re PR tree-optimization/77901 (ICE in tree-sse-reassoc,c:2881)
PR tree-optimization/77901
* tree-ssa-reassoc.c (optimize_range_tests_var_bound): Only optimize
if ranges[i].exp is SSA_NAME when looking for >= and only when
ranges[i].exp is NULL or SSA_NAME when looking for the other
comparison.
* gcc.c-torture/compile/pr77901.c: New test.
