This may seem like an odd question but I have spent some time looking at this and wondering. Assume that I have performed a full three stage bootstrap and then ran the testsuite. Assume that I was happy with the results and then ran the install. How do I know that the resultant compiler that is now in the --prefix=dir is also complete and "okay" ? The testsuite was run while the present working dir was the objdir. However after install we assume that everything lands correctly in the destination. Can we also run the testsuite *after* install and only with the compiler in the final install location? -- Dennis
