similar to: [LLVMdev] region pass - new pass for llvm

Some doxygen annotations are attached to the wrong entry, which can be misleading. This patch fixes the mistake everywhere I could find it. --- include/llvm/InstrTypes.h | 54 ++++++++++++++++++++-------------------- include/llvm/MC/MCDirectives.h | 42 +++++++++++++++--------------- include/llvm/Pass.h | 10 +++--- 3 files changed, 53 insertions(+), 53 deletions(-) diff

Dear Will, If you're seeing the wrong method executed, it's probably because you're using multiple inheritance in your analysis group (which is a very common thing to do). LLVM 2.7 made a change which alleviated the need for RTTI or some other undesirable C++ feature. However, it also broke multiple inheritance with analysis group passes. To fix it, your analysis group needs to

Building with MinGW-w64 GCC 5.3.0 via Makefile.lite, I get the following warnings: bitwriter.c: In function 'FLAC__bitwriter_write_utf8_uint64': bitwriter.c:324:19: warning: inlining failed in call to 'FLAC__bitwriter_write_raw_uint32.constprop': --param large-function-growth limit reached [-Winline] inline FLAC__bool FLAC__bitwriter_write_raw_uint32(FLAC__BitWriter *bw,

Hello LLVMdev, I’m using LLVM to do static analysis exclusively (without any code generation). To implement this analysis, I’m using multiple address spaces to disambiguate the purpose of the pointed memory. Since address spaces never alias in my model, I set on to implement an alias analysis pass that would exactly provide this information, as I’m seeing a couple of otherwise dead store that

Hi, i run NUT on a Raspberry Pi 3 Model B and after the latest OS Update i get the following Error from KFENCE, the current OS Version is the first with KFENCE so it possible that this Problem has was always existing.

Hi, Does your pass use multiple inheritance? Sounds like your problem is that you need to define getAdjustedAnalysisPointer, see: http://llvm.org/docs/doxygen/html/classllvm_1_1Pass.html#a03d3a81b1c46aff7c38ef3a6750ba225 An example implementation (very likely exactly what you want) is in LibCallAliasAnalysis: http://llvm.org/docs/doxygen/html/LibCallAliasAnalysis_8h_source.html#l00060 Hope

Hi all, I am using llvm to perform some static analysis with a module pass. In getAnalysisUsage(), I specified some required passes by: addRequiredTransitive<LoopInfo>(); When I run my pass using opt, it crashes with segmentation fault with callstack: #0 0x0877aebd in llvm::PMTopLevelManager::findAnalysisUsage (this=0x8c10934, P=0xb15b988) at PassManager.cpp:573 #1 0x0877aa9b in
