[Qemu-devel] [PATCH 0/2] linux-user/mips: Support the n32 ABI for the R5900

[Fredrik Noring <noring@nocrew.org>]

Recognise the R5900, which reports itself as MIPS III, as a 64-bit CPU
supporting the n32 ABI. Test that DMULT is emulated in user mode.

This series has been successfully built with the 10 different build
configurations

    {gcc,clang} x -m64 x mips{,64}el-{linux-user,softmmu}
    {gcc,clang} x -m64 x mipsn32el-linux-user

in addition successfully completing the R5900 test suite

    cd tests/tcg/mips/mipsr5900 && make check
    cd tests/tcg/mips/mipsn32r5900 && make check
