This was an oversight of not knowing there are a few different integer divisions and how they will round. When `a < b` and for non-negative a and b, `a/b` will be 0 iff for truncate (TRUNC_DIV_EXPR), exact (EXACT_DIV_EXPR) and floor division (FLOOR_DIV_EXPR). Ceiling division (CEIL_DIV_EXPR) will be 1 for positive a and zero when a is 0. Rounding division (ROUND_DIV_EXPR) it is based on the how far a is from b. We can skip the ceiling division case since it is not used that much. And rounding division case is too hard to figure out here so that is skipped also. Bootstrapped and tested on x86_64-linux-gnu. PR tree-optimization/127092 gcc/ChangeLog: * range-op.cc (operator_div::op1_op2_relation_effect): Only handle TRUNC_DIV_EXPR, EXACT_DIV_EXPR and FLOOR_DIV_EXPR for the `a < b` case. gcc/testsuite/ChangeLog: * gfortran.dg/pr127092-1.f90: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
