re PR target/88838 ([SVE] Use 32-bit WHILELO in LP64 mode)
gcc/ChangeLog:
2019-06-13 Kugan Vivekanandarajah <kugan.vivekanandarajah@linaro.org>
PR target/88838
* tree-vect-loop-manip.c (vect_set_loop_masks_directly): If the
compare_type is not with Pmode size, we will create an IV with
Pmode size with truncated use (i.e. converted to the correct type).
* tree-vect-loop.c (vect_verify_full_masking): Find IV type.
(vect_iv_limit_for_full_masking): New. Factored out of
vect_set_loop_condition_masked.
* tree-vectorizer.h (LOOP_VINFO_MASK_IV_TYPE): New.
(vect_iv_limit_for_full_masking): Declare.

* gcc.target/aarch64/pr88838.c: New test.
* gcc.target/aarch64/sve/while_1.c: Adjust.
