I started learning/working on the Rust compiler very recently. The command line to compile rust code with rustc has multiple code gen options, one of which is llvm-args, which allows the user to specify the configuration of the LLVM-backend. I want to add a new flag to llvm-args, but struggle to come up with an implementation plan.
I have looked at some PRs on the Rust repo (PRs 41847 and 27260) where people try to create new flags for the Rust compiler, but still couldn't map out a procedure that I should follow to complete my task. I would greatly appreciate any guidance on this topic.

I have being thinking lately on how people do tech stuff. Learn and apply require choices, sometimes trial and error. Other times, the trial and errors are so frustrating or even blindfolded that I just give up and blame tech-gods. Regardless of this sobbing introduciton, here is my attempt to improve the test coverage on my boilerplate express-based NodeJS sappio.
Questions:
I found this jest-express tool, but started with library supertest;
Some methods (check src/core/utils/error-handler.js or src/core/controllers) does not change its test coverage regardless of how many tests I write.
There are other (apparently naive) questions which I can ennumerate here. However, most readers are very sensitive about many questions without financial feedback. :-/

there are *.pdl files defined in aosp source build tree which during compilation a cc host binary "bluetooth_packetgen" will convert these files to Rust code.
https://cs.android.com/android/platform/superproject/+/master:external/uwb/src/rust/uwb_uci_packets/uci_packets.pdl
I did not find any docs related to *.pdl format files in aosp, can anyone explain the background of *.pdl files and how these are getting converted into rust code
Edit: Understood some from cs.android.com

I am trying to write and execute the C code program for data communication. Please can anyone help me in writing the Program for HLS?
Tried in normal C code program like using PRINTF and SCANF statements but it's showing a compilation error.
When you use HLS you are going to "translate" your C code in HLD (VHDL or Verilog for example). Because of this, there are some restrictions: you cannot use "printf", "scanf", malloc and so on. For instance: how can you implement a printf in HLD upon an FPGA?
I recommend reading this tutorial and this user guide.
However, you can use "printf" ONLY in HLS simulation: at the end, you will not synthesize it. Here you can find the link to the discussion about this on Xilinx's forum.
You can update your question and add some more details in order to understand where the errors occur.

Does anyone know of any open source search projects written in Go?
I want to implement a simple site search for my site and am looking for a web crawler, but more specifically, a search algorithm written in Go.
Any ideas, projects, or suggestions?
For the web crawler part, there`s gocrawl: https://github.com/PuerkitoBio/gocrawl
Disclaimer: I'm the author.
You could try the suffixarray implementation in Go's standard library: http://golang.org/pkg/index/suffixarray/
Take a look at godoc how it can be used.

I just stumbled upon groovy++ and found it quite interesting.
Unfortunately it seems that it's not further developed?
According to github the last commit was over a year ago.
The mailing list is totally inactive and the last message was back in april.
There are no recent news about it.
Has the project moved and has another name now? Has it become obsolete because of improvements to groovy? Or is it just discontinued?
Thanks for any insight!
Groovypp stopped being updated about a year ago, and should be considered discontinued afaik.
Static compilation is now being added to Groovy 2.0 (via the #CompileStatic and #TypeChecked annotations).
There's some description of the new Groovy features here, and a performance comparison (for what it's worth) here
