Hi Ali,<br /><br />For the process of compiling Windows on the ARM instruction set architecture it's about<br />instructing your compiler (e.g gcc or clang) to build your kernel code for the correct<br />CPU / hardware platform. There is no ARM toolchain per se, modern compilers can do well<br />cross-platform compilation (at least building on x86-64 and targeting ARM). Then it's<br />a bit of linker magic.<br /><br />About the usage of x86-specific assembly functions in the bitcoin core codebase, I think<br />there are some in the secp256k1 library about some scalar optimizations.<br /><br />That might interest you: https://groups.google.com/g/bitcoindev/c/fOIByS6COMk It's less<div>about compiling the whole machinery of bitcoin core itself and more focus on the libbitcoinkernel</div><div>engine, though including RISC-V support for the consensus engine compilation would be a</div><div>significant improvement, imho.<br /><br />Best,<br />Antoine<br />ots hash: d507461412e46e21156e9e2de5d65584c27d0cbca75d2e810f514fe8e077c9bd<br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">Le jeudi 21 novembre 2024 à 09:04:26 UTC, Ali Sherief a écrit :<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Apparently, there are only ARM binaries for Linux but not for Windows.<div><br></div><div>Considering that Apple Silicon is basically ARM as well, that means ARM binaries are produced for all the major operating systems except for Windows.</div><div><br></div><div>What would the process of compiling Windows with the ARM toolchain look like?
