* py: Add 'builtins' module.Damien George2014-09-17
|
* py: Add native json printing using existing print framework.Damien George2014-09-17
| | | | | Also add start of ujson module with dumps implemented. Enabled in unix and stmhal ports. Test passes on both.
* py: Make dict use a bit less RAM when iterating; properly del values.Damien George2014-09-17
| | | | | | | | Heap RAM was being allocated to print dicts and do some other types of iterating. Now these iterations use 1 word of state on the stack. Deleting elements from a dict was not allowing the value to be reclaimed by the GC. This is now fixed.
* py: Make asm_arm_less_op take destination register as first arg.Damien George2014-09-15
| | | | This gets ARM native emitter working againg and addresses issue #858.
* py: Move definition of mp_sys_exit to core.Damien George2014-09-15
| | | | | | | | sys.exit always raises SystemExit so doesn't need a special implementation for each port. If C exit() is really needed, use the standard os._exit function. Also initialise mp_sys_path and mp_sys_argv in teensy port.
* py: Fix build error when float disabled; add test for divmod.Damien George2014-09-13

* py: Implement divmod, % and proper // for floating point.Damien George2014-09-13
| | | | Tested and working on unix and pyboard.
* py: Load strings as objects when compiling viper.Damien George2014-09-12
| | | | | | | | | Eventually, viper wants to be able to use raw pointers to strings and arrays for efficient access. But for now, let's just load strings as a Python object so they can be used as normal. This will anyway be compatible with eventual intended viper behaviour. Addresses issue #857.
* 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.

| | | | Addresses issue #848.

| * modstruct: Implement 'O', 'P', 's' types for packed structs.Paul Sokolovsky2014-09-06
| | | | | | | | This is required to deal with, well, packed C structs containing pointers.
| * py: Correctly set sys.maxsize value for 64-bit.Paul Sokolovsky2014-09-06
| | | | | | | | | | | | Type representing signed size doesn't have to be int, so use special value which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather by POSIX), allow ports to set it.

* py: Fix definition of sys.maxsize with mpz changes.Damien George2014-09-06
|
* py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch.Damien George2014-09-06
| | | | | | | | | | | | | | | | Previously, mpz was restricted to using at most 15 bits in each digit, where a digit was a uint16_t. With this patch, mpz can use all 16 bits in the uint16_t (improvement to mpn_div was required). This gives small inprovements in speed and RAM usage. It also yields savings in ROM code size because all of the digit masking operations become no-ops. Also, mpz can now use a uint32_t as the digit type, and hence use 32 bits per digit. This will give decent improvements in mpz speed on 64-bit machines. Test for big integer division added.
* py: Convert (u)int to mp_(u)int_t in mpz, and remove unused function.Damien George2014-09-05

* py: Use % str formatting instead of {} in makeqstrdata.py.Damien George2014-09-05
| | | | | Script is equivalent, but now also runs under ancient Python 2.6. Goes part way to addressing issue #847.
* py: Use variable length encoded uints in more places in bytecode.Damien George2014-09-04
| | | | | | 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.
* Code style/whitespace cleanup; remove obsolete headers.Damien George2014-09-03

* 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: Use memmove instead of memcpy when appropriate.Damien George2014-08-29
| | | | | Found this bug by running unix/ tests with DEBUG=1 enabled when compiling.

| | | | | | | Optimises: if () -> if False if (x,...) -> if True if (a and b) -> if a and b
* py: Move native glue code from runtime.c to new file nativeglue.c.v1.3.1Damien George2014-08-28
| | | | | | | | This way, the native glue code is only compiled if native code is enabled (which makes complete sense; thanks to Paul Sokolovsky for the idea). Should fix issue #834.

* | py, gc: Further reduce heap fragmentation with new, faster gc alloc.Damien George2014-08-28
| | | | | | | | | | | | | | | | | | | | | | The heap allocation is now exactly as it was before the "faster gc alloc" patch, but it's still nearly as fast. It is fixed by being careful to always update the "last free block" pointer whenever the heap changes (eg free or realloc). Tested on all tests by enabling EXTENSIVE_HEAP_PROFILING in py/gc.c: old and new allocator have exactly the same behaviour, just the new one is much faster.
* | py: Reduce fragmentation of GC heap.Damien George2014-08-28
|/ | | | | | | | | | | Recent speed up of GC allocation made the GC have a fragmented heap. This patch restores "original fragmentation behaviour" whilst still retaining relatively fast allocation. This patch works because there is always going to be a single block allocated now and then, which advances the gc_last_free_atb_index pointer often enough so that the whole heap doesn't need scanning. Should address issue #836.
* py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.Damien George2014-08-27
| | | | | Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since there is 1 less branch.
