Functions and variables that are exported by the IPA DSO (that GDBserver needs to look up) should have "C" mangling, thus be declared with extern "C". Function and variable declarations need the extern "C" marker, but variable definitions can't be marked extern, so the patch splits IP_AGENT_EXPORT into three. Building in C++ mode revealed that a few variables were missing IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C mode... So this ends being a bug fix as well. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * common/agent.h (IPA_SYM_EXPORTED_NAME): New. (IPA_SYM): Use it. * common/common-defs.h (EXTERN_C_PUSH, EXTERN_C_POP): New macros. gdb/gdbserver/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * linux-amd64-ipa.c (gdb_agent_get_raw_reg): Use IP_AGENT_EXPORT_FUNC. * linux-i386-ipa.c (gdb_agent_get_raw_reg): Use IP_AGENT_EXPORT_FUNC. * tracepoint.c (ATTR_USED, ATTR_NOINLINE, ATTR_CONSTRUCTOR) (IP_AGENT_EXPORT): Delete.
