2015-04-02py: Add finer configuration of static funcs when not in stackless mode.Damien George
Also rename call_args_t to mp_call_args_t.
2015-04-03vm: If there's no heap to call function in stackless manner, call via C stack.Paul Sokolovsky
2015-04-03vm: Initial support for calling bytecode functions w/o C stack ("stackless").Paul Sokolovsky
2015-03-20py: Allow retrieving a function's __name__.stijn
Disabled by default. Enabled on unix and stmhal ports.
2015-02-15py: Make old_globals part of mp_code_state structure.Paul Sokolovsky
Conceptually it is part of code state, so let it be allocated in the same way as the rest of state.
2015-02-13py: Implement sdiv/udiv for inline Thumb assembler.Damien George
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George
See issue #699.
2015-01-14py: Add "default" to switches to allow better code flow analysis.Damien George
This helps compiler produce smaller code. Saves 124 bytes on stmhal and bare-arm.
2015-01-12py: Allow to compile with -Wstrict-prototypes.Damien George
2015-01-11py: Remove unnecessary BINARY_OP_EQUAL code that just checks pointers.Damien George
Previous patch c38dc3ccc76d1a9bf867704f43ea5d15da3fea7b allowed any object to be compared with any other, using pointer comparison for a fallback. As such, existing code which checked for this case is no longer needed.
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-11-05py: Fix some macros defines; cleanup some includes.Damien George
2014-10-25py: Store bytecode arg names in bytecode (were in own array).Damien George
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.
2014-10-03py: Change [u]int to mp_[u]int_t in qstr.[ch], and some other places.Damien George
This should pretty much resolve issue #50.
2014-09-29py: Fix types, uint -> mp_uint_t.Damien George
2014-09-23stmhal: Initialise stack pointer correctly.Damien George
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).
2014-09-04py: Use variable length encoded uints in more places in bytecode.Damien George
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.
2014-08-30Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George
Addressing issue #50, still some way to go yet.
2014-08-24py: Fix bug where GC collected native/viper/asm function data.Damien George
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.
2014-08-15py: Viper can now store to global.Damien George
2014-08-15py: Allow viper to have type annotations.Damien George
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
2014-07-03Rename machine_(u)int_t to mp_(u)int_t.Damien George
See discussion in issue #50.
2014-07-01stackctrl: Add "mp_" prefix.Paul Sokolovsky
2014-06-27py: Add portable framework to query/check C stack usage.Paul Sokolovsky
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.
2014-06-11objfun: Remove no longer used mp_obj_fun_prepare_simple_args().Paul Sokolovsky
2014-06-11objfun: Factor out mp_setup_code_state() function to set up code_state object.Paul Sokolovsky
It needs to be reused for generator functions, too.
2014-06-08Merge branch 'alloca' of github.com:marcusva/micropython into marcusva-allocaDamien George
2014-06-08py: Simplify function call of a bytecode object.Damien George
2014-06-07py: Implement default keyword only args.Damien George
Should finish addressing issue #524.
2014-06-07py: Merge mp_execute_bytecode into fun_bc_call.Damien George
This reduces stack usage by 16 words (64 bytes) for stmhal/ port. See issue #640.
2014-06-07- FreeBSD provides alloca() via stdlib.h, in contrast to Linux and WindowsMarcus von Appen
- Move the includes for alloca() intp mpconfigport.h
2014-06-01Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George
This renames: MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT See issue #35 for discussion.
2014-05-31objfun: Typo fixes in comments.Paul Sokolovsky
2014-05-21py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George
See issue #608 for justification.
2014-05-17py: More const usage.Paul Sokolovsky
2014-05-13py, unix: Add copyright for modules I worked closely on.Paul Sokolovsky
2014-05-10py: Tidy up returning NULL which should be MP_OBJ_NOT_SUPPORTED.Damien George
2014-05-10py: Combine native emitters to 1 glue function; distinguish viper.Damien George
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.
2014-05-10py: Rename byte_code to bytecode everywhere.Damien George
bytecode is the more widely used. See issue #590.
2014-05-03Add license header to (almost) all files.Damien George
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/.
2014-05-03Merge pull request #552 from stinos/mingw-allocaPaul Sokolovsky
py: Use <alloca.h> for alloca()
2014-05-03objclosure, objcell: Print detailed representation if was requested.Paul Sokolovsky
Well, it is bound to "detailed error reporting", but that's closest what we have now without creating new entities.
2014-05-03py: Use <alloca.h> for alloca()stijn
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.
2014-05-02py, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky
Specifically, nlr.h does.
2014-05-01objfun: More debug logging.Paul Sokolovsky
2014-05-01objgenerator: Fix check for too few args passed to gen function.Paul Sokolovsky
