    • shrink-wrap: Once more PRs 67778, 68634, and now 68909 · 52ad5601 
      If a candidate PRE cannot get the prologue because a block BB is
reachable from it, but PRE does not dominate BB, we try again with the
dominators of PRE.  That "try again" needs to again consider BB though,
we aren't done with it.

    • libiberty: {count,dup,write}argv: constify argv input slightly · 66f49f07 
      Would be more useful if we could use "const char * const *", but there's
a long standing bug where gcc warns about incompatible pointers when you
try to pass in "char **".  We can at least constify the array itself as
gcc will not warn in that case.

    • Add vector_memory_operand and "Bm" constraint · 3f50525d
