9aeba3e41b py/binary: Add missing "break" statements. 2017-07-04 02:11:46 +10:00

6cfa61a4cc py/binary: Handle storing big-ints to all arrays types. 
Prior to this patch only 'q' and 'Q' type arrays could store big-int
values.  With this patch any big int that is stored to an array is handled
by the big-int implementation, regardless of the typecode of the array.
This allows arrays to work with all type sizes on all architectures.

af90461931 py/binary: mp_binary_get_size: Raise error on unsupported typecodes. 
Previouly, we had errors checked in callers, which led to duplicate code
or missing checks in some places.

999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR. 
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.

91fc075a33 py/objarray: Allow to create array of void pointers, as extension to CPython. 
Using 'P' format specifier (matches struct module). This is another shortcut
for FFI, just as previously introduced "array of objects" ('O').

271d18eb08 py: Support conversion of bignum to bytes. 
This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.

Addresses issue #1155.

be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack. 
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.

Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.

Addresses issues #779 and #998.

04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

e9db840480 py: Start implementing "struct" module. 
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.
