From: Dan Gohman Date: Mon, 23 Nov 2009 23:20:51 +0000 (+0000) Subject: Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=735afe14eea8049bf69210ce8a3512e391fc643f;p=oota-llvm.git Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used. Note that "hasDotLocAndDotFile"-style debug info was already broken; people wanting this functionality should implement it in the AsmPrinter/DwarfWriter code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89711 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/include/llvm/CodeGen/SelectionDAGNodes.h b/include/llvm/CodeGen/SelectionDAGNodes.h index aa60ef2660d..950fd322da2 100644 --- a/include/llvm/CodeGen/SelectionDAGNodes.h +++ b/include/llvm/CodeGen/SelectionDAGNodes.h @@ -494,10 +494,9 @@ namespace ISD { // Operand #last: Optional, an incoming flag.
