Damien George 7860c2a68a py: Fix some macros defines; cleanup some includes. 2014-11-05 21:16:41 +00:00
Damien George 1084b0f9c2 py: Store bytecode arg names in bytecode (were in own array).
This saves a lot of RAM for 2 reasons:

1. For functions that don't have default values, var args or var kw
args (which is a large number of functions in the general case), the
mp_obj_fun_bc_t type now fits in 1 GC block (previously needed 2 because
of the extra pointer to point to the arg_names array).  So this saves 16
bytes per function (32 bytes on 64-bit machines).

2. Combining separate memory regions generally saves RAM because the
unused bytes at the end of the GC block are saved for 1 of the blocks
(since that block doesn't exist on its own anymore).  So generally this
saves 8 bytes per function.

Tested by importing lots of modules:

- 64-bit Linux gave about an 8% RAM saving for 86k of used RAM.
- pyboard gave about a 6% RAM saving for 31k of used RAM.

Damien George 39dc145478 py: Change [u]int to mp_[u]int_t in qstr.[ch], and some other places.
This should pretty much resolve issue #50.

Damien George a7329615eb py: Fix types, uint -> mp_uint_t. 2014-09-29 19:42:06 +01:00
Damien George eaaebf3291 stmhal: Initialise stack pointer correctly.
Stack is full descending and must be 8-byte aligned.  It must start off
pointing to just above the last byte of RAM.

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

Addresses issue #872 (among many other undiscovered issues).

Damien George b534e1b9f1 py: Use variable length encoded uints in more places in bytecode.
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.

Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

Damien George e6c0dff967 py: Viper can now store to global. 2014-08-15 23:47:59 +01:00
Damien George 2ac4af6946 py: Allow viper to have type annotations.
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

Paul Sokolovsky caa7334141 stackctrl: Add "mp_" prefix. 2014-07-01 02:14:08 +03:00
Paul Sokolovsky 23668698cb py: Add portable framework to query/check C stack usage.
Such mechanism is important to get stable Python functioning, because Python
function calling is handled with C stack. The idea is to sprinkle
STACK_CHECK() calls in places where there can be C recursion.

TODO: Add more STACK_CHECK()'s.

Damien George ccc85ea0da py: Combine native emitters to 1 glue function; distinguish viper.
This patch simplifies the glue between native emitter and runtime,
and handles viper code like inline assember: return values are
converted to Python objects.

Fixes issue #531.

Damien George 3417bc2f25 py: Rename byte_code to bytecode everywhere.
bytecode is the more widely used.  See issue #590.

Damien George 04b9147e15 Add license header to (almost) all files.
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/.

Paul Sokolovsky 7a14022604 Merge pull request #552 from stinos/mingw-alloca

Paul Sokolovsky 418aca976c objclosure, objcell: Print detailed representation if was requested.
Well, it is bound to "detailed error reporting", but that's closest what we
have now without creating new entities.

stijn 98e2ee0ec1 py: Use <alloca.h> for alloca()
alloca() is declared in alloca.h which als happens to be included by stdlib.h.
On mingw however it resides in malloc.h only.
So if we include alloca.h directly, and add an alloca.h for mingw in it's port
directory we can get rid of the mingw-specific define to include malloc.h
and the other ports are happy as well.

Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.

Damien George 2827d62e8b py: Implement keyword-only args.
Implements 'def f(*, a)' and 'def f(*a, b)', but not default
keyword-only args, eg 'def f(*, a=1)'.

Partially addresses issue #524.

Paul Sokolovsky 353b0289f3 py: Add win32-specific header for alloca(). 2014-04-20 22:24:44 +03:00
Damien George a3f94e0030 py: Add arg checking helper functions.
These are to assist in writing native C functions that take positional
and keyword arguments.  mp_arg_check_num is for just checking the
number of arguments is correct.  mp_arg_parse_all is for parsing
positional and keyword arguments with default values.

Damien George b11b85adaa py: Allow to pass buffer protocol flags to get_buffer helper funcs. 2014-04-18 22:59:24 +01:00
Damien George 57a4b4f178 py: Add typecode to buffer protocol.
When querying an object that supports the buffer protocol, that object
must now return a typecode (as per binary.[ch]).  This does not have to
be honoured by the caller, but can be useful for determining element
size.

Damien George 3fd2d7fad2 py: Tidy up function argument error messages.

Damien George de7c425139 py: Simplify objfun/objgenerator connection, no need to call bc_get. 2014-04-17 19:16:11 +01:00
Paul Sokolovsky f26a30710c objfun: Add local header.
This follows pattern already used for objtuple, etc.: objfun.h's content
is not public - each and every piece of code should not have access to it.
It's not private either - with out architecture and implementation language
(C) it doesn't make sense to keep implementation of each object strictly
private and maintain cumbersome accessors. It's "local" - intended to be
used by a small set of "friend" (in C++ terms) objects.

Damien George 8a1cab952f py: Fix mp_get_buffer, and use it in more places.
Must use mp_obj_get_type to get the type of an object.  Can't assume
mp_obj_t is castable to mp_obj_base_t.

Damien George 8721087661 py: Big improvements to inline assembler.
Improved the Thumb assembler back end.  Added many more Thumb
instructions to the inline assembler.  Improved parsing of assembler
instructions and arguments.  Assembler functions can now be passed the
address of any object that supports the buffer protocol (to get the
address of the buffer).  Added an example of how to sum numbers from
an array in assembler.
