The second one \nis to reduce the number of binaries qemu officially have. It does not \nimpact the number of targets, since 32-bit ones will still be supported.\n\nWe are currently working on Arm architecture with the first goal in \nmind. It does not bring anything useful in terms of feature, since \nqemu-system-aarch64 can already run anything that qemu-system-arm runs. \nHowever, it gives us a place to experiment and see how target code can \nefficiently and correctly modified to support the single-binary effort. \nWe know it's not yet the final word on this, because other architecture \nmakes more usage of target_ulong and TCGv, and we'll need another solution.\n\nEven if we create a plan to remove 32-bit targets when 64-bit ones \nsupport it, we will run into architectures that are an issue. Thus, I \nbelieve more strongly in refactoring the code, target after target. It \nwill take time, but thanks to the single-binary approach, we can \nprogress in iterations and in parallel, over years, and make sure there \nis no regression on files that have been ported.\n\nLet's fast forward 5 years in the future and imagine that all QEMU \ntargets are integrated in the single-binary. Once it is done, we know \nthat all files in target/X/* will be compiled only once, and integrated \nselectively for 32-bit or 64-bit targets. The key to understand is that \nin this setup, choosing to keep the 32-bit does not change anything. \nTechnically, it will just be a simple target-info file, representing \nthis 32-bit target, and a symlink for representing the target binary. \nAll the rest will already be common with 64-bit.\n\nWith this projection in mind, I wonder what is the concrete value to \nmake any proper plan to deprecate 32-bit targets, since in the end, it \nwon't matter if they are present or not.\n\nWhat are your thoughts?\nWhich value would we get from deprecating 32-bit targets when possible?\n\nRegards,\nPierrick","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=linaro.org header.i=@linaro.org header.a=rsa-sha256\n header.s=google header.b=JUgPlLVL;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=nongnu.org\n (client-ip=209.51.188.17;
