(The "libc" part doesn't > matter.) Technically, IIRC llvm may make different decisions on libcall optimizations based on the libc part of the target triple. For instance, is bcmp defined in that libc or not? That's why we specify -gnu or -musl (I forgot we did that for hexagon) explicitly rather than leave that part of the triple blank. Minutia that doesn't need to be in this commit message, but now it's explicitly documented on LKML and linkable-to. > > Signed-off-by: WANG Xuerui <git@xxxxxxxxxx> Thanks for the patch!
