Damien George 968bf34c4c py: Remove unnecessary LOAD_CONST_ID bytecode.
It's the same as LOAD_CONST_STR.

Damien George 5f6a25fc50 py: Wrap #if's around emitter functions that are used only by emitcpy.
3 emitter functions are needed only for emitcpy, and so we can #if them
out when compiling with emitcpy support.

Also remove unused SETUP_LOOP bytecode.

Damien George 3558f62fb5 py: Making closures now passes pointer to stack, not a tuple for vars.
Closed over variables are now passed on the stack, instead of creating a
tuple and passing that.  This way memory for the closed over variables
can be allocated within the closure object itself.  See issue #510 for
background.

Damien George 729f7b42d6 py: Merge BINARY_OP_SUBSCR and store_subscr (w/ delete) into subscr.
mp_obj_t->subscr now does load/store/delete.

Damien George df8127a17e py: Remove unique_codes from emitglue.c. Replace with pointers.
Attempt to address issue #386.  unique_code_id's have been removed and
replaced with a pointer to the "raw code" information.  This pointer is
stored in the actual byte code (aligned, so the GC can trace it), so
that raw code (ie byte code, native code and inline assembler) is kept
only for as long as it is needed.  In memory it's now like a tree: the
outer module's byte code points directly to its children's raw code.  So
when the outer code gets freed, if there are no remaining functions that
need the raw code, then the children's code gets freed as well.

This is pretty much like CPython does it, except that CPython stores
indexes in the byte code rather than machine pointers.  These indices
index the per-function constant table in order to find the relevant
code.

Damien George d66ae18640 py: Simplify stack get/set to become stack adjust in emitters.
Can do this now that the stack size calculation is improved.

Damien George 069a35e3a5 py, compiler: Improve stack depth counting.
Much less of a hack now.  Hopefully it's correct!

Damien George 6f355fd3b9 py: Make labels unsigned ints (converted from int).
Labels should never be negative, and this modified type signature
reflects that.

Damien George 922ddd6415 py, compile: Combine have_star_arg, have_dbl_star_arg into star_flags.
Small reduction in ROM, heap and stack usage.

Damien George 882b363564 py: Move to Python 3.4.0 compatibility.
Very little has changed.  In Python 3.4 they removed the opcode
STORE_LOCALS, but in Micro Python we only ever used this for CPython
compatibility, so it was a trivial thing to remove.  It also allowed to
clean up some dead code (eg the 0xdeadbeef in class construction), and
now class builders use 1 less stack word.

Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not
yet understood.  Still, all tests (apart from bytecode test) still pass.
Bytecode tests needs some more attention, but they are not that
important anymore.

Damien George 3056509e00 py: Rename and reorder parameters in emit_make_function/closure.
In preparation for implementing default keyword arguments.

Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

Damien George 9aa2a527b5 py: Tidy up BINARY_OPs; negation done by special NOT bytecode.
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new
special NOT bytecode.

Damien George e24b563796 py: Fix emitcpy so continue is compatible with CPython. 2014-02-01 21:56:25 +00:00
Damien George 08d075592f py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int.
LOAD_METHOD bug was: emitbc did not correctly calculate the amount of
stack usage for a LOAD_METHOD operation.

small int bug was: int was being used to pass small ints, when it should
have been machine_int_t.

Damien George 41d02b654e py: Improve freeing of emitters in mp_compile.

and native).

qstrdefsport.h

Damien George 08335004cf Add source file name and line number to error messages.
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Damien George e67ed5d285 Improve configurability for native x64/thumb emitter.
With MICROPY_EMIT_X64 and MICROPY_EMIT_THUMB disabled, the respective
emitters and assemblers will not be included in the code.  This can
significantly reduce binary size for unix version.

Damien de690d128b Add unix-cpy, used to test Micro Python byte code against CPython. 2013-12-29 18:01:01 +00:00
Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
