Damien George c0bcf00ed1 py/asm*.c: Remove unnecessary check for num_locals<0 in asm entry func. 
All callers of the asm entry function guarantee that num_locals>=0, so no
need to add an explicit check for it.  Use an assertion instead.

Also, the signature of asm_x86_entry is changed to match the other asm
entry functions.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments 
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George 3235b95f08 py/asmx64: Support moving a 64-bit immediate to one of top 8 registers. 
If constants (eg mp_const_none_obj) are placed in very high memory
locations that require 64-bits for the pointer then the assembler must be
able to emit instructions to move such pointers to one of the top 8
registers (ie r8-r15).

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 612599587b py: Factor out common code from assemblers into asmbase.[ch]. 
All assemblers should "derive" from mp_asm_base_t.

Damien George 4dea922610 py: Adjust some spaces in code style/format, purely for consistency. 2015-04-09 15:29:54 +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 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.

Damien George 91cfd414c0 py: Implement native load for viper.

machine instructions.

 2014-09-29 22:44:18 +01:00
Damien George 3112cde900 py: Implement more binary ops for viper emitter. 
This included a bit of restructuring of the assembler backends.  Note
that the ARM backend is missing a few functions and won't compile.

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 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.
