Subject: [FastISel] Insert patchpoint instruction before the target generated call instruction.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=718bb71ade3a37552aa5f99a313d17554d4cda42;p=platform%2Fupstream%2Fllvm.git

[FastISel] Insert patchpoint instruction before the target generated call instruction.

The patchpoint instruction should have been inserted before the target
generated call instruction to be inside the ADJSTACKDOWN/ADJSTACKUP call
sequence window.
