Switch a bunch of Linker tests from using elaborate echo productions to just provide and reference separate input files from an Inputs subdirectory. This pattern works very well in the Clang tree and is easier to understand in my opinion. It also has fewer limitations and will remove one particularly annoying use of TCL-style {} quoting from the testsuite. Also teach the LLVM lit configuration to avoid recursing into 'Inputs' subdirectories. This wasn't required for the previous 'Inputs' subdirectories used due to fortuitous suffix patterns. This is the first step to completely removing support for TCL-style tests. llvm-svn: 159520 2012-07-02 12:18:06 +02:00			`%foo = type { [8 x i8] }`

Allow alias to point to an arbitrary ConstantExpr. This patch changes GlobalAlias to point to an arbitrary ConstantExpr and it is up to MC (or the system assembler) to decide if that expression is valid or not. This reduces our ability to diagnose invalid uses and how early we can spot them, but it also lets us do things like @test5 = alias inttoptr(i32 sub (i32 ptrtoint (i32* @test2 to i32), i32 ptrtoint (i32* @bar to i32)) to i32) An important implication of this patch is that the notion of aliased global doesn't exist any more. The alias has to encode the information needed to access it in its metadata (linkage, visibility, type, etc). Another consequence to notice is that getSection has to return a "const char ". It could return a NullTerminatedStringRef if there was such a thing, but when that was proposed the decision was to just uses "const char*" for that. llvm-svn: 210062 2014-06-03 04:41:57 +02:00			`@zed = alias bitcast (void (%bar) @xyz to void (%foo))`
