ARM: Fast-isel register class constrain for extends. Properly constrain the operand register class for instructions used in [sz]ext expansion. Update more tests to use the verifier now that we're getting the register classes correct. rdar://12594152 llvm-svn: 188594

Fix ARM FastISel tests, as a first step to enabling ARM FastISel ARM FastISel is currently only enabled for iOS non-Thumb1, and I'm working on enabling it for other targets. As a first step I've fixed some of the tests. Changes to ARM FastISel tests: - Different triples don't generate the same relocations (especially movw/movt versus constant pool loads). Use a regex to allow either. - Mangling is different. Use a regex to allow either. - The reserved registers are sometimes different, so registers get allocated in a different order. Capture the names only where this occurs. - Add -verify-machineinstrs to some tests where it works. It doesn't work everywhere it should yet. - Add -fast-isel-abort to many tests that didn't have it before. - Split out the VarArg test from fast-isel-call.ll into its own test. This simplifies test setup because of --check-prefix. Patch by JF Bastien llvm-svn: 181801

; Note that some of these tests assume that relocations are either
; movw/movt or constant pool loads. Different platforms will select

Add support for passing i1, i8, and i16 call parameters. Also, be sure to zero-extend the constant integer encoding. Test case provides testing for both call parameters and materialization of i1, i8, and i16 types. llvm-svn: 143821

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. llvm-svn: 183551

[arm-fast-isel] After promoting a function parameter be sure to update the argument value type. Otherwise, the sign/zero-extend has no effect on arguments passed via the stack (i.e., undefined high-order bits). rdar://10515467 llvm-svn: 145701

DebugInfo: Don't lose unreferenced non-trivial by-value parameters A FastISel optimization was causing us to emit no information for such parameters & when they go missing we end up emitting a different function type. By avoiding that shortcut we not only get types correct (very important) but also location information (handy) - even if it's only live at the start of a function & may be clobbered later.

Fix ARM FastISel tests, as a first step to enabling ARM FastISel ARM FastISel is currently only enabled for iOS non-Thumb1, and I'm working on enabling it for other targets. As a first step I've fixed some of the tests. Changes to ARM FastISel tests: - Different triples don't generate the same relocations (especially movw/movt versus constant pool loads). Use a regex to allow either. - Mangling is different. Use a regex to allow either. - The reserved registers are sometimes different, so registers get allocated in a different order. Capture the names only where this occurs. - Add -verify-machineinstrs to some tests where it works. It doesn't work everywhere it should yet. - Add -fast-isel-abort to many tests that didn't have it before. - Split out the VarArg test from fast-isel-call.ll into its own test. This simplifies test setup because of --check-prefix. Patch by JF Bastien llvm-svn: 181801

[arm-fast-isel] After promoting a function parameter be sure to update the argument value type. Otherwise, the sign/zero-extend has no effect on arguments passed via the stack (i.e., undefined high-order bits). rdar://10515467 llvm-svn: 145701
