This patch adds CFI instructions in the function epilogue. Before patch: addi sp, s0, -32 ld ra, 24(sp) # 8-byte Folded Reload ld s0, 16(sp) # 8-byte Folded Reload ld s1, 8(sp) # 8-byte Folded Reload addi sp, sp, 32 ret After patch: addi sp, s0, -32 .cfi_def_cfa sp, 32 ld ra, 24(sp) # 8-byte Folded Reload ld s0, 16(sp) # 8-byte Folded Reload ld s1, 8(sp) # 8-byte Folded Reload .cfi_restore ra .cfi_restore s0 .cfi_restore s1 addi sp, sp, 32 .cfi_def_cfa_offset 0 ret This functionality is already present in `riscv-gcc`, but it’s not in `clang` and this slightly impairs the `lldb` debugging experience, e.g. backtrace.
