MATCH: Factor out code that for min max detection with constants
This factors out some of the code from the min/max detection
from match.pd into a function so it can be reused in other
places. This is mainly used to detect the conversions
of >= to > which causes the integer values to be changed by
one.
Changes since v1:
* factor out the checks for INTEGER_CSTs so it is more obvious.
OK? Bootstrapped and tested on x86_64-linux-gnu.
gcc/ChangeLog:
* match.pd: Factor out the deciding the min/max from
the "(cond (cmp (convert1? x) c1) (convert2? x) c2)"
pattern to ...
* fold-const.cc (minmax_from_comparison): this new function.
* fold-const.h (minmax_from_comparison): New prototype.
