The -ma-step option enables compiler workarounds for A-step and B0-step
errata. So far it didn't seem worth the trouble to add a -mb0-step option.
This option will likely be removed before the next toolchain release.
There is also a -mb-step option that enables compiler workarounds for B-step
errata. This should be used if compiling code for B-step machines. -ma-step
implies -mb-step, so you don't need both.
For -mconstant-gp, see the discussion of the elf header flag EF_IA_64_CONS_GP
in the psABI.
