Same thing for me with our downstream build bots.
When we compile clang with gcc 7.4 and then run the testcase I get this
output
define dso_local i64 @test__shiftleft128(i64 %l, i64 %h, i8 %d)
local_unnamed_addr #0 {
entry:
%0 = zext i64 %l to i128
%1 = zext i64 %h to i128
%2 = shl nuw i128 %1, 64
%3 = or i128 %2, %0
%4 = and i8 %d, 63
%5 = zext i8 %4 to i128
%6 = shl i128 %3, %5
%7 = lshr i128 %6, 64
%8 = trunc i128 %7 to i64
ret i64 %8
}
and when I compile clang with clang 3.6 and run the test I get this:
define dso_local i64 @test__shiftleft128(i64 %l, i64 %h, i8 %d)
local_unnamed_addr #0 {
entry:
%0 = zext i64 %h to i128
%1 = shl nuw i128 %0, 64
%2 = zext i64 %l to i128
%3 = or i128 %1, %2
%4 = and i8 %d, 63
%5 = zext i8 %4 to i128
%6 = shl i128 %3, %5
%7 = lshr i128 %6, 64
%8 = trunc i128 %7 to i64
ret i64 %8
}
