all: Update Makefiles and others to build with new ports/ dir layout. Also renames "stmhal" to "stm32" in documentation and everywhere else.

Add 'bare-arm' port: the bare minimum to get it running on an ARM MCU.

# qstr definitions (must come before including py.mk)
QSTR_DEFS = qstrdefsport.h
ports: Enable error text compression for various ports, but not all. Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32, esp8266, cc3200, teensy, qemu-arm, nrf. Not enabled on others to be able to test the code when the feature is disabled (the default case).

ports: Allow overriding CROSS_COMPILE in a custom makefile. Many ports already allow overriding CROSS_COMPILE. This modifies the remaining ports to allow it as well.

all: Make netutils.h available to all ports by default. Generally, ports should inherit INC from py.mk, append to it, not overwrite it. TODO: Likely should do the same for other vars too.
2015-10-19 16:22:16 +01:00
INC += -I.
all: Make use of $(TOP) variable in Makefiles, instead of "..". $(TOP) is defined in py/mkenv.mk and should be used to refer to the top level of this repository.

INC += -I$(TOP)
build: Simplify build directory layout by putting all headers in genhdr. Any generated headers go in $(BUILD)/genhdr/, and are #included as 'genhdr/xxx.h'.
2014-04-17 18:03:27 +01:00
INC += -I$(BUILD)
build directory can now be renamed The autogenerated header files have been moved about, and an extra include dir has been added, which means you can give a custom BUILD=newbuilddir option to make, and everything "just works" Also tidied up the way the different Makefiles build their include- directory flags

bare-arm, minimal: Set CSUPEROPT=-Os to get minimal firmware size. 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.

ports/{bare-arm,minimal}/Makefile: Only build with core source files. These ports don't need anything from extmod so don't include those files at all in the build. This speeds up the build by about 10% when building with a single core.

Makefiles: Remove duplicate object files when linking. Scenario: module1 depends on some common file from lib/, so specifies it in its SRC_MOD, and the same situation with module2, then common file from lib/ eventually ends up listed twice in $(OBJ), which leads to link errors. Make is equipped to deal with such situation easily, quoting the manual: "The value of $^ omits duplicate prerequisites, while $+ retains them and preserves their order." So, just use $^ consistently in all link targets.
