[PATCH] D69897: Add #pragma clang loop aligned
m-happy created this revision.
m-happy added reviewers: hfinkel, DTharun, rscottmanley, Meinersbur.
m-happy added a project: clang.
Herald added subscribers: cfe-commits, zzheng.
This patch adds functionality '#pragma clang loop aligned'. The load/store
access in for loop following the '#pragma clang loop aligned' uses 32 bit for
align access.
#pragma clang loop aligned(enable)

[PATCH] D69897: Add #pragma clang loop vectorize_assume_alignment(n)
m-happy updated this revision to Diff 229190.
m-happy added a comment.
Updated the syntax as suggested by Michael Kruse, and added functionality to
specify the number used for alignment instead of just using 32bits.
