Fabian Vogt e5268963c6 Implement missing ARM emitter functions for viper 2014-10-04 00:57:21 +02:00
Damien George 00be7a849a py: Fix unix-cpy to compile with uint->mp_uint_t changes. 2014-10-03 20:05:44 +01:00
Damien George 39dc145478 py: Change [u]int to mp_[u]int_t in qstr.[ch], and some other places.
This should pretty much resolve issue #50.

Damien George 42f3de924b py: Convert [u]int to mp_[u]int_t where appropriate.
Addressing issue #50.

Damien George 8b03d944e2 py: Remove IOError since it's deprecated; use OSError instead.
In CPython IOError (and EnvironmentError) is deprecated and aliased to
OSError.  All modules that used to raise IOError now raise OSError (or a
derived exception).

In Micro Python we never used IOError (except 1 place, incorrectly) and
so don't need to keep it.

See http://legacy.python.org/dev/peps/pep-3151/ for background.

Damien George 1c6a1dc740 py: Allow x86-64 to mov r16 to rm16 with extended src reg.
Fixes bug with x86-64 viper ptr16.

Damien George dfef4249eb py: Fix viper store on x86; add tests for viper ptr16. 2014-09-29 21:41:41 +00:00
Damien George e9dac3b4d0 py: Add casting to viper; add native mem stores to viper.
Viper can now do the following:

def store(p:ptr8, c:int):
    p[0] = c

This does a store of c to the memory pointed to by p using a machine
instructions inline in the code.

Damien George 3112cde900 py: Implement more binary ops for viper emitter.
This included a bit of restructuring of the assembler backends.  Note
that the ARM backend is missing a few functions and won't compile.

Damien George 6f81348fa2 py: Allow viper to use ints as direct conditionals in jumps.

bvernoux f6f248b464 Fix error: unknown type name 'size_t' 2014-09-28 09:54:35 +02:00
Damien George 133b083b89 py: Clean up nlr*.S to make it easier to read; fix clang .bss error.
It seems that newer versions of clang don't like the .bss directive, so
we don't use it for OSX.

Addressing issues #865 and #875.

Damien George cde0ca21bf py: Simplify JSON str printing (while still conforming to JSON spec).
The JSON specs are relatively flexible and allow us to use one function
to print strings, be they ascii, bytes or utf-8 encoded.

Damien George 4bcd04bcad py: Tidy up exception matching; allow matching of tuple of exceptions.
Addresses issue #864.

Damien George b0261341d3 py: For malloc and vstr functions, use size_t exclusively for int type.
It seems most sensible to use size_t for measuring "number of bytes" in
malloc and vstr functions (since that's what size_t is for).  We don't
use mp_uint_t because malloc and vstr are not Micro Python specific.

Damien George 52b5d76a6b py: Free non-interned strings in the parser when not needed.
mp_parse_node_free now frees the memory associated with non-interned
strings.  And the parser calls mp_parse_node_free when discarding a
non-used node (such as a doc string).

Also, the compiler now frees the parse tree explicitly just before it
exits (as opposed to relying on the caller to do this).

Addresses issue #708 as best we can.

Damien George d6230f62c7 py: Make native emitter handle multi-compare and not/is not/not in ops. 2014-09-23 14:15:45 +00:00
Damien George eaaebf3291 stmhal: Initialise stack pointer correctly.
Stack is full descending and must be 8-byte aligned.  It must start off
pointing to just above the last byte of RAM.

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

Addresses issue #872 (among many other undiscovered issues).

Damien George 612045f53f py: Add native json printing using existing print framework.
Also add start of ujson module with dumps implemented.  Enabled in unix
and stmhal ports.  Test passes on both.

Damien George 8a9b999f1c py: Make dict use a bit less RAM when iterating; properly del values.
Heap RAM was being allocated to print dicts and do some other types of
iterating.  Now these iterations use 1 word of state on the stack.

Deleting elements from a dict was not allowing the value to be reclaimed
by the GC.  This is now fixed.

Damien George d4a799f152 py: Make asm_arm_less_op take destination register as first arg.
This gets ARM native emitter working againg and addresses issue #858.

Damien George b92cbe6129 py: Move definition of mp_sys_exit to core.
sys.exit always raises SystemExit so doesn't need a special
implementation for each port.  If C exit() is really needed, use the
standard os._exit function.

Also initialise mp_sys_path and mp_sys_argv in teensy port.

Damien George 8594ce2280 py: Implement divmod, % and proper // for floating point.
Tested and working on unix and pyboard.

Damien George bb29546868 py: Load strings as objects when compiling viper.
Eventually, viper wants to be able to use raw pointers to strings and
arrays for efficient access.  But for now, let's just load strings as a
Python object so they can be used as normal.  This will anyway be
compatible with eventual intended viper behaviour.

Addresses issue #857.

Damien George 20beff9ae3 py and libm: Add asinf,acosf; print higher precision for float.
Also use less stack space when printing single precision float.

Addition of asinf and acosf addresses issue #851.

Paul Sokolovsky 78fde4819c modstruct: Implement 'O', 'P', 's' types for packed structs.
This is required to deal with, well, packed C structs containing pointers.

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.
