This patch refactors some code so that it is easier to integrate new
inline assemblers for different architectures other than ARM Thumb.
py/viper: Allow casting of Python integers to viper pointers.2016-02-09T13:29:20+00:00Damien Georgedamien.p.george@gmail.com2016-02-09T13:29:20+00:00urn:sha1:3e02b1d19a4b1fb36ee36b0d43144bad6b797f2f
This allows you to pass a number (being an address) to a viper function
that expects a pointer, and also allows casting of integers to pointers
within viper functions.
This was actually the original behaviour, but it regressed due to native
type identifiers being promoted to 4 bits in width.
py: Extend native type-sig to use 4 bits, so uint is separate to ptr.2016-02-02T23:16:05+00:00Damien Georgedamien.p.george@gmail.com2016-02-02T23:16:05+00:00urn:sha1:5f3e005b6791634b104fa6385c8a9bf5ed1af164
Before this patch, the native types for uint and ptr/ptr8/ptr16/ptr32
all overlapped and it was possible to make a mistake in casting. Now,
these types are all separate and any coding mistakes will be raised
as runtime errors.
py/inlineasm: Add ability to specify return type of asm_thumb funcs.2016-01-27T14:27:10+00:00Damien Georgedamien.p.george@gmail.com2016-01-15T15:20:43+00:00urn:sha1:8f54c08691faa3dd859852d211230fd7d9791abd
Supported return types are: object, bool, int, uint.
For example:
@micropython.asm_thumb
def foo(r0, r1) -> uint:
add(r0, r0, r1)
py/viper: Truncate viper integer args so they can be up to 32-bit.2016-01-07T16:48:20+00:00Damien Georgedamien.p.george@gmail.com2016-01-07T16:48:20+00:00urn:sha1:dd0a0f79d777684aba7986d44fae1a6eff176151py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.2015-10-11T12:18:15+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-10-11T09:09:43+00:00urn:sha1:1b586f3a734c27c78080fb2173bbde17168cb9e4py: Remove mp_load_const_bytes and instead load precreated bytes object.2015-06-25T14:42:13+00:00Damien Georgedamien.p.george@gmail.com2015-06-25T14:42:13+00:00urn:sha1:59fba2d6ea31c134c9c0b88dc73cd25b236f167c
Previous to this patch each time a bytes object was referenced a new
instance (with the same data) was created. With this patch a single
bytes object is created in the compiler and is loaded directly at execute
time as a true constant (similar to loading bignum and float objects).
This saves on allocating RAM and means that bytes objects can now be
used when the memory manager is locked (eg in interrupts).
The MP_BC_LOAD_CONST_BYTES bytecode was removed as part of this.
Generated bytecode is slightly larger due to storing a pointer to the
bytes object instead of the qstr identifier.
Code size is reduced by about 60 bytes on Thumb2 architectures.

This patch gets full function argument passing working with native
emitter. Includes named args, keyword args, default args, var args
and var keyword args. Fully Python compliant.
It reuses the bytecode mp_setup_code_state function to do all the hard
work. This function is slightly adjusted to accommodate native calls,
and the native emitter is forced a bit to emit similar prelude and
code-info as bytecode.
