Bug ID: 52031
Summary: OrcJIT breaks call with <4 x i64> vector
Product: libraries
Version: 12.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: OrcJIT
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
On x86-64, lli -jit-kind=orc executes the following code incorrectly. The
return value from main should be 0. Instead, it returns 16. lli -jit-kind=mcjit
and llc produce the correct output.
define i32 @main() #0 {
br label %1
1: ; preds = %1, %0
%2 = phi i64 [ 0, %0 ], [ %6, %1 ]
%3 = phi <4 x i64> [ <i64 -16, i64 -16, i64 -16, i64 -16>, %0 ], [ %5, %1 ]
%4 = trunc <4 x i64> %3 to <4 x i32>
%5 = call <4 x i64> @new_function(<4 x i64> %3)
%6 = add i64 %2, 1
%7 = icmp eq i64 %6, 2
br i1 %7, label %8, label %1
8: ; preds = %1
%9 = extractelement <4 x i32> %4, i32 3
ret i32 %9
}
define <4 x i64> @new_function(<4 x i64> %0) unnamed_addr {
%2 = add <4 x i64> %0, <i64 16, i64 16, i64 16, i64 16>
ret <4 x i64> %2
}
attributes #0 = { "target-features"="+cx8,+fxsr,+mmx,+sse,+sse2,+x87" }
