| | | | | | | | 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: 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: 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.

* 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

* 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.

* | py: Fix line number printing for file with 1 line.Damien George2014-08-26
|/ | | | | | | | | | With a file with 1 line (and an error on that line), used to show the line as number 0. Now shows it correctly as line number 1. But, when line numbers are disabled, it now prints line number 1 for any line that has an error (instead of 0 as previously). This might end up being confusing, but requires extra RAM and/or hack logic to make it print something special in the case of no line numbers.
* py: Add dispatch for user defined ==, >, <=, >=.Damien George2014-08-26
| | | | Addresses issue #827.
* stmhal: Make enable_irq and disable_irq inline functions.Damien George2014-08-25
| | | | | | | | | | | | These functions are generally 1 machine instruction, and are used in critical code, so makes sense to have them inline. Also leave these functions uninverted (ie 0 means enable, 1 means disable) and provide macro constants if you really need to distinguish the states. This makes for smaller code as well (combined with inlining). Applied to teensy port as well.

* py: Fix bug where GC collected native/viper/asm function data.Damien George2014-08-24
| | | | | | | | 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.
* py: Change hash and len members of str from 16 bit to full word.Damien George2014-08-22
| | | | | This allows to make strings longer than 64k. It doesn't use any more RAM with current GC because a str object still fits in a GC block.

* py: Speed up GC allocation.Damien George2014-08-22
