[llvm-dev] Efficient emulation of arithmetic operations

[Alex Susu via llvm-dev]

   Hello.
     I would like to advertise a very interesting LLVM related project I worked on in the 
last 1.5 years.

     It is about the efficient emulation of arithmetic operations by "inlining" the 
emulation routines (written manually) by using the LLVM Instruction selection pass.
     This is something that is useful as methodology for other LLVM back ends for 
architectures that require emulation. The technical report at 
https://sites.google.com/site/alexsusu/myfilecabinet/OpincaaLLVM_TR_UPB.pdf describes this 
very interesting method in Section 7 - specifically Algorithm 7.1 could be used by other 
LLVM developers to implement it for other back ends also.
     (There are also some slides available describing specifically this work: 
https://sites.google.com/site/alexsusu/myfilecabinet/CGO2019_LLVM_Performance_Workshop-Arithmetic_emulation_slides.pdf 
) .

     Please ask questions and provide feedback if this is of interest to you.

   Thank you,
     Alex
