The routines declared as
static bool
is_too_expensive (const char *pass)
in both cprop.c and gcse.c are identical except for two comment lines.
I'd like to modify is_too_expensive, which implied to me that there
should be only one copy of the routine.
Would it be reasonable to add an extern declaration of is_too_expensive
(with perhaps a more descriptive name) in gcse.h, remove the static
declaration from gcse.c, include gcse.h in cprop.c?
(I realize this is a very simple question for regular C programmers, but
I'm not a regular C programmer, sorry).
