# Some generic MIPS tests
#

# When adding a new test to this file, try to do the following things:
#
# * If testing assembly and disassembly of code, don't forget to test
# the actual bit encodings of the instructions (using the
# --show-raw-insn flag to objdump). 
#
# * Try to run the test for as many architectures as appropriate,
# using the "run_dump_test_arches" or "run_list_test_arches" functions,
# along with the output from a call to "mips_arch_list_matching."
#
# * Be sure to compare the test output before and after your testsuite
# changes, to verify that existing and new tests were run as expected.
# Look for expect ERROR messages in the testsuite .log file to make sure
# the new expect code did not contain errors.

# To add support for a new CPU to this file, add an appropriate entry
# to the sequence of "mips_arch_create" function calls below, and test
# the result.  The new CPU should automatically be used when running
# various tests.  If the new CPU is the default CPU for any tool
# targets, make sure the call to "mips_arch_create" reflects that fact.


# "LOSE" marks information about tests which fail at a particular point
# in time, but which are not XFAILed.  Either they used to pass
# and indicate either regressions or the need to tweak the tests to keep
# up the with code, or they are new tests and it is unknown whether or not
# they should pass as-is for the given object formats.


# The functions below create and manipulate an "architecture data
# array" which contains entries for each MIPS architecture (or CPU)
# known to these tests.  The array contains the following information
# for each architecture, indexed by the name of the architecture
# described by the entry:
#
# displayname: The name of the entry to be used for pretty-printing.
#
# gprsize: The size in bits of General Purpose Registers provided by
# the architecture (must be 32 or 64).
#
# props: A list of text strings which are associated with the
# architecture.  These include the architecture name as well as
# information about what instructions the CPU supports.  When matching
# based on properties, an additional property is added to the normal
# property list, "gpr<gprsize>" so that tests can match CPUs which
# have GPRs of a specific size.  The following properties are most
# useful when matching properties for generic (i.e., not CPU-specific)
# tests:
#
#	mips1, mips2, mips3, mips4, mips5, mips32, mips64
#		The architecture includes the instructions defined
#		by that MIPS ISA.
#
#	fpisa3, fpisa4, fpisa5
#		The architecture includes the floating-point
#		instructions defined by that MIPS ISA.
#
#	gpr_ilocks
#		The architecture interlocks GPRs accesses.  (That is,
#		there are no load delay slots.)
#
#	mips3d	The architecture includes the MIPS-3D ASE.
#
#	ror	The architecture includes hardware rotate instructions.
#
#	gpr32, gpr64
#		The architecture provides 32- or 64-bit General Purpose
#		Registers.
#
#	singlefloat
#		The CPU is 64 bit, but only supports 32 bit FPU.
#
#	nollsc
#		The CPU doesn't support ll, sc, lld and scd instructions.
#
# as_flags: The assembler flags used when assembling tests for this
# architecture.
#
# objdump_flags: The objdump flags used when disassembling tests for
# this architecture.
#
# Most entries in the architecture array will have values in all of
# the fields above.  One entry, "default" represents the default CPU
# based on the target of the assembler being built.  If always has
# empty "as_flags" and "objdump_flags."

#
# The new entry's property list is initialized to contain ARCH, any
# properties specified by PROPS, and the properties associated with
# the entry specified by EXTENDS.  (The new architecture is considered
# to extend the capabilities provided by that architecture.)
#
# If DEFAULT_FOR_TARGETS is specified, it is a list of targets for which
# this architecture is the default architecture.  If "istarget" returns
# true for any of the targets in the list, a "default" entry will be
# added to the architecture array which indicates that ARCH is the default
