6// This program determines which architectures that this Valgrind installation
7// supports, which depends on the what was chosen at configure-time.  For
8// example, if Valgrind is installed on an AMD64 machine but has been
9// configured with --enable-only32bit then this program will match "x86" but
10// not "amd64".
11//
12// We return:
13// - 0 if the machine matches the asked-for arch
14// - 1 if it doesn't match but does match the name of another arch
15// - 2 if it doesn't match the name of any arch
16// - 3 if there was a usage error (it also prints an error message)
17
18// Nb: When updating this file for a new architecture, add the name to
19// 'all_archs' as well as adding go().
