...ust the always-inliner. There is no extension point offered which would not fall into this inliner's CGSCC pass manager, because we cannot even express such an extension point today. I've almost finished an interim[1] fix to this which will take the following form: 1) Introduce a new 'BarrierNoop' module pass which has no effect other than to go into the optimization pipeline, and terminate any of the implicitly nested pass managers in place. This will even be useful on the 'opt' commandline, for example to build two independent CGSCC pass managers. 2) Teach the -O0 extension p...

Dear all, I wrote a machine function pass to run with llc. But I get this error while building: "/home/erdem/llvm/lib/CodeGen/CodeGen.cpp:80: error: undefined reference to 'llvm::initializeNoopInserterPass(llvm::PassRegistry&)'" NoopInserter is the name of my pass. I already added this line to InitializePasses.h: "void

Hello, I've recently changed AddressSanitizer (asan) compiler pass from ModulePass to FunctionPass and it could a bit of mayhem. The problem is that asan FunctionPass instruments a function foo, then foo gets inlined into bar, then bar gets instrumented and thus the code of foo gets instrumented twice (which causes run-time crash). This happens only at -O0; at -O1 we get the correct order of
