For example, ussl can come from axtls or mbedtls. If neither are enabled
then don't try and set an empty definition twice, and only include it
once in MICROPY_REGISTERED_MODULES.

Now that constant tuples are supported in the parser, eg (1, True, "str"),
it's a small step to allow anything that is a constant to be used with the
pattern:
from micropython import const
X = const(obj)
This commit makes the required changes to allow the following types of
constants:
from micropython import const
_INT = const(123)
_FLOAT = const(1.2)
_COMPLEX = const(3.4j)
_STR = const("str")
_BYTES = const(b"bytes")
_TUPLE = const((_INT, _STR, _BYTES))
_TUPLE2 = const((None, False, True, ..., (), _TUPLE))
Prior to this, only integers could be used in const(...).

Because the test modifies the (now) bytearray object, and if it's a bytes
object it's not guaranteed that it can be modified, or that this constant
object isn't used elsewhere.

The recent rework of bytecode made all constants global with respect to the
module (previously, each function had its own constant table). That means
the constant table for a module is shared among all functions/methods/etc
within the module.
This commit add support to the compiler to de-duplicate constants in this
module constant table. So if a constant is used more than once -- eg 1.0
or (None, None) -- then the same object is reused for all instances.
For example, if there is code like `print(1.0, 1.0)` then the parser will
create two independent constants 1.0 and 1.0. The compiler will then (with
this commit) notice they are the same and only put one of them in the
constant table. The bytecode will then reuse that constant twice in the
print expression. That allows the second 1.0 to be reclaimed by the GC,
also means the constant table has one less entry so saves a word.

To make sure there are no dangling references to the lists, and the GC can
reclaim heap memory.

Prior to this commit, all qstrs were required to be allocated (by calling
mp_emit_common_use_qstr) in the MP_PASS_SCOPE pass (the first one). But
this is an unnecessary restriction, which is lifted by this commit.
Lifting the restriction simplifies the compiler because it can allocate
qstrs in later passes.
This also generates better code, because in some cases (eg when a variable
is closed over) the scope of an identifier is not known until a bit later
and then the identifier no longer needs its qstr allocated in the global
table.
Code size is reduced for all ports with this commit.

Some architectures (like esp32 xtensa) cannot read byte-wise from
executable memory. This means the prelude for native functions -- which is
usually located after the machine code for the native function -- must be
placed in separate memory that can be read byte-wise. Prior to this commit
this was achieved by enabling N_PRELUDE_AS_BYTES_OBJ for the emitter and
MICROPY_EMIT_NATIVE_PRELUDE_AS_BYTES_OBJ for the runtime. The prelude was
then placed in a bytes object, pointed to by the module's constant table.
This behaviour is changed by this commit so that a pointer to the prelude
is stored either in mp_obj_fun_bc_t.child_table, or in
mp_obj_fun_bc_t.child_table[num_children] if num_children > 0. The reasons
for doing this are:
1. It decouples the native emitter from runtime requirements, the emitted
code no longer needs to know if the system it runs on can/can't read
byte-wise from executable memory.
2. It makes all ports have the same emitter behaviour, there is no longer
the N_PRELUDE_AS_BYTES_OBJ option.
3. The module's constant table is now used only for actual constants in the
Python code. This allows further optimisations to be done with the
constants (eg constant deduplication).
Code size change for those ports that enable the native emitter:
unix x64: +80 +0.015%
stm32: +24 +0.004% PYBV10
esp8266: +88 +0.013% GENERIC
esp32: -20 -0.002% GENERIC[incl -112(data)]
rp2: +32 +0.005% PICO

mpy-cross will now generate native code based on the size of
mp_code_state_native_t, and the runtime will use this struct to calculate
the offset of the .state field. This makes native code generation and
execution (which rely on this struct) independent to the settings
MICROPY_STACKLESS and MICROPY_PY_SYS_SETTRACE, both of which change the
size of the mp_code_state_t struct.
Fixes issue #5059.

Prior to this commit, even with unicode disabled .py and .mpy files could
contain unicode characters, eg by entering them directly in a string as
utf-8 encoded.
The only thing the compiler disallowed (with unicode disabled) was using
\uxxxx and \Uxxxxxxxx notation to specify a character within a string with
value >= 0x100; that would give a SyntaxError.
With this change mpy-cross will now accept \u and \U notation to insert a
character with value >= 0x100 into a string (because the -mno-unicode
option is now gone, there's no way to forbid this). The runtime will
happily work with strings with such characters, just like it already works
with strings with characters that were utf-8 encoded directly.
This change simplifies things because there are no longer any feature
flags in .mpy files, and any bytecode .mpy will now run on any target.

Replace the timer-based sleep with the standard win32 call since the former
has no benefits: even though it allows specifying the time in 100uSec
chunks, the actual resolution is still limited by the OS and is never
better than 1mSec.
For clarity move all of this next to the mp_hal_delay_ms definition so all
related functions are in one place.
|
|
Non-real-time systems like Windows, Linux and macOS do not have reliable
timing, so increase the sleep intervals to make these tests more likely to
pass.

This replaces occurences of
foo_t *foo = m_new_obj(foo_t);
foo->base.type = &foo_type;
with
foo_t *foo = mp_obj_malloc(foo_t, &foo_type);
Excludes any places where base is a sub-field or when new0/memset is used.

This is to replace the following:
mp_foo_obj_t *self = m_new_obj(mp_foo_obj_t);
self->base.type = &mp_type_foo;
with:
mp_foo_obj_t *self = mp_obj_malloc(mp_foo_obj_t, &mp_type_foo);
Calling the function is less code than inlining setting the type
everywhere, adds up to ~100 bytes on PYBV11.
It also helps to avoid an easy mistake of forgetting to set the type.
