Hi all, I saw C++ frames in `jhsdb jstack --mixed`, and they were mangled as below:
0x00007ff255a8fa4c _ZN9JavaCalls11call_helperEP9JavaValueRK12methodHandleP17JavaCallArgumentsP6Thread + 0x6ac 0x00007ff255a8cc1d _ZN9JavaCalls12call_virtualEP9JavaValueP5KlassP6SymbolS5_P17JavaCallArgumentsP6Thread + 0x33d We can demangle them via c++filt, but I think it is more convenience if jstack can show demangling symbols. I think we can demangle in jstack with this patch. If it is accepted, I will file it to JBS and send review request. What do you think? http://cr.openjdk.java.net/~ysuenaga/sa-demangle/ We can get the stack as below after applying this patch: 0x00007ff1aba20a4c JavaCalls::call_helper(JavaValue*, methodHandle const&, JavaCallArguments*, Thread*) + 0x6ac 0x00007ff1aba1dc1d JavaCalls::call_virtual(JavaValue*, Klass*, Symbol*, Symbol*, JavaCallArguments*, Thread*) + 0x33d I use abi::__cxa_demangle() for demangling, so this patch adds C++ source to SA. If it is not comfortable, we can use cplus_demangle(). But this function is provided by libiberty.a, so we need to link it to libsaproc and need to check libiberty.a in configure script. Thanks, Yasumasa
