[Zephyr Project](https://github.com/zephyrproject-rtos/zephyr) is becoming more and more popular in the RTOS area. For ARM Cortex architecture, they have their own toolchain/SDK based on GCC. And the ARM maintained arm-none-eabi-gcc also...

Could you please include llvm-link, llc and opt?

12

Could you please include the above files via "clang-tools-extra"? Our build system relies on those to do link time optimization. Or are those steps completely outdated?

clang/clang++ multi-lib selection: prefer no rtti, no exceptions variant for clang

1

Hello, When I run the following command: `clang -print-multi-directory --target=arm-none-eabi -march=armv7e-m -mfloat-abi=hard -mfpu=fpv5-d16` I expect the output: `arm-none-eabi/armv7em_hard_fpv5_d16` However, I get the output: `arm-none-eabi/armv7em_hard_fpv5_d16_exn_rtti` Adding the `-fno-rtti -fno-exceptions` flags gets...

Adjust clang's multilib flags test to cope with missing variant

1

The clang driver's `print-multi-selection-flags.c` test uses a combination of command line options in one of its RUN lines for which we don't have a valid library variant available. Since the...
