25 is PA2.0W code. Gcc generates PA1.1 code as the default for hppa-linux
and optionally will generate PA2.0 code. Thus, this only can occur if
a user writes his own PA2.0W assembler code. I have done a complete
bootstrap of gcc using binutils with the patch installed on hppa-linux.
There is no benefit in adding the 16 bit displacement insns to
elf32-hppa.c:final_link_relocate at the moment since the W bit
isn't on in userland.
Currently, the assembler ignores the "W" in .level directives under
asm.s: Assembler messages:
asm.s:1: Warning: rest of line ignored; first ignored character is `W'
Thus, it doesn't appear possible for mach to ever be 25 under hppa-linux.
