re PR middle-end/79673 (GIMPLE verification fails when compiling code with __seg_gs)
2017-02-22 Richard Biener <rguenther@suse.de>
PR tree-optimization/79673
* tree-ssa-pre.c (compute_avail): Use wide_int_to_tree to
convert the [TARGET_]MEM_REF offset INTEGER_CST, scrapping off
irrelevant address-space qualifiers and avoiding a
ADDR_SPACE_CONVERT_EXPR from fold_convert.
* gcc.target/i386/pr79673.c: New testcase.
