rfnixToday's been a fun ride down weird <a href="https://piaille.fr/tags/MSVC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MSVC</a> <a href="https://piaille.fr/tags/cpp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cpp</a> <a href="https://piaille.fr/tags/compiler" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#compiler</a> land, for some values of "fun".I'm still flabbergasted that it generates multiple SIMD rounds of packed doubles/singles conversions with a half full xmm register for a seemingly innocuous line of math and a call to std::exp2f. Like, why not use regular math instructions if you want to vectorize with N=1 width? Are these lines really "optimized"?

Chris BohnThis is some frackin' dark <a href="https://techhub.social/tags/compiler" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#compiler</a> magic. <a href="https://godbolt.org/z/6ans5YGnW" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://godbolt.org/z/6ans5YGnW</a>When I pay attention, I'm used to seeing `-Os` nibble at the edges to make the program's footprint smaller -- remove dead code, remove functions that don't get called, inline called-once functions, etc.I'm not surprised that it was able to achieve some amazing compression given the structure of the `switch` statements (and the pattern of values in the nested array) -- but wow. It replaced both 34-entry jump tables with a single 34-element array, and replaced the nested array with code to compute the array's elements. When I say it like that, it seems (as I said) not surprising, but it's still frickin' amazing.(For those wondering why I use this implementation instead of the commented-out simpler implementation, it's starter code for an assignment in which students need to scan a matrix keypad, replacing the library call -- giving them this in the starter code gets better results than giving them the simpler version in the starter code.)

Which violate open source paradigm.I was able to solve this in Gentoo GNU/Linux OS with reproducible way. First I compile Rust 1.74 version and then in chain I compile all versions to 1.84.All steps took approximately 8 hours, but after it is fast to compile new version, without blobs. 蠡

Brian SwetlandDusting off my little 32bit RISC ISA aimed at being extremely friendly for emulators and toolchains and human inspection.Unlike RISC-V the instruction encoding is tuned for software ease of implementation and understanding, not worrying about 16bit encodings, wider-than-32bit machines, etc.It does try to match RV32I in functionality so that if you generate these instructions but with the RV32 immediate width constraints, the mapping is almost always 1:1.<a href="https://chaos.social/tags/projects" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#projects</a> <a href="https://chaos.social/tags/compiler" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#compiler</a> <a href="https://chaos.social/tags/softrisc32" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#softrisc32</a>

Bread80Adding array definitions to the <a href="https://mstdn.social/tags/Quiche" class="mention hashtag" rel="tag">#Quiche</a> <a href="https://mstdn.social/tags/Compiler" class="mention hashtag" rel="tag">#Compiler</a>An array boils down to a bounds and an element type. For multidimensional arrays the 'inner' element type is itself an array definition.The parser for this works recursively which gives an elegantly simple solution (although the actual code is a little gnarly given the syntaxes). Parsing the bounds is parsing a type definition (of a suitable enumerable type). Parsing the element type means parsing another array definition.
