[LLVMdev] Selecting FrameIndex
...ch has a FrameIndex operand
(this results from a store to an int array in the source).
But there is no explicit pattern to match FrameIndex in the .td files,
even though I've specified 'frameindex' in the 'roots' of the
addressing mode ComplexPattern. The result is that I get a
CannotYetSelect on the FrameIndex operand during selection.
Anyone know what i'm doing wrong?

[LLVMdev] [PATCH] SelectionDAG Debugging
This patch adds a couple of interfaces to dump full or partial
SelectionDAGs. The current code only prints the top-level
SDNode. This patch makes it much easier to understand
CannotYetSelect errors and those sorts of things. In particular,
it helped me track down PR6019.
Any objections to committing?

Is it ever desirable to pass false to the "limit" argument?
Otherwise this looks ok.

[LLVMdev] [cfe-dev] Clang error
...rks for us.
Also, can you try to produce a proper backtrace by enabling core
dump and inspecting it with gdb so I can see if it matches ours.
For some reason I get an illegal SDNode to the Select() which crashes
when being dumped (which actually causes the segfault also for me as
it propagates to CannotYetSelect() which tries to dump it).
Makes it nasty to debug.
