# REQUIRES: x86
## Test R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX/R_X86_64_CODE_4_GOTPCRELX GOT optimization.

# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t.o

## --no-relax disables GOT optimization.

## In our implementation, .got is retained even if all GOT-generating relocations are optimized.
