similar to: Building libjpeg-turbo with LTO

Adding a couple of lld folks. I helped Shishir debug this, the link line looked like: /home/sjessu/build/bin/clang -O0 -flto -o jcstest jcstest.o ./.libs/libjpeg.a and the issue was that libjpeg.a was created with the system ar instead of llvm-ar. It worked when recreating libjpeg.a with llvm-ar. I noticed that the lld code has some special handling for the case when there is a missing

Hi David, Sure! Here's a function in sqlite3 called verifyDbFile, compiled with -O3. This is what it looks like when the intermediate bitcode is emitted by clang: link <https://pastebin.com/L3PrK1ac> And here's what happens after I run opt -O3 (no additional command-line arguments) on the file containing this function: link <https://pastebin.com/rZHBm2iU>. I'm not 100%

Hi David, By "dead" do you mean unreachable? My understanding was that the removal of dead code is simply another optimization, which should be disabled after adding "optnone" (and adding the function to llvm.used so the function doesn't later get deleted entirely). I am instrumenting certain basic blocks in an LLVM pass, and would like to compile a binary which

Hello, I am adding function calls to an LLVM link-time optimization (LTO) pass, using the IRBuilder::CreateCall method. I want these calls to remain in the final x86 binary at any optimization level, but on levels -O2 and -O3, some of these calls are being optimized out. So far, I've tried adding each function in the program (excluding LLVM intrinsics) to the llvm.used set, and I've also

Hello, I am adding to an LLVM pass that requires a filename as input. I am able to input this filename as a command line argument when I invoke this pass using opt, but I ultimately need to pass this argument to my code when I compile code with clang. How can I pass this argument to clang so that I can use it in my LLVM pass? Thanks for your help! Best, Shishir Jessu -------------- next part

Hi, I am looking into Control-Flow Integrity for indirect function calls, implemented with jump tables. I want to step through the code that produces these jump tables in GDB. I have built clang and opt from source with debugging symbols. I believe this code lives in llvm/lib/Transforms/LowerTypeTests.cpp, but when I try to debug *opt* by running the command "run -lowertypetests cfi-icall.bc

Hello, I am compiling a program with debugging information, and am attempting to extract !dbg numbers from function calls in LLVM IR. However, I've found a few inconsistencies. For example, this call exists in my module: %1 = tail call i1 @llvm.type.test(i8* bitcast (i32 (i32)* @_Z5otheri to i8*), metadata !"_ZTSFiiE") #5, *!dbg !69*, !nosanitize !2 I would like to extract the 69

I agree that the ArrayRef is likely the issue. I've debugged a crash caused by a temporary ArrayRef like that a couple times. Either do what David suggested or use a normal array: Metadata *mdArray[] = {ConstantInt::get(Int64Ty, 0), newMD}; ~Craig On Thu, Apr 30, 2020 at 9:56 AM David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > > > On Thu, Apr 30, 2020 at

Hi. I'm using llvm DataFlowSanitizer. I add such code in library libtiff. dfsan_label lt_label = dfsan_create_label("buf_offset", 0); dfsan_set_label(lt_label, (unsigned char *)buf, size); But when i compile libtiff with "-fsanitize=dataflow" option, then there is an error as follows: ../libtiff/libtiff.so.5.2.5: undefined reference to `dfs$jbg_enc_init'

Hi, I have made some changes in the LowerTypeTests Pass of opt, and would like to use these changes with the clang version I have downloaded. I compiled clang and llvm from scratch, made my changes in LowerTypeTests.cpp, and recompiled clang and opt. When I run clang with the appropriate flags to invoke the pass, it invokes the pass as originally written, but when I run opt on the relevant

Hello, I am editing the LowerTypeTests pass in LLVM, and part of my additions include the following 3 lines of code: // newTypeName is a std::string MDString* newMD = MDString::get(M.getContext(), newTypeName); ArrayRef<Metadata*> mdArray {ConstantInt::get(Int64Ty, 0), newMD}; auto* node = MDTuple::get(M.getContext(), mdArray); Thus far, I have been developing on a version of Clang with

I'm trying to get hplip-2.7.12 installed, and I'm reasonably sure that I had it installed on this box before my problems last month. Anyway, it will not build at the moment. It stops the Configure with "configure: error: "cannot find libjpeg support". However, Package libjpeg - 6b-37.i386 is already installed. Similarly, attempting to install hplip-3.9.2 stops with

Simon, Did you get a chance to review your AIX configuration? I'd be curious to know the differences with my own as while I have R installed, I still get the error related to libjpeg.a.
