I think I hit a C-Backend bug, where the IR works fine through the x86 <br>native code generator, but the LLVM IR -> C Backend -> x86 gcc path <br>gives core dump when trying to execute with the same inputs.<br><br>Where can I file a bug?<br><br>Is there any document about LLVM's C Backend other than reading its <br>source code?<br><br>Thank you<br><br>Chuck<br><br><br>_______________________________________________<br>LLVM Developers mailing list<br><a ymailto="mailto:LLVMdev@cs.uiuc.edu" href="mailto:LLVMdev@cs.uiuc.edu">LLVMdev@cs.uiuc.edu</a> http://llvm.cs.uiuc.edu<br>http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev<br><br><br></div></div></div><br>
