[SystemZ] Add CodeGen test cases This adds all CodeGen tests for the SystemZ target. This version of the patch incorporates feedback from a review by Sean Silva. Thanks to all reviewers! Patch by Richard Sandiford. llvm-svn: 181204
2013-05-07 00:17:29 +08:00
; Test the "S" asm constraint, which accepts addresses that have a base
; and a 20-bit displacement.
;
Use the integrated assembler as default on SystemZ This was already done in clang, this commit now uses the integrated assembler as default when using LLVM tools directly. A number of test cases deliberately using an invalid instruction in inline asm now have to use -no-integrated-as. llvm-svn: 225820

[SystemZ] Enable long displacement constraints for inline ASM operands This enables use of the 'S' constraint for inline ASM operands on SystemZ, which allows for a memory reference with a signed 20-bit immediate displacement. This patch includes corresponding documentation and test case updates. I've changed the 'T' constraint to match the new behavior for 'S', as 'T' also uses a long displacement (though index constraints are still not implemented). I also changed 'm' to match the behavior for 'S' as this will allow for a wider range of displacements for 'm', though correct me if that's not the right decision.

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.
