This revision is now accepted and ready to land.

Looks good to me, thanks for the patch @benshi001

NOTE: It looks like you will need to rebase this one prior to merge.

2020-10-31 Thread Ayke via Phabricator via cfe-commits 
aykevl added a comment.

I haven't verified this all but this looks reasonable to me, at least until a 
better way is figured out to store MCU specific information in the compiler.

The tests may be a little bit excessive though, they all seem to be testing the 
same thing.

[PATCH] D88410: [clang][AVR] Improve avr-ld command line options

2020-09-28 Thread Ben Shi via Phabricator via cfe-commits 
benshi001 added a comment.

For some devices, the library sub path "-L" and family name "-m" are not always 
equal.
-L/usr/lib/avr/lib/XXX" "-L/usr/lib/gcc/avr/5.4.0/XXX" "-mYYY"

XXX and YYY do not always equal to each other. But current 
clang/lib/Driver/ToolChains/AVR.cpp assumes they equal.

For example, "./bin/clang  -O2 -Wall b.c --target=avr -mmcu=atmega2313" needs 
the following avr-ld options
"/usr/bin/avr-ld" *** "-L/usr/lib/avr/lib/avr25/tiny-stack" 
"-L/usr/lib/gcc/avr/5.4.0/avr25/tiny-stack" "-mavr25"

Here XXX=avr25/tiny-stack but YYY = avr25
