You shouldn't have sqrt ulps.  This is long double, so different from the 
issue you addressed with commit cb756c6d686242acdc942e3d4276e399a69a6f02.  
I think you have a bug in your sfp-machine.h - its definition of 
FP_ROUNDMODE is expecting the low bits to be the rounding mode, which 
doesn't seem right for AArch64 - and need to fix that then regenerate the 
ulps from scratch again.  (That bug would also be user-visible in past 
releases, so should have a bug filed in Bugzilla when fixing it, as
