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 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).

Paul Sokolovsky 351424e719 emitnative: Revamp ARM codegen compile after full-arg support refactors.
The code was apparently broken after 9988618e0e
"py: Implement full func arg passing for native emitter.". This attempts to
propagate those changes to ARM emitter.

Damien George 4dea922610 py: Adjust some spaces in code style/format, purely for consistency. 2015-04-09 15:29:54 +00:00
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 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.
