Oh ah, is this so? If so that's a problem for Billa because he's trying to rebuild Fedora for the SHAKTI chip that lacks compressed instructions. But I had a look through all the RISC-V asm files in current glibc and I can't see any compressed instructions there, nor any directives to turn on the rvc option. $ egrep -i '(\bc\.|rvc)' `find sysdeps/riscv/ sysdeps/unix/sysv/linux/riscv/ -name '*.S' ` Do you know why glibc wouldn't understand the C extension?
