../../../../gcc/gcc/lra-eliminations.c: In function ‘void init_elim_table()’:
../../../../gcc/gcc/lra-eliminations.c:1162:8: warning: unused variable
‘value_p’ [-Wunused-variable]
bool value_p;
^
This is because we don't eliminate any registers (beyond GCC's
internal default). Fixed by moving this variable into the #ifdef block
to which it belongs.
