--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> --- ;; MEM <unsigned char[128]> [(void *)&reversal] = *.LC1; (insn 35 34 36 (set (reg:DI 667) (symbol_ref/f:DI ("*.LC11") [flags 0x2] <var_decl 0x7f185eff9990 *.LC11>)) "/var/tmp/portage/dev-libs/libgcrypt-1.11.0-r1/work/libgcrypt-1.11.0/cipher/mceliece6688128f.c":2641:22 -1 (nil)) ... It is hard to debug since it depends on not doing -save-temps ... But LC11 is not emitted in the object file in the end.
