Considering the number of project files spread in different locations
when developing an Arduino project, proper use of tags can be difficult;
resolving beyond local functions.
I've added automatic generation of a tags file, which includes:
* Standard ctags source in project dir (.c, .cpp, .h)
* Arduino source in project dir (.ide, .pde)
* Arduino core based on detected project core from Arduino install.
* Included Arduino libraries from user library folder.
As a Vim user I find this hugely useful and think it would be a useful
addtion for others. Target has been added as `make tags`.
doesn't support LTO or plugins. Fixes Issue #456
So essentially LTO support will only be enabled with avr-gcc 4.9.2 which comes with 1.6.10 or later
and Debian, Ubuntu etc; not 4.8.1 which comes with IDE 1.6.9 and a few earlier versions.
Tested with:
* 1.6.8 (avr-gcc 4.8.1 which doesn't support LTO so uses avr-ar and doesn't set LTO flags)
* 1.6.12 (avr-gcc 4.9.2 which supports LTO so uses avr-gcc-ar and sets LTO flags)
* 1.0.5 with Debian avr-gcc 4.9.2 (supports LTO so uses avr-gcc-ar and sets LTO flags)
upstream (without it compilation seems to fail on OSX). Updated docs.
Also made ARDUINO_LIB_PATH overloadable (as implied by arduino-mk-vars.md) although this is a
pretty niche use-case.
$ARCHITECTURE is probably safe as that's usually called $ARCH.
Fixes issue #386.
Need to decide if this is going to upset too many user's who have already
started using $VENDOR - and who uses tcsh? ;-)
We currently pass the -D (do not erase) option to avrdude
unconditionally in order to work around an Arduino Mega bootloader bug.
However, this has the side-effect of breaking the ispload target for all
non-XMEGA chips, since a write operation on these chips essentially ANDs
the new program with the existing memory contents. If the memory is not
first erased to contain only 0xff, the resulting image is garbage. This
patch makes it so we pass -D when we're using the Arduino bootloader but
don't pass it when we're using ISP directly.
- Add support for 1.5.x library layout.
(https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification)
- Allow using Arduino 1.5.x platform specific system libraries.
Arduino 1.5.x has additional directories for platform (vendor/architecture)
specific libraries - look there when searching for libraries.
