c7da7838ba tests: Add heapalloc.py.exp, since CPython can't generate it. 2014-10-31 22:09:40 +00:00

109c1de015 py: Make gc.enable/disable just control auto-GC; alloc is still allowed.
gc.enable/disable are now the same as CPython: they just control whether
automatic garbage collection is enabled or not.  If disabled, you can
still allocate heap memory, and initiate a manual collection.

e7a478204a py: Remove unused and unneeded SystemError exception.
It's purpose is for internal errors that are not catastrophic (ie not as
bad as RuntimeError).  Since we don't use it, we don't need it.

5a04e2cca8 tests: Add check for micropython.native and then skip relevant tests.
If micropython.native decorator doesn't compile, then we skill all
native/viper tests.

This patch also re-enables the ujson_loads test on NT.

Addresses issue #861, and partially addresses issue #856.

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.

3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

2ac4af6946 py: Allow viper to have type annotations.
Viper functions can now be annotated with the type of their arguments
and return value.  Eg:

@micropython.viper
def f(x:int) -> int:
    return x + 1

ffae48d750 py, compiler: Add basic support for A=const(123).
You can now do:

    X = const(123)
    Y = const(456 + X)

and the compiler will replace X and Y with their values.

See discussion in issue #266 and issue #573.
