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".

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().
