Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537 2009-09-11 20:01:28 +02:00			`; RUN: opt < %s -globalopt -S \| \`
Add unnamed_addr when we can show that address of a global is not used. llvm-svn: 123834 2011-01-19 17:32:21 +01:00			`; RUN: grep {G1 = internal unnamed_addr constant}`

rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. llvm-svn: 133337 2011-06-18 08:05:24 +02:00			`%Blah = alloca [58 x i8]`
