Bug ID: 31600
Summary: Allow vector value types to use signext/zeroext
attributes
Product: new-bugs
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: llvm-...@redking.me.uk
CC: llvm-bugs@lists.llvm.org, spatel+l...@rotateright.com
Classification: Unclassified
As discussed on [Bug #28486], we don't currently support signext/zeroext
attributes on vector value types:
define <4 x i32> @boolext(<4 x i1> signext %a) {
%ext = sext <4 x i1> %a to <4 x i32>
ret <4 x i32> %ext
}
Doing so could help in a number of cases, for instance when passing around
mask/boolean vector data.
