- This work was presented at the LLVM Dev Meeting in 2013
- (http://llvm.org/devmtg/2013-11/#talk3). A more detailed description was
- published in a paper at LCTES 2014
- (http://dl.acm.org/citation.cfm?id=2597811). The code was released to the
- community at the time. Meanwhile, the pass has been in production use at
- QuIC for the past few years and has been actively maintained internally. In
- order to magnify the impact of MergeSimilarFunctions, it has been ported to
- ThinLTO and the patches have been upstreamed (see stack of 5 patches:
- https://reviews.llvm.org/D52896). But instead of replacing the existing
- MergeFunctions pass in LLVM-upstream the community suggested we improve the
- existing one with the ideas from MergeSimilarFunctions. And then leverage
- the ThinLTO on top of that. The MergeSimilarFunction used in ThinLTO gives
- impressive code size reduction across a wide range of workloads and the work
- was presented at LLVM-dev 2018
- (https://llvm.org/devmtg/2018-10/talk-abstracts.html#talk2). The LLVM
- project would greatly benefit from this code size optimization as most
- embedded systems (think SmartPhones) applications are constrained on
- code-size.
