Paul Sokolovsky e2d44e30c7 py: Add MICROPY_PY_BUILTINS_ENUMERATE, disable for minimal ports. 2015-04-06 23:51:29 +03:00
Damien George 56606f3475 py: Implement delete for property and descriptors.
Without this patch deleting a property, or class with descriptor, will
call the setter with a NULL value and lead to a crash.

Paul Sokolovsky acf6aec71c objstr: Avoid variable shadowing. 2015-04-04 01:24:59 +03:00
Paul Sokolovsky ac2f7a7f6a objstr: Add .splitlines() method.
splitlines() occurs ~179 times in CPython3 standard library, so was
deemed worthy to implement. The method has subtle semantic differences
from just .split("\n"). It is also defined as working for any end-of-line
combination, but this is currently not implemented - it works only with
LF line-endings (which should be OK for text strings on any platforms,
but not OK for bytes).

Damien George 51229afbde py: Increase fixed size of stack-info in native emitter.
This is a temporary fix.

Damien George 4112590a60 py, compiler: When just bytecode, make explicit calls instead of table.
When just the bytecode emitter is needed there is no need to have a
dynamic method table for the emitter back-end, and we can instead
directly call the mp_emit_bc_XXX functions.  This gives a significant
reduction in code size and a very slight performance boost for the
compiler.

This patch saves 1160 bytes code on Thumb2 and 972 bytes on x86, when
native emitters are disabled.

Overall savings in code over the last 3 commits are:

bare-arm: 1664 bytes.
minimal:  2136 bytes.
stmhal:    584 bytes (it has native emitter enabled).
cc3200:   1736 bytes.
2015-03-26 16:52:45 +00:00
Damien George a210c774f9 py, compiler: Remove emit_pass1 code, using emit_bc to do its job.
First pass for the compiler is computing the scope (eg if an identifier
is local or not) and originally had an entire table of methods dedicated
to this, most of which did nothing.  With changes from previous commit,
this set of methods can be removed and the methods from the bytecode
emitter used instead, with very little modification -- this is what is
done in this commit.

This factoring has little to no impact on the speed of the compiler
(tested by compiling 3763 Python scripts and timing it).

This factoring reduces code size by about 270-300 bytes on Thumb2 archs,
and 400 bytes on x86.
2015-03-26 16:52:45 +00:00
Damien George 542bd6b4a1 py, compiler: Refactor load/store/delete_id logic to reduce code size.

Paul Sokolovsky 0090c714ba objdict: Cast mp_obj_t to concrete types explicitly.

Damien George aedf583af2 py: Simplify some logic in compiler; add comments about CPython compat. 2015-03-25 22:06:47 +00:00
Paul Sokolovsky 3d598256df py: Cast mp_obj_t to concrete types explicitly.
mp_obj_t internal representation doesn't have to be a pointer to object,
it can be anything.

There's also a support for back-conversion in the form of MP_OBJ_UNCAST.
This is kind of optimization/status quo preserver to minimize patching the
existing code and avoid doing potentially expensive MP_OBJ_CAST over and
over. But then one may imagine implementations where MP_OBJ_UNCAST is very
expensive. But such implementations are unlikely interesting in practice.

Paul Sokolovsky 44cd46a7e4 objnamedtuple: Accept field list as a string.

Damien George 55b74d1ff5 py: Combine duplicated code that converts members from a lookup.
Despite initial guess, this code factoring does not hamper performance.
In fact it seems to improve speed by a little: running pystone(1.2) on
pyboard (which gives a very stable result) this patch takes pystones
from 1729.51 up to 1742.16.  Also, pystones on x64 increase by around
the same proportion (but it's much noisier).

Taking a look at the generated machine code, stack usage with this patch
is unchanged, and call is tail-optimised with all arguments in
registers.  Code size decreases by about 50 bytes on Thumb2 archs.

Paul Sokolovsky 07b8dc68d6 runtime: mp_load_method_maybe(): Don't use confusing "base" term.
"Base" should rather refer to "base type"."Base object for attribute
lookup" should rather be just "object".

Also, a case of common subexpression elimination.

Paul Sokolovsky 0ef01d0a75 py: Implement core of OrderedDict type.
Given that there's already support for "fixed table" maps, which are
essentially ordered maps, the implementation of OrderedDict just extends
"fixed table" maps by adding an "is ordered" flag and add/remove
operations, and reuses 95% of objdict code, just making methods tolerant
to both dict and OrderedDict.

Some things are missing so far, like CPython-compatible repr and comparison.

OrderedDict is Disabled by default; enabled on unix and stmhal ports.

Paul Sokolovsky cefcbb22b2 objarray: Implement array slice assignment.
This is rarely used feature which takes enough code to implement, so is
controlled by MICROPY_PY_ARRAY_SLICE_ASSIGN config setting, default off.
But otherwise it may be useful, as allows to update arbitrary-sized data
buffers in-place.

Slice is yet to implement, and actually, slice assignment implemented in
such a way that RHS of assignment should be array of the exact same item
typecode as LHS. CPython has it more relaxed, where RHS can be any sequence
of compatible types (e.g. it's possible to assign list of int's to a
bytearray slice).

Overall, when all "slice write" features are implemented, it may cost ~1KB
of code.

Damien George 4852e09c79 py: Fix adding of traceback so that it appends to existing info.

Most of printing infrastructure now uses streams, but mp_obj_print() used

mp_obj_print() to streams too, even though it may make sense to move it to
a separate file, as it is purely a debugging function now.

Relative imports are based of a package, so we're currently at a module

Damien George 7d414a1b52 py: Parse big-int/float/imag constants directly in parser.
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
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.

Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
This cleans up vstr so that it's a pure "variable buffer", and the user
can decide whether they need to add a terminating null byte.  In most
places where vstr is used, the vstr did not need to be null terminated
and so this patch saves code size, a tiny bit of RAM, and makes vstr
usage more efficient.  When null termination is needed it must be
done explicitly using vstr_null_terminate.

Damien George a5efcd4745 py: Specify unary/binary op name in TypeError error message.
Eg, "() + 1" now tells you that __add__ is not supported for tuple and

the table of names for slot lookup because it would be a waste of code
space to store the pretty name for each operator.
