Thank you for the .ll files!
the -4.ll file you sent me contains:
define dso_local i64 @"?test__shiftleft128@@YA_K_K0E@Z"(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
}
On my local system, I get
; Function Attrs: minsize norecurse nounwind optsize readnone
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
}
That's identical except for the order of the instructions (which in turn
changes some % numbers).
That's surprising to me; I thought LLVM IR is deterministic (and if it
wasn't, many other tests wouldn't work either).
