Change some ARM subtarget features to be single bit yes/no in order to sink them down to MC layer. Also fix tests. llvm-svn: 134590

Attempt again to fix buildbot failures: make expected output less specific and compile with -mtriple to specify *-apple-darwin targets. llvm-svn: 86081

Remove arm_apcscc from the test files. It is the default and doing this matches what llvm-gcc and clang now produce. llvm-svn: 106221

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.

This adds range checking for "ldr Rn, [pc, #imm]" Thumb instructions.

fix AsmPrinter::GetBlockAddressSymbol to always return a unique label instead of trying to form one based on the BB name (which causes collisions if the name is empty). This fixes PR6608 llvm-svn: 98495
