* all: Remove the "STATIC" macro and just use "static" instead.Angus Gratton2024-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The STATIC macro was introduced a very long time ago in commit d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

* py/obj: Convert make_new into a mp_obj_type_t slot.Jim Mussared2022-09-19
| | | | | | | | | | | Instead of being an explicit field, it's now a slot like all the other methods. This is a marginal code size improvement because most types have a make_new (100/138 on PYBV11), however it improves consistency in how types are declared, removing the special case for make_new.

* all: Make all mp_obj_type_t defs use MP_DEFINE_CONST_OBJ_TYPE.Jim Mussared2022-09-19

* py/obj: Make mp_obj_get_complex_maybe call mp_obj_get_float_maybe first.Damien George2022-07-25
| | | | | | | | | | | | | | | | | | This commit simplifies mp_obj_get_complex_maybe() by first calling mp_obj_get_float_maybe() to handle the cases corresponding to floats. Only if that fails does it attempt to extra a full complex number. This reduces code size and also means that mp_obj_get_complex_maybe() now supports user-defined classes defining __float__; in particular this allows user-defined classes to be used as arguments to cmath-module function. Furthermore, complex_make_new() can now be simplified to directly call mp_obj_get_complex(), instead of mp_obj_get_complex_maybe() followed by mp_obj_get_float(). This also improves error messages from complex with an invalid argument, it now raises "can't convert <type> to complex" rather than "can't convert <type> to float".

* all: Use mp_obj_malloc everywhere it's applicable.Jim Mussared2022-05-03
| | | | | | | | | | | | | | | This replaces occurences of foo_t *foo = m_new_obj(foo_t); foo->base.type = &foo_type; with foo_t *foo = mp_obj_malloc(foo_t, &foo_type); Excludes any places where base is a sub-field or when new0/memset is used. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
* py/objcomplex: Add mp_obj_get_complex_maybe for use in complex bin-op.Damien George2020-06-27
| | | | | | | | This allows complex binary operations to fail gracefully with unsupported operation rather than raising an exception, so that special methods work correctly. Signed-off-by: Damien George <damien@micropython.org>

* py: Expand type equality flags to 3 separate ones, fix bool/namedtuple.Damien George2020-02-11
| | | | | | | | | | | | | | | Both bool and namedtuple will check against other types for equality; int, float and complex for bool, and tuple for namedtuple. So to make them work after the recent commit 3aab54bf434e7f025a91ea05052f1bac439fad8c they would need MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST set. But that makes all bool and namedtuple equality checks less efficient because mp_obj_equal_not_equal() could no longer short-cut x==x, and would need to try __ne__. To improve this, this commit splits the MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST flags into 3 separate flags to give types more fine-grained control over how their equality behaves. These new flags are then used to fix bool and namedtuple equality. Fixes issue #5615 and #5620.
* py: Support non-boolean results for equality and inequality tests.Nicko van Someren2020-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements a more complete replication of CPython's behaviour for equality and inequality testing of objects. This addresses the issues discussed in #5382 and a few other inconsistencies. Improvements over the old code include: - Support for returning non-boolean results from comparisons (as used by numpy and others). - Support for non-reflexive equality tests. - Preferential use of __ne__ methods and MP_BINARY_OP_NOT_EQUAL binary operators for inequality tests, when available. - Fallback to op2 == op1 or op2 != op1 when op1 does not implement the (in)equality operators. The scheme here makes use of a new flag, MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST, in the flags word of mp_obj_type_t to indicate if various shortcuts can or cannot be used when performing equality and inequality tests. Currently four built-in classes have the flag set: float and complex are non-reflexive (since nan != nan) while bytearray and frozenszet instances can equal other builtin class instances (bytes and set respectively). The flag is also set for any new class defined by the user. This commit also includes a more comprehensive set of tests for the behaviour of (in)equality operators implemented in special methods.
* py: Downcase all MP_OBJ_IS_xxx macros to make a more consistent C API.Damien George2019-02-12
| | | | | | | | | | | | | | | | | | | | | These macros could in principle be (inline) functions so it makes sense to have them lower case, to match the other C API functions. The remaining macros that are upper case are: - MP_OBJ_TO_PTR, MP_OBJ_FROM_PTR - MP_OBJ_NEW_SMALL_INT, MP_OBJ_SMALL_INT_VALUE - MP_OBJ_NEW_QSTR, MP_OBJ_QSTR_VALUE - MP_OBJ_FUN_MAKE_SIG - MP_DECLARE_CONST_xxx - MP_DEFINE_CONST_xxx These must remain macros because they are used when defining const data (at least, MP_OBJ_NEW_SMALL_INT is so it makes sense to have MP_OBJ_SMALL_INT_VALUE also a macro). For those macros that have been made lower case, compatibility macros are provided for the old names so that users do not need to change their code immediately.
* py: Shorten error messages by using contractions and some rewording.Damien George2018-09-20
|
* all: Remove inclusion of internal py header files.Damien George2017-10-04
| | | | | | | | | | | | | | | | Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed.
* py/{objfloat,objcomplex}: Optimise MP_UNARY_OP_ABS by reusing variables.Damien George2017-09-18
|
* py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS.Paul Sokolovsky2017-09-18
| | | | | | | | | | This allows user classes to implement __abs__ special method, and saves code size (104 bytes for x86_64), even though during refactor, an issue was fixed and few optimizations were made: * abs() of minimum (negative) small int value is calculated properly. * objint_longlong and objint_mpz avoid allocating new object is the argument is already non-negative.
* all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriateDamien George2017-08-29
| | | | | | | The unary-op/binary-op enums are already defined, and there are no arithmetic tricks used with these types, so it makes sense to use the correct enum type for arguments that take these values. It also reduces code size quite a bit for nan-boxing builds.
* py/objcomplex: Remove unnecessary assignment of variable.Damien George2017-08-21

* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.

* py: Reduce str/repr precision of float numbers when floats are 30-bit.Damien George2017-04-21
| | | | | With 30-bit floats there aren't enough bits to faithfully print 7 decimal digits, so reduce the precision to 6 digits.
* py: Add very simple but correct hashing for float and complex numbers.Damien George2017-04-04
| | | | | | | | | | Hashing of float and complex numbers that are exact (real) integers should return the same integer hash value as hashing the corresponding integer value. Eg hash(1), hash(1.0) and hash(1+0j) should all be the same (this is how Python is specified: if x==y then hash(x)==hash(y)). This patch implements the simplest way of doing float/complex hashing by just converting the value to int and returning that value.
* py: Change mp_uint_t to size_t for mp_obj_str_get_data len arg.Damien George2017-03-29

* py/objcomplex: Fix typo in ternary expression.Damien George2017-02-04
| | | | | This typo actually did the correct thing, but it was very obscure (came about from think in terms of Python's "x if cond else y" expression).
* py/objcomplex: Correctly handle case of 0j to power of something.Damien George2017-02-03
| | | | | 0j to the power of negative now raises ZeroDivisionError, and 0j to the power of positive returns 0.
* py: Use mp_raise_msg helper function where appropriate.Damien George2016-10-17
| | | | | Saves the following number of bytes of code space: 176 for bare-arm, 352 for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.
* py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George2016-01-11
| | | | | | | | The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.
* py: Change type of .make_new and .call args: mp_uint_t becomes size_t.Damien George2016-01-11
| | | | | | | This patch changes the type signature of .make_new and .call object method slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more efficient when mp_uint_t is larger than a machine word. Doesn't affect ports when size_t and mp_uint_t have the same size.
* py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.Damien George2015-11-29
| | | | | | | | | This allows the mp_obj_t type to be configured to something other than a pointer-sized primitive type. This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts.
* py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky2015-10-11

* py: Implement mp_format_float for doubles and use where appropriatestijn2015-05-17
| | | | | | | This allows using (almost) the same code for printing floats everywhere, removes the dependency on sprintf and uses just snprintf and applies an msvc-specific fix for snprintf in a single place so nan/inf are now printed correctly.
* py: Fix printing of complex number when imaginary part is nanstijn2015-05-13

* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
* py: Combine load_attr and store_attr type methods into one (attr).Damien George2015-04-11
| | | | | | This simplifies the API for objects and reduces code size (by around 400 bytes on Thumb2, and around 2k on x86). Performance impact was measured with Pystone score, but change was barely noticeable.
* py: Parse big-int/float/imag constants directly in parser.Damien George2015-02-08
| | | | | | | | | 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.
* py: Fix cmath.log10; fix printing of complex number with negative imag.Damien George2015-02-02

* py, unix: Allow to compile with -Wunused-parameter.Damien George2015-01-20

* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py and libm: Add asinf,acosf; print higher precision for float.Damien George2014-09-11
| | | | | | Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851.
* py: Change all uint to mp_uint_t in obj.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George2014-08-30
| | | | Addressing issue #50, still some way to go yet.

* py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT.Paul Sokolovsky2014-06-20
| | | | | One thing is wanting to do 1 / 2 and get something else but 0, and quite another - doing rocket science ;-).
* Rename bultins config variables to MICROPY_PY_BUILTINS_*.Damien George2014-06-01
| | | | | | | | | | 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.
* py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.Damien George2014-05-21
| | | | See issue #608 for justification.
* py: Use mp_arg_check_num in more places.Damien George2014-05-11
| | | | | | | | | Updated functions now do proper checking that n_kw==0, and are simpler because they don't have to explicitly raise an exception. Down side is that the error messages no longer include the function name, but that's acceptable. Saves order 300 text bytes on x64 and ARM.
* 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, unix: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky2014-05-02
| | | | Specifically, nlr.h does.
