The reason for this is that one instance # where this pattern appears in in the .eh_frame section (the CIE 'length' # field), and the .eh_frame section cannot be parsed by the linker unless the # fixup has been resolved to a concrete value instead of a relocation. .data lo: .word hi-lo .quad hi-lo # NORELAX-RELOC-NOT: R_RISCV_32 # NORELAX-RELOC-NOT: R_RISCV_64 # RELAX-RELOC-NOT: R_RISCV_32 # RELAX-RELOC-NOT: R_RISCV_64 hi:
