Description Jakub Jelinek 2011-12-16 11:12:09 UTC 
sha1.go (and other cryptos) fail to bootstrap at least on i686-linux, with:
../../../libgo/go/crypto/sha1/sha1.go: In function ‘sha1.Sum.pN24_libgo_crypto.sha1.digest’:
../../../libgo/go/crypto/sha1/sha1.go:82:1: error: statement marked for throw, but doesn’t
# .MEM_130 = VDEF <.MEM_80>
*tmp_8[0] = iftmp.106_128;
