* py/gc: When printing info, use %u instead of UINT_FMT for size_t args.Damien George2015-12-18
| | | | | | | | | | Ideally we'd use %zu for size_t args, but that's unlikely to be supported by all runtimes, and we would then need to implement it in mp_printf. So simplest and most portable option is to use %u and cast the argument to uint(=unsigned int). Note: reason for the change is that UINT_FMT can be %llu (size suitable for mp_uint_t) which is wider than size_t and prints incorrect results.
* py: Add MICROPY_ENABLE_COMPILER and MICROPY_PY_BUILTINS_EVAL_EXEC opts.Damien George2015-12-18
| | | | | | | | | | | | MICROPY_ENABLE_COMPILER can be used to enable/disable the entire compiler, which is useful when only loading of pre-compiled bytecode is supported. It is enabled by default. MICROPY_PY_BUILTINS_EVAL_EXEC controls support of eval and exec builtin functions. By default they are only included if MICROPY_ENABLE_COMPILER is enabled. Disabling both options saves about 40k of code size on 32-bit x86.
* py/emitglue: Add include of unistd.h for read function.Damien George2015-12-18

* py/compile: Simplify compilation of comprehension iterators.Damien George2015-12-18
| | | | Saves 88 bytes on Thumb2, and 200 bytes on x86-64 archs.
* ports: Rename "machine" module to "umachine".Paul Sokolovsky2015-12-18
| | | | | | | | To let unix port implement "machine" functionality on Python level, and keep consistent naming in other ports (baremetal ports will use magic module "symlinking" to still load it on "import machine"). Fixes #1701.
* py/parse: Include stddef.h for definition of size_t.Damien George2015-12-17
|
* py/modgc: Remove obsolete extern declaration.Damien George2015-12-17
|
* py/compile: Use size_t or uintptr_t instead of mp_uint_t.Damien George2015-12-17
|
* py/parse: Replace mp_int_t/mp_uint_t with size_t etc, where appropriate.Damien George2015-12-17
|
* py/qstr: Change type of qstr from mp_uint_t to size_t.Damien George2015-12-17
| | | | | | | | | | For builds where mp_uint_t is larger than size_t, it doesn't make sense to use such a wide type for qstrs. There can only be as many qstrs as there is address space on the machine, so size_t is the correct type to use. Saves about 3000 bytes of code size when building unix/ port with MICROPY_OBJ_REPR_D.
* py/qstr: Use size_t instead of mp_uint_t when counting allocated bytes.Damien George2015-12-17
|
* py/bc: Use size_t instead of mp_uint_t to count size of state and args.Damien George2015-12-17
|
* py: Fix MICROPY_STACKLESS mode to compile with MICROPY_OBJ_REPR_D.Damien George2015-12-17
|
* py/mpprint: Implement %llu and %lld format specifiers for mp_printf.Damien George2015-12-17
| | | | Only enabled for MICROPY_OBJ_REPR_D.
* py/gc: Use size_t instead of mp_uint_t to count things related to heap.Damien George2015-12-16
| | | | | | | size_t is the correct type to use to count things related to the size of the address space. Using size_t (instead of mp_uint_t) is important for the efficiency of ports that configure mp_uint_t to larger than the machine word size.
* py/gc: For finaliser, interpret a pointer into the heap as concrete obj.Damien George2015-12-16
|
* py/gc: Scan GC blocks as an array of pointers, not an array of objects.Damien George2015-12-16
| | | | | | The GC should search for pointers within the heap. This patch makes a difference when an object is larger than a pointer (eg 64-bit NaN boxing).
* py/modsys: Fix module globals table to use MP_ROM_QSTR.Damien George2015-12-16
|
* py/objpolyiter: Implement instance-polymorphic iterator type.Paul Sokolovsky2015-12-14
| | | | | | | This allows to have single itertaor type for various internal iterator types (save rodata space by not having repeating almost-empty type structures). It works by looking "iternext" method stored in particular object instance (should be first object field after "base").
* unix: Move modmachine into unix directoryDave Hylands2015-12-13
| | | | | This leaves behind the common functionality in extmod/machine_mem.c which can be used by all ports.
* py/modmath: Add domain error checking to sqrt, log, log2, log10.Michael Buesch2015-12-12
| | | | | These functions will raise 'ValueError: math domain error' on invalid input.
* py: Fix compiler to handle lambdas used as default arguments.Damien George2015-12-12
| | | | Addresses issue #1709.
* py: Make UNARY_OP_NOT a first-class op, to agree with Py not semantics.Damien George2015-12-10
| | | | | | | | | | | | | | | Fixes #1684 and makes "not" match Python semantics. The code is also simplified (the separate MP_BC_NOT opcode is removed) and the patch saves 68 bytes for bare-arm/ and 52 bytes for minimal/. Previously "not x" was implemented as !mp_unary_op(x, MP_UNARY_OP_BOOL), so any given object only needs to implement MP_UNARY_OP_BOOL (and the VM had a special opcode to do the ! bit). With this patch "not x" is implemented as mp_unary_op(x, MP_UNARY_OP_NOT), but this operation is caught at the start of mp_unary_op and dispatched as !mp_obj_is_true(x). mp_obj_is_true has special logic to test for truthness, and is the correct way to handle the not operation.
* py/emitinlinethumb: Add support for MRS instruction.Henrik Sölver2015-12-10
| | | | | Only IPSR and BASEPRI special registers supported at the moment, but easy to extend in the future.
* py/mkrules.mk: Don't pass COPT to linker.Paul Sokolovsky2015-12-10
| | | | | | Oftentimes, libc, libm, etc. don't come compiled with CPU compressed code option (Thumb, MIPS16, etc.), but we may still want to use such compressed code for MicroPython itself.

* py: Fix calling of parent classmethod from instance of subclass.Damien George2015-12-09

| | | | Addresses issue #1693.

* py: Make it easy to build without MICROPY_PY_BUILTINS_COMPLEX.Paul Sokolovsky2015-12-07
| | | | Automagically skip related modules.
* py/modsys: Use MP_ROM_PTR() initializer for sys.modules.Paul Sokolovsky2015-12-05
| | | | Based on similar usage for sys.argv/sys.path.
* py/modsys: Implement sys.modules.Paul Sokolovsky2015-12-05
| | | | | This for example will allow people to reload modules which didn't load successfully (e.g. due to syntax error).

|
* py/mpprint: Printing of doubles is now supported (by uPy own routine).fabien.lementec2015-12-02
|
* py: Add support for 64-bit NaN-boxing object model, on 32-bit machine.Damien George2015-11-29
| | | | | | | | | | | | | To use, put the following in mpconfigport.h: #define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D) #define MICROPY_FLOAT_IMPL (MICROPY_FLOAT_IMPL_DOUBLE) typedef int64_t mp_int_t; typedef uint64_t mp_uint_t; #define UINT_FMT "%llu" #define INT_FMT "%lld" Currently does not work with native emitter enabled.
* 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: Add MP_ROM_* macros and mp_rom_* types and use them.Damien George2015-11-29
|
* py/gc: Move away from using mp_uint_t, instead use uintptr_t and size_t.Damien George2015-11-29
| | | | The GC works with concrete pointers and so the types should reflect this.
