[llvm-dev] Error-Running pass 'Function Pass Manager' on module
Hi, everyone, I use opt to optimize some .bc files, but in some cases, when I use a costume passes sequence, I get the following error 1.Running pass 'Function Pass Manager' on module 'xx.bc'. 2.Running pass 'Value Propagation' on function '@yy' Segmentation fault (core dumped) What are the reasons of this error? From the output text, I know that opt runs pass 'Function Pass Manager' on module, which is not correct, but I cannot find the reason. Or there are some cautions that I need to know when I define the passes sequence by myself? -------------- next part -------------- An HTML attachment was scrubbed...

For some cases, the following error also occurs 1. Running pass 'Interprocedural Sparse Conditional Constant Propagation' on module 'a.bc'. Segmentation fault (core dumped) In most case, opt reports 1 Running pass 'Function Pass Manager' on module 'xx.bc', 2 Running pass 'mmm' on function '@yy' Segmentation fault (core dumped) At 2018-11-01 20:15:27, "cszide via llvm-dev" <llvm-dev at lists.llvm.org> wrote: Hi, everyone, I use opt to optimize some .bc files, but in some cases, when I use a costume passes sequence, I get the following error 1.Running pass 'Function Pass Manager' on module 'xx.bc'. 2.Running pass 'Value Propagation' on function '@yy' Segmentation fault (core dumped) What are the reasons of this error?

[llvm-dev] Error-Running pass 'Function Pass Manager' on module
Have you tried building in Debug mode and reading asserts? What does the assert say?
