# Mappings from configuration triplets to gdbserver build options.
# This is invoked from the autoconf-generated configure script, to
# produce the appropriate Makefile substitutions.
# This file sets the following shell variables:
# srv_regobj The register protocol appropriate for this target.
# srv_tgtobj Any other target-specific modules appropriate
# for this target.
# srv_hostio_err The object implementing the hostio_last_error
# target method.
# srv_xmlfiles All XML files which should be available for
# gdbserver in this configuration.
# ipa_obj Any other target-specific modules appropriate
# for this target's in-process agent.
#
# In addition, on GNU/Linux the following shell variables will be set:
# srv_linux_regsets Set to "yes" if ptrace(PTRACE_GETREGS) and friends
# may be available on this platform; unset otherwise.
# They will only be used if <sys/ptrace.h> defines
# PTRACE_GETREGS.
# srv_linux_usrregs Set to "yes" if we can get at registers via
# PTRACE_PEEKUSR / PTRACE_POKEUSR.
# Default hostio_last_error implementation
