Damien George 25d904105c py: Adjust regs for x86 so that 1 more local can live in a reg. 2014-09-06 23:24:32 +00:00
Damien George 91fe0d4880 unix: Fix modffi to be able to return double on x86 machines. 2014-09-06 23:04:42 +00:00
Damien George 03281b3850 py: Allow x86 native functions to take arguments. 
Fix some bugs with x86 stack and saving registers correctly.

Damien George c90f59ec3a py: Add support for emitting native x86 machine code. 2014-09-06 23:06:36 +01:00

Damien George c7a79284bb tests: Enable misc tests on pyboard; output 4 sig figs in rge_sm. 2014-09-06 18:38:55 +01:00
Damien George e6ce10a3e7 py: Native emitter now supports delete name & global, and end finally. 2014-09-06 18:38:20 +01:00
Paul Sokolovsky 78fde4819c modstruct: Implement 'O', 'P', 's' types for packed structs. 
This is required to deal with, well, packed C structs containing pointers.
 2014-09-06 20:22:06 +03:00
Paul Sokolovsky 722e562736 py: Correctly set sys.maxsize value for 64-bit. 
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.

Damien George 17598d49e1 unix: Don't use -Wno-error=cpp or #warning; fix strict alias warning. 
For the sake of older versions of gcc (and other compilers), don't use
the #warning CPP directive, nor the -Wno-error=cpp option.

Also, fix a strict alias warning in modffi.c for older compilers, and
add a test for ffi module.

Addresses issue #847.

Damien George 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.

Damien George afb1cf75dd py: Convert (u)int to mp_(u)int_t in mpz, and remove unused function. 2014-09-05 20:37:06 +01:00
Damien George 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.

Damien George 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.

Damien George dda46460ff Code style/whitespace cleanup; remove obsolete headers. 
And move the MAP_ANON redefinition from py/asmx64.c to unix/alloc.c.

Damien George 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.

Damien George 91fbea2c1e Merge pull request #845 from Vogtinator/master 
Add allocation macros (per platform) and ARM cache flush
 2014-09-03 22:31:08 +01:00
Fabian Vogt b7235b8412 Add cache flush in py/asmarm.c and add new MP_PLAT_ALLOC_EXEC and MP_PLAT_FREE_EXEC macros 
Fixes issue #840

Damien George bc9f34860b Merge branch 'msvc-extmod' of github.com:stinos/micropython into stinos-msvc-extmod 2014-09-02 11:37:47 +01:00
stijn 759138caee msvc: Exclude modtermios, include extmod and fix compilation error 2014-09-02 09:00:20 +02:00
Chris Dearman 8c56241c82 Declare do_str() function before the implementation 
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
