2014-09-06py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch.Damien George
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.
2014-09-05py: Convert (u)int to mp_(u)int_t in mpz, and remove unused function.Damien George
2014-09-05py: Use % str formatting instead of {} in makeqstrdata.py.Damien George
Script is equivalent, but now also runs under ancient Python 2.6. Goes part way to addressing issue #847.
2014-09-04py: Use variable length encoded uints in more places in bytecode.Damien George
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.
2014-09-03Code style/whitespace cleanup; remove obsolete headers.Damien George
And move the MAP_ANON redefinition from py/asmx64.c to unix/alloc.c.
2014-09-03unix: Auto-detect MICROPY_EMIT_X64 and MICROPY_GCREGS_SETJMP.Damien George
If not set, MICROPY_EMIT_X64 is set only if on x86-64 machine. If not set, MICROPY_GCREGS_SETJMP is set when on MIPS.

2014-09-01Declare do_str() function before the implementationChris Dearman
This ensures that GCC does not discard the do_str implementation in some cases eg when compiling tests with debug enabled: make RUN_TESTS=1 DEBUG=1
2014-09-01stmhal, modwiznet5k: Add very minimal documentation.Damien George
2014-09-01stmhal: Add wiznet5k module, to control WIZnet ethernet adaptor.Damien George
Allows to create socket objects that support TCP and UDP in server and client mode. Interface is very close to standard Python socket class, except bind and accept do not work the same (due to hardware not supporting them in the usual way). Not compiled by default. To compile this module, use: make MICROPY_PY_WIZNET5K=1

Thanks to Artur Wroblewski for some suggested changes. I also added the TIPs section at the end while I was updating.

Addressing issue #50, still some way to go yet.
2014-08-29lib, libm: Add back dummy definition of tanf.Damien George
2014-08-29lib: Add lib and libm, moving current files from stmhal.Damien George
Top-level lib directory is for standard C libraries that we want to provide our own versions of (for efficiency and stand-alone reasons). It currently has libm in it for math functions. Also add atanf and atan2f, which addresses issue #837.
2014-08-29py: Use memmove instead of memcpy when appropriate.Damien George
Found this bug by running unix/ tests with DEBUG=1 enabled when compiling.
2014-08-29py: Fix 2 bugs in native emitter: jump_or_pop and stack settling.Damien George
Addresses issue #838.
2014-08-29py: Add compiler optimisation for conditions in parenthesis.Damien George

2014-08-29tests: Add option to run-tests to enable native emitter.Damien George
2014-08-28py: Move native glue code from runtime.c to new file nativeglue.c.Damien George
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.

Basic native ARM emitter
2014-08-28py, gc: Further reduce heap fragmentation with new, faster gc alloc.Damien George
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.
2014-08-28py: Reduce fragmentation of GC heap.Damien George
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.

2014-08-27py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.Damien George
Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since there is 1 less branch.
