JF Bastien 8fc760cbe8 ARM FastISel integer sext/zext improvements ... My recent ARM FastISel patch exposed this bug: http://llvm.org/bugs/show_bug.cgi?id=16178 The root cause is that it can't select integer sext/zext pre-ARMv6 and asserts out. The current integer sext/zext code doesn't handle other cases gracefully either, so this patch makes it handle all sext and zext from i1/i8/i16 to i8/i16/i32, with and without ARMv6, both in Thumb and ARM mode. This should fix the bug as well as make FastISel faster because it bails to SelectionDAG less often. See fastisel-ext.patch for this. fastisel-ext-tests.patch changes current tests to always use reg-imm AND for 8-bit zext instead of UXTB. This simplifies code since it is supported on ARMv4t and later, and at least on A15 both should perform exactly the same (both have exec 1 uop 1, type I). 2013-05-31-char-shift-crash.ll is a bitcode version of the above bug 16178 repro. fast-isel-ext.ll tests all sext/zext combinations that ARM FastISel should now handle. Note that my ARM FastISel enabling patch was reverted due to a separate failure when dealing with MCJIT, I'll fix this second failure and then turn FastISel on again for non-iOS ARM targets. I've tested "make check-all" on my x86 box, and "lnt test-suite" on A15 hardware. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183551 91177308-0d34-0410-b5e6-96231b3b80d8		2013-06-07 20:10:37 +00:00
