* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py: Allow to properly disable builtin slice operation.Damien George2014-12-27
| | | | | | | This patch makes the MICROPY_PY_BUILTINS_SLICE compile-time option fully disable the builtin slice operation (when set to 0). This includes removing the slice sytanx from the grammar. Now, enabling slice costs 4228 bytes on unix x64, and 1816 bytes on stmhal.
* py: Allow to properly disable builtin "set" object.Damien George2014-12-27
| | | | | | | | This patch makes MICROPY_PY_BUILTINS_SET compile-time option fully disable the builtin set object (when set to 0). This includes removing set constructor/comprehension from the grammar, the compiler and the emitters. Now, enabling set costs 8168 bytes on unix x64, and 3576 bytes on stmhal.
* py: Remove last uses of printf from compile; use proper SyntaxError.Damien George2014-12-21
|
* py: Move global/nonlocal decl code to compiler for proper SyntaxError.Damien George2014-12-21
| | | | | | This patch gives proper SyntaxError exceptions for bad global/nonlocal declarations. It also reduces code size: 304 bytes on unix x64, 132 bytes on stmhal.
* py: Remove unnecessary RULE_none and PN_none from parser.Damien George2014-12-20
|
* py: Fix optimised for-loop compiler so it follows proper semantics.Damien George2014-12-12
| | | | | | | | | You can now assign to the range end variable and the for-loop still works correctly. This fully addresses issue #565. Also fixed a bug with the stack not being fully popped when breaking out of an optimised for-loop (and it's actually impossible to write a test for this case!).
* py: Fix a semantic issue with range optimisation.Damien George2014-12-11
| | | | | | | Now you can assign to the range variable within the for loop and it will still work. Partially addresses issue #565.
* py: Make functions static where appropriate.Damien George2014-12-10
|
* py: Fix bug with right-shifting small ints by large amounts.Paul Sokolovsky2014-11-02
| | | | Undefined behavior in C, needs explicit check.
* py: Add more compiler optimisations for constant if/while conditions.Damien George2014-10-17
|
* py: Simplify compilation of elif blocks.Damien George2014-10-17
|
* py: Fix compiling of nested while/for and exception handler.Damien George2014-10-17
| | | | Addresses issue #912.
* py: Make compiler return a proper exception on SyntaxError.Damien George2014-10-05
|
* py: Fix unix-cpy to compile with uint->mp_uint_t changes.Damien George2014-10-03
|
* py: Change [u]int to mp_[u]int_t in qstr.[ch], and some other places.Damien George2014-10-03
| | | | This should pretty much resolve issue #50.
* py: Convert [u]int to mp_[u]int_t where appropriate.Damien George2014-10-03
| | | | Addressing issue #50.
* py: Free non-interned strings in the parser when not needed.Damien George2014-09-23
| | | | | | | | | | | 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: Convert [u]int to mp_[u]int_t in emit.h and associated .c files.Damien George2014-09-08
| | | | Towards resolving issue #50.
* py: Add support for emitting native x86 machine code.Damien George2014-09-06
|
* Code style/whitespace cleanup; remove obsolete headers.Damien George2014-09-03
| | | | And move the MAP_ANON redefinition from py/asmx64.c to unix/alloc.c.
* py: Add compiler optimisation for conditions in parenthesis.Damien George2014-08-29
| | | | | | | Optimises: if () -> if False if (x,...) -> if True if (a and b) -> if a and b
* Basic native ARM emitterFabian Vogt2014-08-27
|
* py: Fix typing of viper locals; allow default types in annotation.Damien George2014-08-15
|
* py: Allow viper to have type annotations.Damien George2014-08-15
| | | | | | | | | 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
* py: Clean up and simplify functions in scope; add STATIC in compiler.Damien George2014-08-15
| | | | | Some small code clean-ups that result in about 80 bytes ROM saving for stmhal.
* moductypes: Foreign data interface module, roughly based on ctype ideas.Paul Sokolovsky2014-07-09
| | | | | But much smaller and memory-efficient. Uses Python builtin data structures (dict, tuple, int) to describe structure layout.
