From 7d4e9934e7ca83094c5cf41346966c8350179ff2 Mon Sep 17 00:00:00 2001 From: Andrew Trick Date: Wed, 18 Sep 2013 23:31:16 +0000 Subject: Encapsulate PassManager debug flags to avoid static init and cxa_exit. This puts all the global PassManager debugging flags, like -print-after-all and -time-passes, behind a managed static. This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190974 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/llvm-diff/llvm-diff.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'tools/llvm-diff') diff --git a/tools/llvm-diff/llvm-diff.cpp b/tools/llvm-diff/llvm-diff.cpp index f70219eaf5..62fc026327 100644 --- a/tools/llvm-diff/llvm-diff.cpp +++ b/tools/llvm-diff/llvm-diff.cpp @@ -20,6 +20,7 @@ #include "llvm/IR/Module.h" #include "llvm/IR/Type.h" #include "llvm/IRReader/IRReader.h" +#include "llvm/PassManager.h" #include "llvm/Support/CommandLine.h" #include "llvm/Support/MemoryBuffer.h" #include "llvm/Support/SourceMgr.h" @@ -67,6 +68,9 @@ static cl::list GlobalsToCompare(cl::Positional, cl::desc("")); int main(int argc, char **argv) { + // Initialize PassManager for -time-passes support. + initializePassManager(); + cl::ParseCommandLineOptions(argc, argv); LLVMContext Context; -- cgit v1.2.3
