Subject: Initialize all fields in ABIArgInfo.
X-Git-Tag: llvmorg-11-init~8859
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e93aded7f02d661234ad81aac0785ccdef6a79dd;p=platform%2Fupstream%2Fllvm.git

Initialize all fields in ABIArgInfo.

Due to usage of an uninitialized fields, we end up with
a Conditional jump or move depends on uninitialised value

Fixes https://bugs.llvm.org/show_bug.cgi?id=40547
