You are probably referring to [1]? It looks OK, modulo: +DEF_TUNE (X86_TUNE_QIMODE_MATH, "qimode_math", ~(0U)) where parenthesis are not needed. Please resubmit the patch with a ChangeLog entry, as instructed in [2] [1] https://gcc.gnu.org/ml/gcc-patches/2016-08/msg02129.html [2] https://gcc.gnu.org/contribute.html#patches Uros. > On 8/31/16, Eric Gallager <eg...@gwmail.gwu.edu> wrote: >> In https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01526.html I tried >> enabling -Wnarrowing when building GCC and produced a log of the >> resulting (uniq-ed) warnings/errors.
