[PATCH] D126192: [Driver] Improve linking options for target AVR

[Haowei Wu via Phabricator via cfe-commits]

haowei added a comment.

Emmm, I applied your latest patch on top of main(6e02e27536b9de25a651cfc9c2966ce471169355 <https://reviews.llvm.org/rG6e02e27536b9de25a651cfc9c2966ce471169355>) but I still get a test failure on `Clang :: Driver/avr-toolchain.c`.

`Clang :: Driver/avr-ld.c` no longer fail.
Error message:

  FAIL: Clang :: Driver/avr-toolchain.c (7349 of 16540)
