@llvm/pr-subscribers-clang-codegen Author: None (MacroModel) Changeswhen Ty.isDependentType() is true, it will crash here: I encountered it while compiling my own project, which may not be the right solution, but prevents crashes Starting program: /home/MacroModel/llvm-debug-install/bin/clang-21 -c -Qunused-arguments -m64 -g -Wall -Wextra -Werror -O0 -std=c++26 -Ithird-parties/fast_io/include

I encountered this problem when compiling my own project. git clone https://github.com/MacroModel/uwvm2.git --depth=1
cd uwvm2
xmake f -m debug --use-llvm=y
xmake -vCompiling this project can at least reveal that there are multiple bugs in LLVM. |

There was a problem hiding this comment.
Even if this fixes the crash, the resulting code likely won't work; we need to compute the type to emit correct code.
The underlying issue is probably an issue with template instantiation (clang/lib/Sema). When a template is instantiated, all the depending types are supposed to be transformed into non-dependent types. But there are occasionally bugs where this sort of issue slips through.
Please file a bug with a testcase (see https://llvm.org/docs/HowToSubmitABug.html)

I encountered such problems because I used the module. The post-processed files contain only a few contents and it's impossible to minimize and restore them to their original state. |

I'm not really sure how to go about reducing a testcase in that case; it's not something I've ever run into myself. Please post on Discourse (https://discourse.llvm.org/); maybe someone else has some ideas. |

Also, if you're okay with publicly posting your code, it's fine to file a bug with an unreduced testcase. |

When I rewrote the project all in header+cpp and wrote all the cppm all in header's mode, the bug no longer existed. I think llvm needs to enhance the cxx module reporting mechanism, such as generating a merged cxx module storage file for reporting feedback |

when Ty.isDependentType() is true, it will crash here:
I encountered it while compiling my own project, which may not be the right solution, but prevents crashes
