Hi, I was evaluating all transformation passes and noticed a few things. In particular, I found three passes in the documentation that I can't seem to find any code for. Where these removed? Lower GC intrinsics, for GCless code generators (-lowergc) Correlated Expression Elimination (-cee) Lower select instructions to branches (-lowerselect) Additionally, I found the following passes for which no documentation was present: createGVExtractionPass() createStructRetPromotionPass() createStripDeadPrototypesPass()...

...e first, pass-comments.diff adds or improves the file comments for a number of passes. This patch is slightly interesting. The second, pass-doc.diff is mostly a yank-put job and updates Passes.html as follows. I've removed the following passes from the documentation: Lower GC intrinsics, for GCless code generators (-lowergc) Correlated Expression Elimination (-cee) Lower select instructions to branches (-lowerselect) lowers packed operations to operations on smaller packed datatypes (-lower-packed) (I didn't report the last one in my initial posting, though I had noticed it was missin...

For the field pointer, one could use the getelementptr instruction: %pairty = { sbyte, sbyte, int* } %pairPtr = ... %fieldptr = getelementptr
