I am trying to compile llvm gcc 4.0 from svn today and I'm getting the error below. It looks like the file LLVMBuilder.h.

Okay, I'm past the GEP "have to dereference pointer first" problem of my last post. I now have a linkage error (I get undefined symbol when I try to assemble the program). gcc -o test.o test.s says: > /tmp/cczhiFk7.o(.text+0x7): In function `a': > : undefined reference to `_index_' _index_ is defined like this: > %_index_ = external global long ;

There wouldn't happen to be an index telling one which libraries define which symbols, would there? For example, if I'm told alvm.o: In function `llvm::Function::Create(llvm::FunctionType const*, llvm::GlobalValue::LinkageTypes, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, llvm::Module*)':

I am using llvm-2.6. In the online documentation, the signature is GlobalVariable::GlobalVariable ( const Type * Ty, bool isConstant, LinkageTypes Linkage, Constant * Initializer = 0, const Twine & Name = "", bool ThreadLocal = false, unsigned AddressSpace = 0 ) the link to the documenation is

Sorry to keep this thread alive, but I'm learning so ... There is more. The doc for GlobalValue::LinkageTypes or the C API LLVMLinkage is not as clear as the lang ref manual. See: http://llvm.org/docs/LangRef.html#linkage. I'm pointing this out because something like LinkerPrivateLinkage (LLVMLinkerPrivateLinkage), or another one, might be more appropriate to your throw away use case (if

I did a RelWithDebInfo + asserts build of LLVM just now and, when running "make check" under Valgrind, am seeing a lot of uses of uninitialized memory like the one below. Anyone know offhand what's likely to be the root cause? Unfortunately a Debug build doesn't give these errors. Thanks, John FAIL: LLVM :: Analysis/BasicAA/pr18573.ll (2093 of 18733)

Hello, while improving and extending support for dllexport/import I have noticed that the current way these are implemented is problematic and I would like some input on how to proceed. Currently dllexport/dllimport is treated as linkage type. This conflicts with inlined functions because there is no linkage for the combination of both. On first though, combining both doesn't make sense, but

So instead of using linkagetypes.weak I should use externalweaklinkage ? Le 11 févr. 2014 18:29, "Reid Kleckner" <rnk at google.com> a écrit : > You'd have to use extern_weak linkage.

The problem is that ThinLTO is not dropping the non-prevailing definitions, and they end up being emitted into the object file for b.o. $ ../ra/bin/llvm-dis -o - b.o0.0.preopt.bc | grep __llvm_prof $__llvm_profile_raw_version = comdat any $__llvm_profile_filename = comdat any @__llvm_profile_raw_version = constant i64 72057594037927940, comdat @__llvm_profile_filename = constant [19 x i8]

Thanks Peter, your patch does fix the reproducer. I filed https://bugs.llvm.org/show_bug.cgi?id=37422 to track this bug. I have no clue on how to resolve the tests - whether further cleanup is required in the code or in the tests. But if Teresa or you cannot get to it, I can, with some help, take a crack at fixing the tests. On Wed, May 9, 2018 at 11:26 AM Peter Collingbourne <peter at

Well, it looks like almost all of the problems go away when I build using trunk instead of 3.9. So, that was scary but I'm going to forget it ever happened. >8000 test cases failed under Valgrind!!

Hi, could anybody explain what GlobalValue::AvailableExternallyLinkage means? I implemented an instrumentation pass that creates a clone of a function. For some programs I noticed that also function such as “atoi”, “atof”, “__strspn_c2”, etc. they get cloned even if I am not implementing them in the module. I would like to avoid cloning those functions, so I noticed that they have

Thank you Chris. I am using llvm-3.4.2. I am facing the same issue when using clang++ as well. $ clang++ try.cpp -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS `llvm-config --cxxflags --ldflags --libs` -S -emit-llvm gives me errors $clang++ try.cpp -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS -S -emit-llvm $ lli try.s gives me Program used external function

Hi Nico, Reid, and Anton, I missed the discussion when I implemented dllexport/dllimport for our local tree. I essentially implemented your approach#1. I was trying to avoid the various external_linkage + some_attribute approaches because it seems that external_linkage would imply the external linkage without the dllimport/dllexport semantics, and there may be existing compiler codes that rely on
