Nate Begeman d2558e3e4a Teach the legalizer how to legalize FP_TO_UINT. ... Teach the legalizer to promote FP_TO_UINT to FP_TO_SINT if the wider FP_TO_UINT is also illegal. This allows us on PPC to codegen unsigned short foo(float a) { return a; } as: _foo: .LBB_foo_0: ; entry fctiwz f0, f1 stfd f0, -8(r1) lwz r2, -4(r1) rlwinm r3, r2, 0, 16, 31 blr instead of: _foo: .LBB_foo_0: ; entry fctiwz f0, f1 stfd f0, -8(r1) lwz r2, -4(r1) lis r3, ha16(.CPI_foo_0) lfs f0, lo16(.CPI_foo_0)(r3) fcmpu cr0, f1, f0 blt .LBB_foo_2 ; entry .LBB_foo_1: ; entry fsubs f0, f1, f0 fctiwz f0, f0 stfd f0, -16(r1) lwz r2, -12(r1) xoris r2, r2, 32768 .LBB_foo_2: ; entry rlwinm r3, r2, 0, 16, 31 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22785 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-14 01:20:53 +00:00
