;; Date: May 27, 2003.
|
|
;; From: Variant of 2003-05-27-usefsubasbool.ll
|

;;
|
|
;; Error: llc fails to save a boolean value in a register (and later uses an
|
|
;; invalid register <NULL VALUE> in a BRNZ) for a boolean value
|
|
;; used only by branches but in a different basic block.
|
|
;;
|
|
;; Cause: In SparcInstrSelection.cpp, for SetCC, when a result of setCC
|
|
;; is used only for branches, it is not saved into an int. register.
|
|
;; But if the boolean is used in a branch in a different basic block,
|
|
;; that branch uses a BRNZ inst. instead of a branch-on-CC.
