# 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_xmltarget       The XML source file to use for target.xml, if any.
#   srv_xmlfiles        Any other XML files which should be available for
#                       gdbserver in this configuration.
#
# 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
srv_hostio_err_objs="hostio-errno.o"

# Input is taken from the "${target}" variable.
