The problem is we don't have fstat() for LoongArch, and it'll be unusable on all 32-bit arch after 2037. And Arnd hates the idea adding fstat() for LoongArch because there would be one more 32-bit arch broken in 2037. Or should we just add something like "fstat_2037()"? -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
