sign_extend_inreg operations. Though ComputeNumSignBits is still rudimentary, this is enough to compile this: short test(short X, short x) { int Y = X+x; return (Y >> 1); } short test2(short X, short x) { int Y = (short)(X+x); return Y >> 1; } into: _test: add r2, r3, r4 srawi r3, r2, 1 blr _test2: add r2, r3, r4 extsh r2, r2 srawi r3, r2, 1 blr instead of: _test: add r2, r3, r4 srawi r2, r2, 1 extsh r3, r2 blr _test2: add r2, r3, r4 extsh r2, r2 srawi r2, r2, 1 extsh r3, r2 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28146 91177308-0d34-0410-b5e6-96231b3b80d8 |
