• [GSoC 2026] POC for the idea “Enable float80 and float128 math support on unsupported targets for LLVM libc” Hi everyone, To wrap my head around theEnable float80 and float128 math support on unsupported targets for LLVM libcGSoC project, I put together a quick proof of concept. • Since I’m on an ARM Mac, I wanted to see if I could get the libc math templates to instantiate without native__float128support. • I managed to get basic arithmetic passing the local test suite by integrating aUInt128-backed struct withFPBits. • Design Overview PoC Code I’d love some feedback!@lntue,@krishna2803and OverMighty, (I’m sorry I can tag only two) as the mentors for this idea, is this the right architectural direction? • Are there any immediate red flags or nits that you have? • Knowing what I need to rethink or fix will really help me perfect my formal proposal.

  • Hi everyone, To wrap my head around the Enable float80 and float128 math support on unsupported targets for LLVM libc GSoC project, I put together a quick proof of concept. Since I’m on an ARM Mac, I wanted to see if I could get the libc math templates to instantiate without native __float128 support. I managed to get basic arithmetic passing the local test suite by integrating a UInt128 -backed struct with FPBits . I’d love some feedback! @lntue, @krishna2803 and OverMighty, (I’m sorry I can tag only two) as the mentors for this idea, is this the right architectural direction? Are there any i
