[PATCH] Fix bug in vect dumping code causing infinite loop
This patch fixes a bug in the dumping code, whereby an inner loop index variable was the same as the outer loop index variable, and the redef caused an infinite loop. Bootstrapped and tested on x86_64-unknown-linux-gnu. Ok for trunk? 2014-02-03 Teresa Johnson tejohn...@google.com * tree-vect-slp.c (vect_supported_load_permutation_p): Avoid redef of outer loop index variable.
