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 usual.) -- Joseph S. Myers joseph@codesourcery.com
