To do that, this patch makes IPA compile safe-strerror as well. Because it doesn't use Gnulib, it calls the Glibc version of strerror_r directly. Consequently this patch also removes the configure checks for strerror. gdb/ChangeLog: 2019-12-10 Christian Biesinger <cbiesinger@google.com> * config.in: Regenerate. * configure: Regenerate. * gdbsupport/agent.c (gdb_connect_sync_socket): Call safe_strerror instead of strerror. * gdbsupport/common.m4: Don't check for strerror. * gdbsupport/safe-strerror.c: Support both the glibc version of strerror_r and the XSI version. gdb/gdbserver/ChangeLog: 2019-12-10 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Add safe-strerror.c to gdbreplay and IPA, and change UNDO_GNULIB_CFLAGS to undo strerror_r instead of strerror. * config.in: Regenerate. * configure: Regenerate. * configure.ac: Don't check for strerror. * linux-i386-ipa.c (initialize_fast_tracepoint_trampoline_buffer): Call safe_strerror instead of strerror. * server.h (strerror): Remove this now-unnecessary declaration. * tracepoint.c (init_named_socket): Call safe_strerror instead of strerror. (gdb_agent_helper_thread): Likewise. * utils.c (perror_with_name): Likewise. Change-Id: I74848f072dcde75cb55c435ef9398dc8f958cd73
