Damien George 155fdc74d5 py/asm: Remove need for dummy_data when doing initial assembler passes.
For all but the last pass the assembler only needs to count how much space
is needed for the machine code, it doesn't actually need to emit anything.
The dummy_data just uses unnecessary RAM and without it the code is not
any more complex (and code size does not increase for Thumb and Xtensa
archs).

Damien George 63e82dcdfe py/asmthumb: Fix build for F7 MCUs after recent code refactoring. 2016-11-30 00:11:25 +11:00
Damien George 612599587b py: Factor out common code from assemblers into asmbase.[ch].
All assemblers should "derive" from mp_asm_base_t.

Antonin ENFRUN f3b19ef634 py/asmthumb: Flush D-cache, and invalidate I-cache on STM32F7.
Tested on a STM32F7DISCO at 216MHz.  All tests generating code (inlineasm,
native, viper) now pass, except pybnative/while.py, but that's because
there is no LED(2).

Damien George 723d598d32 py/asmthumb: Allow to compile with -Wsign-compare and -Wunused-parameter. 2015-11-09 14:11:21 +00:00
Damien George 9988618e0e py: Implement full func arg passing for native emitter.
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.

Damien George 67c5f89af5 py: In inline assembler, fix branch out-of-range error reporting.
Should only give an error on the last pass of the assembler, since
that's when we are certain about the branch size.

Damien George d9dc6fff21 py: Allocate memory for assembled code at start of PASS_EMIT.
Previously was allocating at end of PASS_COMPUTE, and this pass was
being run twice, so memory was being allocated twice.

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
2014-09-03 23:07:42 +02:00
Damien George 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.

Paul Sokolovsky 59c675a64c py: Include mpconfig.h before all other includes.
It defines types used by all other headers.

Fixes #691.

Damien George 9597771fe4 py, emitters: Fix dummy_data size for bytecode and thumb.
Thumb uses a bit less RAM, bytecode uses a tiny bit more, to avoid
overflow of the dummy buffer in certain cases.

Addresses issue #599.

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Damien George e5f8a77db6 py: Add 'align' and 'data' meta-instructions to inline assembler. 2014-04-21 13:33:15 +01:00
Damien George 90edf9e13b inlinethumb: Add wfi, cpsid and cpsie instructions. 2014-04-18 16:56:54 +01:00
Damien George 8721087661 py: Big improvements to inline assembler.
Improved the Thumb assembler back end.  Added many more Thumb
instructions to the inline assembler.  Improved parsing of assembler
instructions and arguments.  Assembler functions can now be passed the
address of any object that supports the buffer protocol (to get the
address of the buffer).  Added an example of how to sum numbers from
an array in assembler.

Damien George 6f355fd3b9 py: Make labels unsigned ints (converted from int).

reflects that.

Paul Sokolovsky 520e2f58a5 Replace global "static" -> "STATIC", to allow "analysis builds". Part 2. 2014-02-12 18:31:30 +02:00
Damien George e67ed5d285 Improve configurability for native x64/thumb emitter.
With MICROPY_EMIT_X64 and MICROPY_EMIT_THUMB disabled, the respective
emitters and assemblers will not be included in the code.  This can
significantly reduce binary size for unix version.

Damien 732407f1bf Change memory allocation API to require size for free and realloc. 2013-12-29 19:33:23 +00:00
Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
