Updated dependencies: * GMP 6.2.1 * ISL 0.24 * MPL 1.2.1 * MPFR 4.1.0 The dependencies were pulled in by running the ./contrib/download_prerequisites script and then manually removing the symbolic links and archives, and renaming the directories (i.e mv isl-0.24 to isl)

# 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
