test: modernise ARM CodeGen tests Replace the use of grep with FileCheck. Tidy up some of the tests. A few of the tests have been left as weak as previously, though some have been made more stringent. llvm-svn: 290616

For PR761: Remove "target endian/pointersize" or add "target datalayout" to make the test parse properly or set the datalayout because defaults changes. For PR645: Make global names use the @ prefix. For llvm-upgrade changes: Fix test cases or completely remove use of llvm-upgrade for test cases that cannot survive the new renaming or upgrade capabilities. llvm-svn: 33533

[ARM] Fix test CodeGen/ARM/fpcmp_ueq.ll broken by rL290616 Commit rL290616 (https://reviews.llvm.org/rL290616) changed a checking command for the triple arm-apple-darwin in LLVM::CodeGen/ARM/fpcmp_ueq.ll. As a result of the changes the test could fail for the valid generated code. These changes fixes the test to check only instructions we would expect.

[ARM] Use VCMP, not VCMPE, for floating point equality comparisons When generating a floating point comparison we currently unconditionally generate VCMPE. This has the sideeffect of setting the cumulative Invalid bit in FPSCR if any of the operands are QNaN. It is expected that use of a relational predicate on a QNaN value should raise Invalid. Quoting from the C standard: The relational and equality operators support the usual mathematical relationships between numeric values. For any ordered pair of numeric values exactly one of relationships the less, greater, equal and is true. Relational operators may raise the floating-point exception when argument values are NaNs. The standard doesn't explicitly state the expectation for equality operators, but the implication and obvious expectation is that equality operators should not raise Invalid on a QNaN input, as those predicates are wholly defined on unordered inputs (to return not equal). Therefore, add a new operand to ARMISD::FPCMP and FPCMPZ indicating if QNaN should raise Invalid, and pipe that through to TableGen. llvm-svn: 294945
