Are NEON intrinsics the > problem? OK, Neon is almost certainly your problem. It should never be used as the default for a toolchain because it produces non-IEEE-conforming results. You can enable Neon for individual applications where you don't care (just like -ffast-math) but using it to build libc will result in a broken libc, and using it by default could break other apps too. Perhaps we should add something to musl's configure to detect this misconfiguration and error out or disable Neon? Rich ^ permalink raw reply [flat|nested] 9+ messages in thread

It should never be used as --with-fpu=neon-fp16 should just mean that neon and 16bit fp are available (as extensions to vfp), it does not mean neon arithmetics is used by default (and even if it were the failures are not explained) there is some fundamental problem with the toolchain/qemu/.. and i dont yet see what.. e.g. wrong float.h was used or similarly bad thing. > the default for a toolchain because it produces non-IEEE-conforming > results.
