[llvm-dev] ADDING A CUSTOM INSTRINSIC

[Sayantan Majumdar via llvm-dev]

Hello all. I am new to LLVM. I have added a custom intrinsic *foo* by
creating a new folder in *lib/Target/Foo* and creating a new file *Foo.td*.
I then built the entire llvm project and the intrinsic *foo* has been added
successfully. But I am unable to figure out how to add the pseudo
instruction for it. For example if I want my intrinsic foo to perform
multiplication of two integers, where should I add this instruction? I have
googled a lot and couldn't find anything concrete.
