Study Notes: Why xor eax, eax? Study Notes: Why xor eax, eax?

[ #Compiler ] Day 1 of #AoCO2025 Study Notes

While the original uses #CompilerExplorer, I wanted to replicate the analysis locally.

In this post, I have used #gcc, #clang, llvm-objdump and #LLDB to analyze.

HN discussed Compiler Explorer: how it works, surprisingly low costs, the 'Godbolt' vs 'Compiler Explorer' name debate, and future potential like WASM client-side compilation. Insights into infrastructure & ops appreciated. #CompilerExplorer 1/5

On my recent India visit, I gave multiple academic talks to 200+ CS students and 30+ faculty. Regrettably, I did not once use/mention Compiler Explorer. 🥺

The topics did not lend themselves to bringing up Compiler Explorer, but still I feel ungrateful, like I let down someone. 😳

[LIB REQUEST] JUnit for Java compiler and executor · Issue #6779 · compiler-explorer/compiler-explorer It will be super awesome if users can selectively include JUnit library when using Java compiler or executor. I don't know how hard it is to do this. 🤞

I was so hoping I could include JUnit with Java compiler/executor on Compiler Explorer, but alas. 😞

I don't know how hard it is to accomplish, but I filed a library request. Please vote and opine:

I filed a feature request for #CompilerExplorer
to "add executor" to "Conformance View" to make it easier to see results and save screen space.

As an educator, I know students mostly need/want to see execution results, not assembly.

Comments welcome. 🙏🏽

I tried #dlang's ctRegex (#cpp's #CTRE equivalent) in #compilerexplorer and it timeouts everytime after 30 seconds. I can't compare the assembly :(
