Use fixed variables for things that can't change, instead of variables
like SRCLIBDIR that was causing a shell call for every single use.
Use less functions in general and less shell expansions.
Use builtin functions like $(realpath blah) instead of $(shell
pwd)/blah In particular, this was important for me trying to build on
windows with git-shell. This should help a lot on smaller build
machines, but doesn't make a huge difference on my own.
Remove redundant clean print messages. These also cause more needless
shell expansions.
Create lm4f code infrastructure from the lm3s infrastructure.
As far as the interrupt table is concerned, don't create an irq.yaml. Just
include the LM3S nvic.h. The LM3S vector table seems to be compatible with the
LM4F

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
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
New doc directory with config files and generated html, LaTeX/pdf.
Makefile provided for autogeneration and explanatory README.
The project structure is hostile to doxygen, which can't cope with functions
of the same name. Doxygen is run for each family separately, and separately
for LaTeX generation. Customized layout files sort of "integrate" HTML, and
separate pdfs are generated for each family. Not ideal but seems the best
solution until doxygen changes, if at all.
- The library files are now being built into the lib subdirectory of the
source.
- The linker files for each library are being copied into the lib source
subdirectory.
Motivation: The relative locations of files in the source directory after make
are now the same as after make install now. This makes it easier to
reuse examples with their makefiles outside of the libopencm3
sourcecode directory.
includes minor refactoring in example code and modification of how the
generic and the tinygecko specific vector.h go together (bringing it in
line with stm32/f1's memorymap.h)
All #includes now explicitly use the "<libopencm3/stm32/rcc.h>" format.
If you want to get rid of the "libopencm3" prefix in your local project you
can add a respective -I entry in your Makefile (not recommended though).
All .ld files and .a libs are installed in $(TOOLCHAIN_DIR)/lib
directly (as before), but are now renamed to avoid potential
conflicts now or in the future. Examples:
libopencm3_lpc13xx.a
libopencm3_lpc13xx.ld
libopencm3_stm32.a
libopencm3_stm32.ld
