Is there a VLIW support in LLVM? I found this, https://groups.google.com/forum/#!searchin/llvm-dev/VLIW, but it looks like it is not completely implemented. Specifically I'm interested in how instructions are bundled together. I can't seem to find it anywhere in the source code. Any help in resolving he issue is appreciated. -------------- next part -------------- An HTML attachment was scrubbed...

Hi Rail,
For the VLIW support, Qualcomm's Hexagon target is a good reference.

Kun, Thanks for the reply. I looked at it, but wasn't able to find where actual instruction bundling takes place, i.e. where exactly in the code they pack instruction into a single bundle. Do you know where it is done? I would really appreciate any pointers. Thanks.
