Where the library is installed has quite an affect on what -L and -I
flags are used. If you install into the toolchain, you don't want
to use them at all, but if you install out of tree (/opt/mycm3 for
example) you need to specify the -L and -I flags.
Update the documentation and the example makefiles to support this
You cannot issue make inside a for loop if you want to let it run in
parallel. Performance increases seen:
10:03 < zyp> I tested make all -j8 without your change, it takes 8.7s
10:03 < zyp> so on my cpu, your change gives >2x speedup
My own cpu gives more modest speed increases, of only about 20%.
this adds support for energy micro's efm32 tiny gecko, gecko, leopard gecko and
giant gecko series.
also, the experimental libopencmsis is included in this branch, as it is
required for full operation of the free energymicro standard library
this merges common c and header files of different architectures, adds a
dispatch mechanism and yaml descriptions of interrupt handlers from which the
whole interrupt table setup c code is generated.
as header file generation is not directly controlled by make (which, by
the way, makes the generatedheaders target phony), the script has to
take care of not needlessly generating files itself lest to have make
rebuild everything everytime
the LM3S irq list was previously unused as it was missing in the
dispatch files; now it got added. (before HEAD^, it wouldn't have made
any difference because the discriminating constant wasn't defined
anyway)
also, this enhances the warning messages
previously, only stm32 chips passed the information about which chip to
build on into the compiler. this information is essential to dispatch,
thus defining LPC13XX, LPC17XX, LPC43XX and LM3S in analogy to
STM32F1..4.
vector.o, nvic.o, scb.o and assert.o are available on every platform,
but at least some of them differ between the implementations. they
already got built explicityly on some platforms; now adding them to the
common Makefile.include.
the only change this results in in the example binaries is in the
hackrf-jellybean/systick example, where the the check in
systick_set_clocksource for overflowing from the stm32 area gets used.
these register definitions are common to all cortex mcus. some of the
registers might not be implemented everywhere (especially the floating
point registers), but defining them does no harm.
this modification does not result in any changes in the example
binaries.
