You not the first who raise this issue. The short answer: don't waste your time on this. AIUI, content of 'MPIR/tune/' folder is intended for MPIR Developers, not Users.
Longer by Torbjörn Granlund: We never ported timing things to WinDoS. One should not need to run any of the things in tune/ on non-Unix platforms. The important thing is to run it on each CPU type. (the full thread https://gmplib.org/list-archives/gmp-bugs/2015-December/003879.html ) Since GMP Developers don't care about running "GMP timing things" on Windows, it's hard to expect that "MPIR timing things" be very different (since they share the same limitations). Even in spite of all attempts of MPIR Developers to shave-off rough edges. Alexander -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
