2 Julian Seward was the original founder, designer and author of
3 Valgrind, created the dynamic translation frameworks, wrote Memcheck,
4 the 3.X versions of Helgrind, SGCheck, DHAT, and did lots of other
7 Nicholas Nethercote did the core/tool generalisation, wrote
8 Cachegrind and Massif, and tons of other stuff.
10 Tom Hughes did a vast number of bug fixes, helped out with support for
11 more recent Linux/glibc versions, set up the present build system, and has
12 helped out with test and build machines.
14 Jeremy Fitzhardinge wrote Helgrind (in the 2.X line) and totally
15 overhauled low-level syscall/signal and address space layout stuff,
16 among many other things.
18 Josef Weidendorfer wrote and maintains Callgrind and the associated
21 Paul Mackerras did a lot of the initial per-architecture factoring
22 that forms the basis of the 3.0 line and was also seen in 2.4.0.
23 He also did UCode-based dynamic translation support for PowerPC, and
24 created a set of ppc-linux derivatives of the 2.X release line.
26 Greg Parker wrote the Mac OS X port.
28 Dirk Mueller contributed the malloc/free mismatch checking
29 and other bits and pieces, and acts as our KDE liaison.
31 Robert Walsh added file descriptor leakage checking, new library
32 interception machinery, support for client allocation pools, and minor
35 Bart Van Assche wrote and maintains DRD.
37 Cerion Armour-Brown worked on PowerPC instruction set support in the
38 Vex dynamic-translation framework. Maynard Johnson improved the
41 Kirill Batuzov and Dmitry Zhurikhin did the NEON instruction set
42 support for ARM. Donna Robinson did the v6 media instruction support.
44 Donna Robinson created and maintains the very excellent

49 Frederic Gobry helped with autoconf and automake.
51 Daniel Berlin modified readelf's dwarf2 source line reader, written by Nick
52 Clifton, for use in Valgrind.o

57 David Woodhouse has helped out with test and build machines over the course
60 Florian Krohm and Christian Borntraeger wrote and maintain the
61 S390X/Linux port. Florian improved and ruggedised the regression test
64 Philippe Waroquiers wrote and maintains the embedded GDB server. He
65 also made a bunch of performance and memory-reduction fixes across
66 diverse parts of the system.
68 Carl Love and Maynard Johnson contributed IBM Power6 and Power7
69 support, and generally deal with ppc{32,64}-linux issues.
71 Petar Jovanovic and Dejan Jevtic wrote and maintain the mips32-linux
74 Dragos Tatulea modified the arm-android port so it also works on
77 Jakub Jelinek helped out with the AVX support.
79 Many, many people sent bug reports, patches, and helpful feedback.
