The PR reports that building with -Wodr -flto complains about different versions of struct ipa_sym_addresses, in common/agent.c and gdbserver/tracepoint.c. This patch renames the version in common to ipa_sym_addresses_common to avoid the name clash. Because the IPA_SYM assumed the name ipa_sym_addresses, it now requires the includer to define the IPA_SYM_STRUCT_NAME macro to define the name of the structure holding the IPA symbol addresses. gdb/ChangeLog: PR build/23399 * common/agent.c (IPA_SYM_STRUCT_NAME): Define. (struct ipa_sym_addresses): Rename to... (struct ipa_sym_addresses_common): ... this. * common/agent.h (IPA_SYM): Use IPA_SYM_STRUCT_NAME. gdb/gdbserver/ChangeLog: PR build/23399 * tracepoint.c (IPA_SYM_STRUCT_NAME): Define.
