From 4147f39769d404cab02da4beea852ad2600dadbb Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Fri, 5 Aug 2011 00:51:31 +0000 Subject: Temporarily revert r135528 which distinguishes between two copies of one inlined variable, based on the discussion in PR10542. This explodes the runtime of several passes down the pipeline due to a large number of "copies" remaining live across a large function. This only shows up with both debug and opt, but when it does it creates a many-minute compile when self-hosting LLVM+Clang. There are several other cases that show these types of regressions. All of this is tracked in PR10542, and progress is being made on fixing the issue. Once its addressed, the re-instated, but until then this restores the performance for self-hosting and other opt+debug builds. Devang, let me know if this causes any trouble, or impedes fixing it in any way, and thanks for working on this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136953 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfDebug.cpp | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) (limited to 'lib/CodeGen') diff --git a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index 4900e94310..0a3f75037b 100644 --- a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -1286,18 +1286,14 @@ void DwarfDebug::endModule() { } /// findAbstractVariable - Find abstract variable, if any, associated with Var. -DbgVariable *DwarfDebug::findAbstractVariable(DIVariable &DV, +DbgVariable *DwarfDebug::findAbstractVariable(DIVariable &Var, DebugLoc ScopeLoc) { - LLVMContext &Ctx = DV->getContext(); - - // More then one inlined variable corresponds to one abstract variable. - DIVariable Var = cleanseInlinedVariable(DV, Ctx); DbgVariable *AbsDbgVariable = AbstractVariables.lookup(Var); if (AbsDbgVariable) return AbsDbgVariable; - + LLVMContext &Ctx = Var->getContext(); DbgScope *Scope = AbstractScopes.lookup(ScopeLoc.getScope(Ctx)); if (!Scope) return NULL; -- cgit v1.2.3-70-g09d2
