From 9293fc4185bc737303f0114936ca9a7f467a7bcc Mon Sep 17 00:00:00 2001 From: Siva Chandra Date: Thu, 7 Jan 2016 23:32:34 +0000 Subject: Better scheme to lookup alternate mangled name when looking up function address. Summary: This change is relevant for inferiors compiled with GCC. GCC does not emit complete debug info for std::basic_string<...>, and consequently, Clang (the LLDB compiler) does not generate correct mangled names for certain functions. This change removes the hard-coded alternate names in ItaniumABILanguageRuntime.cpp. Before the hard-coded names were put in ItaniumABILanguageRuntime.cpp, one could not evaluate std::string methods (ex. std::string::length). After putting in the hard-coded names, one could evaluate them. However, it did not still enable one to call methods on, say for example, std::vector. This change makes that possible. There is some amount of incompleteness in this change. Consider the following example: std::string hello("hello"), world("world"); std::map m; m[hello] = world; One can still not evaluate the expression "m[hello]" in LLDB. Will address this issue in another pass.
