# Code in Makefile.am will invoke this script with two arguments.
# The first is a GOARCH value.  The second is a keyword.
# The script will print the value of that keyword for that GOARCH.
# Keywords:
# - bigendian: true or false
# - cachelinesize: the cache line size in bytes
#	(for performance only; it's not essential to get this right)
# - defaultphyspagesize: the default physical page size in bytes
#	(not currently used, but maybe some day)
# - family: the processor family, from ALLGOARCHFAMILY in configure.ac
# - int64align: alignment of int64 type in bytes
# - maxalign: maximum alignment of values of Go types in bytes
# - minframesize: size of smallest possible function frame in bytes
#	(not currently used, may never be used)
# - pcquantum: minimum size of a single instruction in bytes
# - ptrsize: size of a pointer in bytes
