8002d5d2b9 py: Fix definition of sys.maxsize with mpz changes. 2014-09-06 17:37:29 +01:00
Damien George
9a21d2e070 py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch. 
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.

e191d42188 py: Use % str formatting instead of {} in makeqstrdata.py. 
Script is equivalent, but now also runs under ancient Python 2.6.
Goes part way to addressing issue #847.

b534e1b9f1 py: Use variable length encoded uints in more places in bytecode. 
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.

a669cbc690 unix: Auto-detect MICROPY_EMIT_X64 and MICROPY_GCREGS_SETJMP. 
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.

bcf041f1a3 stmhal: Add wiznet5k module, to control WIZnet ethernet adaptor. 
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

8707ea3421 lib: Add lib and libm, moving current files from stmhal. 
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.

110ba35980 py: Move native glue code from runtime.c to new file nativeglue.c. 
This way, the native glue code is only compiled if native code is

the idea).

Should fix issue #834.

516b09efc3 py, gc: Further reduce heap fragmentation with new, faster gc alloc. 
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.

b796e3d848 py: Reduce fragmentation of GC heap. 
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.
