Authors

MPIR has been developed since 2008 by a large number of people.

The authors of MPIR to date (including code merged from the main GMP project since MPIR 1.0):

• Brian Gladman - Windows MSVC port and intel format x86_64 code
• Jason Moxham - Very significant and extensive improvements to the assembly code on numerous processors.
• William Hart - Build system modifications and intel format x86_64 code, some work on Toom 4 and Toom 7 code, extended GCD version of Möller's fast GCD code
• Pierrick Gaudry - AMD 64 assembly support, revised FFT code
• Gonzalo Tornaria - Patches to config.guess, cpuid.c and help with build testing
