be passed to mp_raw_code_save_file to save a .mpy file.
py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.2015-10-01T23:11:11+00:00Damien Georgedamien.p.george@gmail.com2015-09-23T09:50:43+00:00urn:sha1:58e0f4ac50b3dc732cbfe0d7b04bb41951ac1329
With this patch parse nodes are allocated sequentially in chunks. This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.
Saves roughly 20% of RAM during parse stage.
py: Protect mp_parse and mp_compile with nlr push/pop block.2015-02-07T18:33:58+00:00Damien Georgedamien.p.george@gmail.com2015-02-07T18:33:58+00:00urn:sha1:0bfc7638baa4c5a4a2351364ab770a188dcab302
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.
This patch adds that feature in all places. This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.
py: Move to guarded includes for compile.h and related headers.2014-12-27T14:12:17+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-12-25T21:29:19+00:00urn:sha1:8ab6f9067412d9f73fe88d42d81c0b4c4f1fd20bpy: Implement proper context save/restore for eval/exec; factor code.2014-10-05T19:13:34+00:00Damien Georgedamien.p.george@gmail.com2014-10-05T19:13:34+00:00urn:sha1:c4d0868df1117ad243ee8f7238985a822b0f775d
This has benefits all round: code factoring for parse/compile/execute,
proper context save/restore for exec, allow to sepcify globals/locals
for eval, and reduced ROM usage by >100 bytes on stmhal and unix.
Also, the call to mp_parse_compile_execute is tail call optimised for
the import code, so it doesn't increase stack memory usage.
py: Free non-interned strings in the parser when not needed.2014-09-23T15:31:56+00:00Damien Georgedamien.p.george@gmail.com2014-09-23T15:31:56+00:00urn:sha1:52b5d76a6b0c5e4c779211fdf7bca56d87a2f83e
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.
py: Rename BYTE_CODE to BYTECODE (this was missed in previous rename).2014-05-12T21:35:37+00:00Damien Georgedamien.p.george@gmail.com2014-05-12T21:35:37+00:00urn:sha1:96f137b24a6c0b2e1e3c6f5fb8617b8a7f7896d6Add license header to (almost) all files.2014-05-03T22:27:38+00:00Damien Georgedamien.p.george@gmail.com2014-05-03T22:27:38+00:00urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
py, compiler: Clean up and compress scope/compile structures.2014-04-09T11:27:39+00:00Damien Georgedamien.p.george@gmail.com2014-04-09T11:27:39+00:00urn:sha1:78035b995ff7bd518cc1291aa70c966b53510fd9
Convert int types to uint where sensible, and then to uint8_t or
uint16_t where possible to reduce RAM usage.
