ARM: fixup more tests to specify the target more explicitly This changes the tests that were targeting ARM EABI to explicitly specify the environment rather than relying on the default. This breaks with the new Windows on ARM support when running the tests on Windows where the default environment is no longer EABI. Take the opportunity to avoid a pointless redirect (helps when trying to debug with providing a command line invocation which can be copy and pasted) and removing a few greps in favour of FileCheck. llvm-svn: 205541

ARM: Teach assembler to enforce constraint for Thumb2 LDRD (literal/immediate) destination register operands. LDRD<c> <Rt>, <Rt2>, <label> LDRD<c> <Rt>, <Rt2>, [<Rn>{, #+/-<imm>}] LDRD<c> <Rt>, <Rt2>, [<Rn>], #+/-<imm> LDRD<c> <Rt>, <Rt2>, [<Rn>, #+/-<imm>]! As specified in A8.8.72/A8.8.73 in the ARM ARM, the T1 encoding has a constraint which enforces that Rt != Rt2. If this constraint is not met the result of executing the instruction will be unpredictable. Fixes rdar://14479780. llvm-svn: 191504
