Remove unnecessary temporary in tree-if-conv.c
The call to ifc_temp_var in predicate_mem_writes become redundant in r230099. Before that point the mask was calculated using fold_build_*s, but now it's calculated by gimple_build and so is already a valid gimple value. As it stands, the call forces an SSA_NAME-to-SSA_NAME copy to be created, whereas SLP expects that such redundant copies have already been eliminated. 2018-01-13 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-if-conv.c (predicate_mem_writes): Remove redundant call to ifc_temp_var. From-SVN: r256638
