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)
$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? ;-)
With this fix the `TARGET` variable is set correctly when the project directory
(or its path) contains spaces. So in this case:
/Users/Joe/Dropbox (Personal)/example project
`TARGET` will be set to `example_project` instead of `Dropbox example project`
(like it was before this fix).
Needed to fix the new wiring_pulse.S in IDE 1.6.5 which
also has a wiring_pulse.c source file.
Mostly rebased @peplin's PR #266, so should allow us
to support newer chipKIT builds too.
I found that the previous reset code did not work for Leonardo or Micro, nor did any reset code anywhere on the internet.
An examination of the Arduino IDE source code (and the JNI code behind its serial implementation) shows that it holds RTS high and DTR low when doing the 1200 baud open/close. And it turns out that's exactly what's needed!
For instance in the Sparkfun 1.6 core, we have:
promicro16.build.vid.0=0x1B4F
promicro16.build.vid.1=0x1B4F
promicro16.build.vid=0x1B4F
So we end up matching all 3 instead of just the last one.
Adding the = means we're looking for promicro16.build.vid= so
not catching the .0 or .1 version.
existing builds.
E.g. mega1280 and mega2560 previously *both* created a "build-mega" directory,
now they'll create build-mega-mega2560 and build-mega-mega1280
Only applies to 1.5+ of course, and only when BOARD_SUB is used. 1.0 will still
create build-mega2560 and build-mega1280 directories (just BOARD_TAG)
