aaron.ballman added a comment. I'm not certain if it will be possible to devise test cases for the two diagnostics I pointed out or not, but otherwise, this LGTM as far as the implementation goes. I don't know enough about AVR to sign off on whether the patch logic is correct or not. ===

[PATCH] D54334: [AVR] Automatically link CRT and libgcc from the system avr-gcc

dylanmckay added a comment. I'd like feedback on the new AVR-specific warnings, and the new warning group. I have not added a warning or error to clang before, but this seems consistent with how the other targets implement it. Repository: rC Clang https://reviews.llvm.org/D54334

[PATCH] D54334: [AVR] Automatically link CRT and libgcc from the system avr-gcc

dylanmckay created this revision. dylanmckay added reviewers: aaron.ballman, kparzysz, asb, hfinkel. This patch modifies the AVR toolchain so that if avr-gcc and avr-libc are detected during compilation, the CRT, libgcc, libm, and libc anre linked. This matches avr-gcc's default behaviour, and th
