[RFC 2/6] perf probe: Parse linerange for C++ functions

From: Holger Hans Peter Freyther perf probe --funcs will demangle C++ symbols by default but these functions can not be used for listing sourcecode. Modify the scanner to start searching for a line number only after a single ':'. ./perf probe -x ./cxx-example -L \

[RFC 1/6] perf probe: Do not exclude mangled C++ funcs

From: Holger Hans Peter Freyther Using --funcs --no-demangle on a C++ binary does not list any of the C++ functions. Change the default filter to not exclude the Common C++ ABI symbols. $ ./perf probe -x ./cxx-example --funcs --no-demangle ...

[RFC 3/6] perf probe: Make listing of C++ functions work

From: Holger Hans Peter Freyther If die_match_name does not match, attempt to demangle the linkage name. To use the generic demangling API we require to have a struct dso. Store it inside the debuginfo and pass it to the relevant callbacks. ./perf probe -x ./foo -L \

[RFC 0/6] perf probe: Attempt to improve C++ probing

From: Holger Hans Peter Freyther Currently perf probe -x app --funcs will list and demangle C++ functions but the other probe actions can't work with them. When asking probe to not demangle it will not list any of the application symbols creating the impression that

[RFC 6/6] perf probe: Make it possible to add a C++ uprobe

From: Holger Hans Peter Freyther If the linkage name looks like a common C++ ABI name use it instead of the original function name. This makes adding a uprobe for a C++ symbol possible. ./perf probe -x ./cxx-example "std::vector::at" Added new

[RFC 5/6] perf probe: Make listing of variables work for C++ functions

From: Holger Hans Peter Freyther Update call sites with die_match_name to call matches_demangled as well. This requires to pass the struct debuginfo/struct dso to the callbacks and modifies the closure/void *data parameter. For most functions this will change the

[RFC 4/6] perf probe: Show variables for C++ functions

From: Holger Hans Peter Freyther The demangled C++ function name contains spaces and using the generic argc_split would split the function in the middle. Create a separate version that counts the number of opening and closing '<', '>' for templated functions. $ ./perf
