Does the pcsx-redux mipsel-none-elf gcc/clang toolchain support -std=c++26?

💡 Result:

Yes, the PCSX-Redux project supports and actively utilizes mipsel-none-elf GCC toolchains [1][2]. While the project often recommends or utilizes mipsel-linux-gnu toolchains for ease of installation on Linux distributions (such as via g++-mipsel-linux-gnu) [3][1], the documentation explicitly notes that if you are using a different MIPS compiler, such as mipsel-none-elf, you can override standard build variables to support it (e.g., PREFIX=mipsel-none-elf FORMAT=elf32-littlemips) [1][2]. Furthermore, the project provides specific resources to set up a mipsel-none-elf GCC toolchain, including: - Homebrew formulas for macOS to install mipsel-none-elf-gcc and mipsel-none-elf-binutils [4][5]. - A pre-compiled g++-mipsel-none-elf toolchain (version 10.3.0) for Windows users [1][2]. Regarding Clang, while GCC is the primary compiler used for the MIPS target, the project extensively uses Clang/LLVM for building the emulator itself [3][1] and integrates clangd within its recommended development workflow (Visual Studio Code) for code completion and navigation when developing PS1 applications with the PSYQo library [4].

mipsel G++ compiler support for C++26 standard flag c++26

💡 Result:

As of August 2, 2026, the G++ compiler provides experimental support for the C++26 standard, which is enabled using the command-line flag -std=c++26 [1][2]. This support is not tied to a specific CPU architecture like mipsel [3][4]. Because G++ is a cross-platform compiler, the -std=c++26 flag is available in any G++ version that implements these features, regardless of whether the target architecture is mipsel, x86_64, or others [1][3]. As of mid-2026, recent versions of the GCC toolchain (such as GCC 16.1) are available for the mipsel-linux-gnu architecture [3][4], and these versions include the -std=c++26 compiler option [1][2]. Please note the following: 1. Experimental Status: GCC's implementation of C++26 features is experimental [1][5]. The compiler may not maintain backward compatibility for features that did not reflect the final ISO standard [1]. 2. Availability: You can enable the standard using -std=c++26, or use -std=gnu++26 if you also require GNU-specific language extensions [1]. 3. Architecture Independence: The C++ standard flag is a feature of the GCC front-end (g++) and is generally consistent across all supported target architectures, provided your cross-compiler toolchain is updated to a version that supports the standard (GCC 14 or later) [1][3].

mips g++ c++26 -std=c++26 target support

💡 Result:

As of August 2, 2026, the GNU C++ compiler (g++) continues to provide robust target support for the MIPS architecture [1][2], while also implementing C++26 language and library features [3][4]. 1. C++26 Support: C++26 was officially published in March 2026 [3][4]. GCC 16.1, released in April 2026, provides extensive support for C++26 features, including stable support for reflection [3][4]. Compilers supporting the C++26 standard generally do so in a target-independent manner within the frontend (g++), meaning that if a specific C++26 feature is supported in GCC 16.1, it is available when targeting MIPS, provided the underlying toolchain version is sufficiently recent [3][4]. 2. MIPS Target Support: The GCC project maintains MIPS as a supported target architecture [5]. Modern GCC versions (including GCC 14 and 15, and continuing into the current GCC 16 era) include active support for various MIPS ISA variations (e.g., mips32r6, mips64r6) [2][5]. 3. How to Use: To use C++26 features when targeting MIPS, you must ensure your cross-compilation toolchain is based on a sufficiently recent version of GCC (e.g., GCC 16.1 or later) [4]. You can enable C++26 support by passing the standard flag to the compiler: -std=c++26 Since GCC support for C++ standards is primarily a property of the compiler frontend rather than the machine-specific backend, standard features are generally portable across all architectures supported by GCC, including MIPS, assuming the standard library implementation (such as libstdc++) is also updated to support the relevant C++26 library features [3].
