Andrew Trick cbc845f9cf Add pass printer passes in the right place. ... The pass pointer should never be referenced after sending it to schedulePass(), which may delete the pass. To fix this bug I had to clean up the design leading to more goodness. You may notice now that any non-analysis pass is printed. So things like loop-simplify and lcssa show up, while target lib, target data, alias analysis do not show up. Normally, analysis don't mutate the IR, but you can now check this by using both -print-after and -print-before. The effects of analysis will now show up in between the two. The llc path is still in bad shape. But I'll be improving it in my next checkin. Meanwhile, print-machineinstrs still works the same way. With print-before/after, many llc passes that were not printed before now are, some of these should be converted to analysis. A few very important passes, isel and scheduler, are not properly initialized, so not printed. llvm-svn: 149480		2012-02-01 07:16:20 +00:00
