2015-04-16py: Overhaul and simplify printf/pfenv mechanism.Damien George
Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
2015-03-14py: In pfenv_vprintf, adjust type from mp_uint_t to unsigned int.Damien George
2015-01-20py, unix: Allow to compile with -Wunused-parameter.Damien George
See issue #699.
2015-01-12py: Can compile with -Wmissing-declarations and -Wmissing-prototypes.Damien George
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-12-10py: Remove static from definition of pfenv_printf.Damien George
It's used by stmhal, but not unix.
2014-12-10py: Make functions static where appropriate.Damien George
2014-11-27pfenv_printf: Properly implement %p format specifier.Paul Sokolovsky
Previously, it truncated pointer value to 32 bits on 64-bit systems.
2014-07-19py: Make print() accept "file" argument, and actually print to stream.Paul Sokolovsky
And not system printf(), like it was before. For this, move pfenv_printf() from stmhal port to py/.
