I have seeing the below error with lld ( trunk and 16.0.0 release )on riscv in combination with GAS from binutils 2.41 ( upcoming ) release built objects e.g. from glibc .a files.

riscv64-yoe-linux-ld.lld: error: TOPDIR/build/tmp/work/riscv64-yoe-linux/libcap-ng/0.8.3-r0/recipe-sysroot/usr/lib/libc_nonshared.a(pthread_atfork.oS):(.debug_loclists+0xd): unknown relocation (60) against symbol .LVL0

riscv64-yoe-linux-ld.lld: error: TOPDIR/build/tmp/work/riscv64-yoe-linux/libcap-ng/0.8.3-r0/recipe-sysroot/usr/lib/libc_nonshared.a(pthread_atfork.oS):(.debug_loclists+0xd): unknown relocation (61) against symbol .Ltext0

These are R_RISCV_SET_ULEB128 and R_RISCV_SUB_ULEB128 relocations.

Thanks for reporting - we were aware of needing this to land but really should have made an issue to track that.

The first step is my assembler change: https://reviews.llvm.org/D157657
Then we need to change lld.
