[LLVMdev] question on instruction selection
...nodes that one needs to match against? And what's the
algorithm behind this selection DAG?
I'm also wondering what would be the possible improvement of the approach
presented last Friday at POPL
(http://portal.acm.org/citation.cfm?doid=1706299.1706346 or
http://www.eecs.tufts.edu/~dias/gentileset.pdf) for LLVM. Any insight? The
approach seems similar to what gcc does or did at least (IR->RTL->ASM), so
I'm not entirely sure there would be something to gain here for LLVM. It
would be nice to generate the selection dag from LLVM IR automatically,
though.
Thanks,
Nuno

...n DAG?
The underlying algorithm is a fairly simple bottom-up tiling.

...more documentation than I though :) Thanks
for the pointers.
