gdb/riscv: Add target description support

[deliverable/binutils-gdb.git] / gdb / configure.tgt

# Mappings from configurations to GDB target definitions.  This is
# invoked from the autoconf generated configure script.

# This file sets the following shell variables:
#  gdb_target_obs	target-specific object files to use
#  gdb_sim		simulator library for target
#  gdb_osabi		default OS ABI to use with target
#  build_gdbserver	set to "yes" if gdbserver supports target
#  gdb_have_gcore	set to "true"/"false" if this target can run gcore

# NOTE: Every file added to a gdb_target_obs variable for any target here
#       must also be added to either ALL_TARGET_OBS or ALL_64_TARGET_OBS
#	in Makefile.in!
