openmano-mpy/ports/minimal/Makefile, branch master MicroPython source and hardware configuration for OpenMano minimal: Make build more flexible and work as 64-bit build. 2020-06-02T05:43:44+00:00 Damien George 2020-05-29T21:35:19+00:00 8e591d412a9922d71629f4fea74954d547f0c955 Changes are: - string0 is no longer built when building for host as the target, because it'll be provided by the system libc and may in some cases clash with the system one (eg on OSX). - mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support both 32-bit and 64-bit builds. - Configuration values which are the default in py/mpconfig.h are removed from mpconfigport.h to make the configuration a bit more minimal, eg as a better starting point for new ports. 
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.
all: Enable extra conversion warnings where applicable. 2020-04-18T12:42:28+00:00 stijn 2020-04-09T11:59:11+00:00 30840ebc9925bb8ef025dbc2d5982b1bfeb75f1b Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out implicit floating point conversions, and add extra Travis builds using MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found previously. For the unix port -Wsign-comparison is added as well but only there since only clang supports this but gcc doesn't.

ports: Allow overriding CROSS_COMPILE in a custom makefile. 2019-12-27T12:53:16+00:00 David Lechner 2019-12-21T20:22:26+00:00 e79424d672919bfc59862d14f2d9e78e43e8582e Many ports already allow overriding CROSS_COMPILE. This modifies the remaining ports to allow it as well.

bare-arm, minimal: Set CSUPEROPT=-Os to get minimal firmware size. 2019-09-17T01:43:52+00:00 Damien George 2019-09-12T12:14:51+00:00 b45f9de8096f37a5f588f833e6b6a00b59e67e3f This option affects py/vm.c and py/gc.c and using -Os gets them compiling a bit smaller, and small firmware is the aim of these two ports. Also, having these files compiled with -Os on these ports, and -O3 as the default on other ports, gives a better understanding of code-size changes when making changes to these files.

minimal: Use soft float for CROSS=1 Cortex-M4 target. 2019-07-01T12:48:05+00:00 Damien George 2019-07-01T12:41:47+00:00 999733b1fb08fb07a31846115998dbf43a913327 When compiled with hard float the system should enable FP access when it starts or else FP instructions lead to a fault. But this minimal port does not enable (or use) FP and so, to keep it minimal, switch to use soft floating point. (This became an issue due to the recent commit 34c04d2319cdfae01ed7bf7f9e341d69b86d751a which saves/restores FP registers in the NLR state.)

This speeds up the build by about 10% when building with a single core.
