Paul Sokolovsky 403c93053e py/mpconfig.h: Enable MICROPY_PY_SYS_EXIT by default.
sys.exit() is an important function to terminate a program. In particular,
the testsuite relies on it to skip tests (i.e. any other functionality may
be disabled, but sys.exit() is required to at least report that properly).

Paul Sokolovsky ee7ad7e8be esp8266: Add "ota" target to produce firmware binary for use with yaota8266.
https://github.com/pfalcon/yaota8266 is a (WIP) OTA-enabled bootloader
which doesn't require reserving space 2x size of a firmware.

Damien George e8f2db7da3 py/runtime: Zero out fs_user_mount array in mp_init.
There's no need to force ports to copy-and-paste this initialisation
code.  If FSUSERMOUNT is enabled then this zeroing out must be done.

Damien George d9047d3c8a py/builtinimport: Support importing packages from compiled .mpy files.
This patch ensures that __init__.mpy files are imported if their
containing directory is imported as a package.

Damien George a3c61004c2 py/binary: Do zero extension when storing a value larger than word size. 2016-12-12 15:00:06 +11:00
Paul Sokolovsky aee13ef3f2 tests: Update for required byteorder arg for int.from_bytes()/to_bytes(). 2016-12-09 22:53:30 +03:00
Paul Sokolovsky 9d787de2a1 py/objint: from_bytes, to_bytes: Require byteorder arg, require "little".
CPython requires byteorder arg, make uPy compatible. As we support only
"little", error out on anything else.

Damien George 93ee6603b1 py/asm: Fix x86 and ARM assemblers due to recent code refactoring. 2016-12-09 22:54:45 +11:00
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 e920bab976 py/emitinline: Move common code for end of final pass to compiler.
This patch moves some common code from the individual inline assemblers to
the compiler, the code that calls the emit-glue to assign the machine code
to the functions scope.

Damien George dd53b12193 py/emitinline: Move inline-asm align and data methods to compiler.
These are generic methods that don't depend on the architecture and so
can be handled directly by the compiler.

Damien George a7fd786a1f py/emitinline: Embed entire asm struct instead of a pointer to it.
This reduces fragmentation, and memory use by 1 word.  But more
importantly it means the emit_inline_asm_t struct now "derives" from
mp_asm_base.

Damien George 3a4ebf5768 esp8266: Enable inline Xtensa assembler.
With this patch, @micropython.asm_xtensa can be used on the esp8266 port.

Damien George f76b1bfa9f py: Add inline Xtensa assembler.
This patch adds the MICROPY_EMIT_INLINE_XTENSA option, which, when
enabled, allows the @micropython.asm_xtensa decorator to be used.

The following opcodes are currently supported (ax is a register, a0-a15):

    ret_n()
    callx0(ax)
    j(label)
    jx(ax)

    beqz(ax, label)
    bnez(ax, label)
    mov(ax, ay)
    movi(ax, imm) # imm can be full 32-bit, uses l32r if needed

    and_(ax, ay, az)
    or_(ax, ay, az)
    xor(ax, ay, az)
    add(ax, ay, az)
    sub(ax, ay, az)
    mull(ax, ay, az)

    l8ui(ax, ay, imm)
    l16ui(ax, ay, imm)
    l32i(ax, ay, imm)
    s8i(ax, ay, imm)
    s16i(ax, ay, imm)
    s32i(ax, ay, imm)
    l16si(ax, ay, imm)
    addi(ax, ay, imm)

    ball(ax, ay, label)
    bany(ax, ay, label)
    bbc(ax, ay, label)
    bbs(ax, ay, label)
    beq(ax, ay, label)
    bge(ax, ay, label)
    bgeu(ax, ay, label)
    blt(ax, ay, label)
    bnall(ax, ay, label)
    bne(ax, ay, label)
    bnone(ax, ay, label)

Upon entry to the assembly function the registers a0, a12, a13, a14 are
pushed to the stack and the stack pointer (a1) decreased by 16.  Upon
exit, these registers and the stack pointer are restored, and ret.n is
executed to return to the caller (caller address is in a0).

Note that the ABI for the Xtensa emitters is non-windowing.

Damien George ad297a1950 py: Allow inline-assembler emitter to be generic.
This patch refactors some code so that it is easier to integrate new
inline assemblers for different architectures other than ARM Thumb.

Damien George 45a6156dfd esp8266: Enable native emitter for Xtensa arch.
This patch allows esp8266 to use @micropython.native and
@micropython.viper function decorators.  By default the executable machine
code is written to the space at the end of the iram1 region.  The user can
call esp.set_native_code_location() to make the code go to flash instead.

Damien George 8e5aced1fd py: Integrate Xtensa assembler into native emitter.
The config option MICROPY_EMIT_XTENSA can now be enabled to target the
Xtensa architecture with @micropython.native and @micropython.viper
decorators.
