-dbl_align_all=y

Force alignment of all data on 8-byte boundaries

SPARC:77 x86:77

y is either yes or no. If y is yes, all variables will be aligned on 8-byte boundaries. Default is -dbl_align_all=no.

When compiling for 64-bit environments with -xarch=v9 or v9a, this flag will align quad-precision data on 16-byte boundaries.

This flag does not alter the layout of data in COMMON blocks or user-defined structures.

On SPARC, use with -dalign to enable added efficiency with multi-word load/stores.

If used, all routines must be compiled with this flag.
