From: Chris Lattner Date: Sun, 13 Oct 2002 20:57:00 +0000 (+0000) Subject: - Change Function's so that their argument list is populated when they are X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;ds=sidebyside;h=69da5cf26143e4542d4bf8c78ffac6d079efe5c9;p=oota-llvm.git - Change Function's so that their argument list is populated when they are constructed. Before, external functions would have an empty argument list, now a Function ALWAYS has a populated argument list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4149 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/AsmParser/llvmAsmParser.y b/lib/AsmParser/llvmAsmParser.y index 8613a413ca4..52ef6907f29 100644 --- a/lib/AsmParser/llvmAsmParser.y +++ b/lib/AsmParser/llvmAsmParser.y @@ -602,7 +602,7 @@ Module *RunVMAsmParser(const string &Filename, FILE *F) { %union { Module *ModuleVal;
