CRT functions don't get inlined anymore

[fwsGonzo]

After a certain change CRT functions stopped getting inlined. What happened?

$ riscv64-unknown-elf-objdump -drl level1.elf | grep memcpy | grep jal | wc -l
136

This was not the case when I implemented this feature.

With some experimentation, basic heap allocations are now inlined again. Still missing memory- and string- operations.
