* elf32-v850.c (all functions and static variables): Go through
|
||||
and regularize names to be of the form v850_elf_<xxx>.
|
||||
(toplevel): Include <elf/v850.h>.
|
||||
(enum reloc_type): Move to include/elf/v850.h.
|
||||
(v850_elf_check_relocs): For common variables, if the variable is
|
||||
referenced by a R_V850_{SDA,ZDA,TDA} relocation, put the variable
|
||||
into the appropriate section.
|
||||
(elf_backend_check_relocs): Define.
