2016-02-23py/emitinlinethumb: Use qstrs instead of char* for names of asm ops.Damien George
Reduces code size by 112 bytes on Thumb2 arch, and makes assembler faster because comparison can be a simple equals instead of a string compare. Not all ops have been converted, only those that were simple to convert and reduced code size.
2016-01-27py/inlineasm: Add ability to specify return type of asm_thumb funcs.Damien George
Supported return types are: object, bool, int, uint. For example: @micropython.asm_thumb def foo(r0, r1) -> uint: add(r0, r0, r1)
2016-01-07py/inlinethumb: Remove 30-bit restriction on movwt instruction.Damien George
movwt can now move a full 32-bit constant into a register.
2016-01-07py/inlinethumb: Allow assembler to use big ints as args to instructions.Damien George
2015-12-10py/emitinlinethumb: Add support for MRS instruction.Henrik Sölver
Only IPSR and BASEPRI special registers supported at the moment, but easy to extend in the future.
2015-11-29py: Change qstr_* functions to use size_t as the type for str len arg.Damien George
2015-11-13py: Add constant table to bytecode.Damien George
Contains just argument names at the moment but makes it easy to add arbitrary constants.
2015-11-13py: Put all bytecode state (arg count, etc) in bytecode.Damien George
2015-11-09py/emitinlinethumb: Allow to compile with -Wsign-compare.Damien George
2015-10-31py: In inline asm, vldr and vstr offsets now in bytes not words.adminpete
As per ARM convention.
2015-10-19py: Add lsl/lsr/asr opcode support to inline Thumb2 assembler.Damien George
2015-10-16py: Add option for inline assembler to support ARMv7-M instructions.Damien George
Cortex-M0, M0+ and M1 only have ARMv6-M Thumb/Thumb2 instructions. M3, M4 and M7 have a superset of these, named ARMv7-M. This patch adds a config option to enable support of the superset of instructions.
2015-04-19py/inlinethumb: Support for core floating point instructions.=
Adds support for the following Thumb2 VFP instructions, via the option MICROPY_EMIT_INLINE_THUMB_FLOAT: vcmp vsqrt vneg vcvt_f32_to_s32 vcvt_s32_to_f32 vmrs vmov vldr vstr vadd vsub vmul vdiv
2015-04-16py: Add %q format support to mp_[v]printf, and use it.Damien George
2015-04-11py: In emitinlinethumb, use qstr_data instead of qstr_str and strlen.Damien George
2015-04-07py: Implement full func arg passing for native emitter.Damien George
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.

2015-02-13py: Make inline assembler raise proper SyntaxError exception on error.Damien George
Also gives line number of location of error. Very useful!
2015-02-12py: Add ldrex and strex to thumb2 inline assembler.Damien George
These are useful for implementing atomic lock operations.

2014-05-10py: Combine native emitters to 1 glue function; distinguish viper.Damien George
This patch simplifies the glue between native emitter and runtime, and handles viper code like inline assember: return values are converted to Python objects. Fixes issue #531.
2014-05-07py, compiler: Improve passes; add an extra pass for native emitter.Damien George
2014-05-03Add license header to (almost) all files.Damien George
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/.
2014-04-27py: Implement keyword-only args.Damien George
Implements 'def f(*, a)' and 'def f(*a, b)', but not default keyword-only args, eg 'def f(*, a=1)'. Partially addresses issue #524.
2014-04-26Add ARRAY_SIZE macro, and use it where possible.Damien George
2014-04-21py: Add 'align' and 'data' meta-instructions to inline assembler.Damien George
2014-04-18inlinethumb: Add wfi, cpsid and cpsie instructions.Damien George
2014-04-13py: Remove unique_codes from emitglue.c. Replace with pointers.Damien George
Attempt to address issue #386. unique_code_id's have been removed and replaced with a pointer to the "raw code" information. This pointer is stored in the actual byte code (aligned, so the GC can trace it), so that raw code (ie byte code, native code and inline assembler) is kept only for as long as it is needed. In memory it's now like a tree: the outer module's byte code points directly to its children's raw code. So when the outer code gets freed, if there are no remaining functions that need the raw code, then the children's code gets freed as well. This is pretty much like CPython does it, except that CPython stores indexes in the byte code rather than machine pointers. These indices index the per-function constant table in order to find the relevant code.
2014-04-13py: Big improvements to inline assembler.Damien George
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.
