From: David Blaikie Date: Fri, 8 Mar 2013 18:17:46 +0000 (+0000) Subject: Remove -print-dbginfo as it is unused & bitrotten. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=423de3f0478fd8e4f8aa650d8cf9f64d08963118;p=oota-llvm.git Remove -print-dbginfo as it is unused & bitrotten. This pass hasn't been touched in two years & would fail with assertions against the current debug info metadata format (the only test case for it still uses a many-versions old debug info metadata format) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176707 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/include/llvm/Analysis/Passes.h b/include/llvm/Analysis/Passes.h index 27726f49bcc..ae117135db9 100644 --- a/include/llvm/Analysis/Passes.h +++ b/include/llvm/Analysis/Passes.h @@ -198,9 +198,6 @@ namespace llvm { // analyze.
