/* * Implement addr2line() using libLLVM. LLVM is a C++ API, and * many of the linux/ headers cannot be included in a C++ compile unit, * so we need to make a little bridge code here. llvm_addr2line() will * convert the inline frame information from LLVM's internal structures * and put them into a flat array given in inline_frames. The caller * is then responsible for taking that array and convert it into perf's * regular inline frame structures (which depend on e.g. struct list_head). * * If the address could not be resolved, or an error occurred (e.g. OOM), * returns 0. Otherwise, returns the number of inline frames (which means 1 * if the address was not part of an inlined function). If unwind_inlines * is set and the return code is nonzero, inline_frames will be set to * a newly allocated array with that length. The caller is then responsible * for freeing both the strings and the array itself.
