|

* config/alphaosf.mh (HDEFINES): Don't define HOST_64_BIT here;
|
||||
that's dealt with elsewhere.
|
||||
* hosts/alphaosf.h (sprintf_vma, fprintf_vma): New macros.
|
||||
(uint64_typeHIGH, uint64_typeLOW): Comment with HOST_64_BIT so
|
||||
they get copied to bfd.h.
|
||||
|
||||
* reloc.c (enum bfd_reloc_code_real): Add some Alpha relocation
|
||||
types. Reorganized some of the existing ones.
|
||||
* coff-alpha.c (alpha_howto_table): Construct 64-bit negative one
|
||||
values in case of compilation on a 32-bit machine. Fix pcrel
|
||||
fields of some reloc types.
|
||||
(alpha_bfd_reloc_type_lookup): Handle more relocation types.
|
||||
|
||||
* bfd-in.h (uint64_typeHIGH, uint64_typeLOW): Supply default
|
||||
definitions when not defined, regardless of whether uint64_type is
|
||||
a defined macro or not.
|
||||
(fprintf_vma, sprintf_vma): Define only if fprintf_vma is not
|
||||
already defined.
