|
|||
* config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
|
||||
also before setting STYP_NOLOAD for .bss section.
|
||||
|
||||
* config/tc-m68k.c (flag_reg_prefix_optional): New variable.
|
||||
Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
|
||||
zero.
|
||||
(m68k_reg_parse): If flag_reg_prefix_optional is set, permit
|
||||
register prefix to be absent.
|
||||
(m68k_ip_op): Accept `&' also for immediate constants.
|
||||
(insert_reg): Don't bother with (two!?) sanity checks of the
|
||||
symbol table when inserting each register.
|
||||
(m68k_parse_long_option): New function. Set
|
||||
flag_reg_prefix_optional if "register-prefix-optional" is passed.
|
||||
* config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
|
||||
defined.
|
||||
(OPTIONAL_REGISTER_PREFIX): Don't define.
|
||||
(REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
|
||||
or one depending on M68KCOFF.
|
||||
|
||||
Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
|
||||
* config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
|
||||
Define as macros instead of enumerators, since the Apollo compiler
|
||||
can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
|
||||
type.
|
||||
(make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
|
||||
(tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
|
||||
R_DIR16, and R_DIR32 relocs.
|
||||
* config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
|
||||
Use Apollo versions.
|
||||
[TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
|
||||
do include the optional header for Apollo target.
|
||||
(COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
|
||||
|
||||
* config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
|
||||
can be used within a label name.
|
||||
|
||||
* config/tc-m68k.h (m68k_init_after_args): Declare.
|
||||
(tc_init_after_args): Define as m68k_init_after_args.
|
||||
* config/tc-m68k.c (m68k_init_after_args): New function,
|
||||
containing one-shot code from md_assemble. Added warning for
|
||||
combination of 68040 and 68851.
|
||||
(md_assemble): Startup-time code deleted.
