The (very old) regression in 10700 was introduced with this patch:

Sat Nov 27 08:38:26 1999  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

        * fold-const.c (negate_expr, associate_trees, extract_muldiv): New.
        (split_tree): Completely rework to make more general.
       (make_range, fold): Call negate_expr.
        (fold, case NEGATE_EXPR): Simplify -(a-b) is -ffast-math.
        (fold, associate): Call new split_tree and associate_trees.
        (fold, case MULT_EXPR, case *_{DIV,MOD}_EXPR): Call extract_muldiv.

The test case used an alpha-linux cross cc1 on i686-pc-linux-gnu with
the minimized test case from comment #1 in the PR, compiled with               
"-O3 -funroll-all-loops -fomit-frame-pointer -finline-functions".
