My patches from when I looked at this are available here: https://github.com/michaelforney/musl/compare/6a4f4a9...riscv Based on what you've already integrated into the `staging` branch, I think the only things left are related...

Also, I'm not sure if the merged fix for the `fcntl.h` issues is acceptable by upstream. See Rich Felker's recent comment on including `bits/*` headers from other headers: https://www.openwall.com/lists/musl/2019/02/12/7 `LONG_BIT`...

Looking at glibc's setjmp (https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/riscv/setjmp.S;h=38a93b78e88ec13535934394e1302a7ddbc12e8d;hb=HEAD#l46), I see they also use `__riscv_float_abi_soft`, so that gives me some confidence that this is the correct thing to check.

Unfortunately, I'm having trouble reproducing this. Here's what I tried - Using a fresh Debian sid image, I downloaded that llvm tarball and configured it with ``` cmake -G Ninja...
