Coverage analysis and profiling with Arm Toolchain for Embedded (ATfE): missing libclang_rt.profile.a

Hi,

I'm currently building an application for ARM Cortex-M33 with both the ARM GNU Toolchain and ATfE.  When using the GNU toolchain, I can build with --coverage and then run the tests in an emulator (QEMU on MPS2-AN505) with semihosting and get the coverage data recorded.

However, with ATfE, libclang_rt.profile.a is not provided and so it's not possible to use the profiling options e.g. -fprofile-instr-generate -fcoverage-mapping.  Ideally, I'd quite like to use the LLVM native coverage profiling with -fprofile-instr-generate -fcoverage-mapping.

So this post is really a query to ask why libclang_rt.profile.a is missing, and if it would be possible to add it in a future release?  Also, is it something that can be enabled in the current release if I rebuild it myself?

Thanks,

Roger
