- by vg_regtest for determining if a directory name matches an architecture; - by various .vgtest files for detecting x86/AMD64 features. This commit splits it in two for the two different purposes, which makes things clearer. Specific changes - Moved the x86/AMD64 feature detection stuff out of arch_test.c, and into the new x86_amd64_feature.c. Updated the relevant .vgtest files for the change. - In vg_regtest, now a prereq command must return 0 (prereq satisfied) or 1 (prereq not satisfied). Anything else makes vg_regtest abort. This makes obvious any problems with prereq tests rather than just making the tests skip innocuously. (We previously had exactly such a problem on the DARWIN branch; the x86 feature detection tests caused segfaults so the tests were incorrectly skipped. This change will catch any similar future problem.) - Changed os_test from a script to a C program, matching cpu_test. - Removed some unintentional darwin stuff from platform_test. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@9316
