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

Open JoshuaYonathan opened this issue 8 months ago • 1 comments

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 me the output I expect, but wouldn't it be the correct behavior to select the non-exn_rtti libs when invoking clang and not clang++?