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* py: Improvements to native emitter.Damien George2014-06-30
| | | | | | | | | | | Native emitter can now compile try/except blocks using nlr_push/nlr_pop. It probably only works for 1 level of exception handling. It doesn't work on Thumb (only x64). Native emitter can also handle some additional op codes. With this patch, 198 tests now pass using "-X emit=native" option to micropython.
* py: Include mpconfig.h before all other includes.Paul Sokolovsky2014-06-21
| | | | | | It defines types used by all other headers. Fixes #691.
* Prefix ARRAY_SIZE with micropython prefix MP_Emmanuel Blot2014-06-19
|
* py: Implement default keyword only args.Damien George2014-06-07
| | | | Should finish addressing issue #524.
* py: Fix stack underflow with optimised for loop.Damien George2014-05-31
|
* py: Fix break from within a for loop.Damien George2014-05-30
| | | | | | | Needed to pop the iterator object when breaking out of a for loop. Need also to be careful to unwind exception handler before popping iterator. Addresses issue #635.
* py: Fix check of small-int overflow when parsing ints.Damien George2014-05-28
| | | | Also unifies use of SMALL_INT_FITS macro across parser and runtime.
* py: Don't automatically intern strings in parser.Damien George2014-05-25
| | | | | | | | This completes non-automatic interning of strings in the parser, so that doc strings don't take up RAM. It complicates the parser and compiler, and bloats stmhal by about 300 bytes. It's complicated because now there are 2 kinds of parse-nodes that can be strings: interned leaves and non-interned structs.
* Tidy up some configuration options.Damien George2014-05-21
| | | | | | | | | | MP_ALLOC_* -> MICROPY_ALLOC_* MICROPY_PATH_MAX -> MICROPY_ALLOC_PATH_MAX MICROPY_ENABLE_REPL_HELPERS -> MICROPY_HELPER_REPL MICROPY_ENABLE_LEXER_UNIX -> MICROPY_HELPER_LEXER_UNIX MICROPY_EXTRA_* -> MICROPY_PORT_* See issue #35.
* py: Rename BYTE_CODE to BYTECODE (this was missed in previous rename).Damien George2014-05-12
|
* py: Rename byte_code to bytecode everywhere.Damien George2014-05-10
| | | | bytecode is the more widely used. See issue #590.
* py, compiler: Add basic support for A=const(123).Damien George2014-05-08
| | | | | | | | | | | You can now do: X = const(123) Y = const(456 + X) and the compiler will replace X and Y with their values. See discussion in issue #266 and issue #573.
* py, compiler: Improve passes; add an extra pass for native emitter.Damien George2014-05-07
|
* py, compiler: Start adding support for compile-time constants.Damien George2014-05-07
| | | | Just a start, no working code yet. As per issue #573.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | 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: Add '*' qstr for 'import *'; use blank qstr for comprehension arg.Damien George2014-04-27
|
* py: Remove unnecessary LOAD_CONST_ID bytecode.Damien George2014-04-27
| | | | It's the same as LOAD_CONST_STR.
* py: Save some ROM by shortening compiler error messages.Damien George2014-04-27
| | | | Messages are still explanatory, while taking a little less ROM.
* py: Change the way function arguments are compiled.Damien George2014-04-27
| | | | | | | | New way uses slightly less ROM and RAM, should be slightly faster, and, most importantly, allows to catch the error "non-keyword arg following keyword arg". Addresses issue #466.
* py: Implement keyword-only args.Damien George2014-04-27
| | | | | | | Implements 'def f(*, a)' and 'def f(*a, b)', but not default keyword-only args, eg 'def f(*, a=1)'. Partially addresses issue #524.
* Add ARRAY_SIZE macro, and use it where possible.Damien George2014-04-26
|
* py: Add MICROPY_ENABLE_DOC_STRING, disabled by default.Damien George2014-04-25
| | | | | | Also add a few STATIC's to some compile functions that should have them. Addresses issue #521.
