Is the intended behavior of the "weak" version that the compiler can
increase or decrease it based on command line options etc., or that it
must unroll at least N times but with command line options etc. it could
be something higher than that?
Perhaps
#pragma GCC unroll 16
vs.
#pragma GCC unroll >= 16
or
#pragma GCC unroll 16+
?
As for keywords, I was worried about macros, but seems GCC unroll pragma
doesn't have macro expansion in the name nor arguments part, so when one
wants to macro expand the count, one needs to use _Pragma and create the
right expression as string literal.
