MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.
* as.h (struct frag, frag support): Moved from here.
* frags.h: To here.
(struct frag, member tc_frag_data): New member if TC_FRAG_TYPE
is defined.
(struct frag, member fr_cgen): Renamed from fr_targ.cgen.
* cgen.c (cgen_asm_finish_insn): Update.
* config/tc-m32r.c (md_estimate_size_before_relax): Update.
* config/tc-m32r.h (TC_FRAG_INIT): Renamed from md_init_frag.
(md_convert_frag): Ditto.
* config/tc-ns32k.h (TC_FRAG_TYPE): Define.
(frag_opcode_frag,frag_opcode_offset,frag_bsr): Update.
(TC_FRAG_INIT): Update.
* config/i386/cygwin32.mh: because cygwin.dll calls malloc/realloc
to allocate memory for environ space, gdb cannot use memory
checks -- set -DNO_MMCHECK
print out MD fields of fix.
* frags.c (frag_var, frag_variant): Use TC_FRAG_INIT macro (if
defined) to initialize MD fields in frag.
* as.h (struct frag, ns32k support): Rename ns32k to fr_ns32k.
Delete pcrel_adjust. Add fr_opcode_fragP, fr_opcode_offset.
* config/tc-ns32k.h: Add comments. Remove obsolete
BFD_FAST_SECTION_FILL definition, change prototypes for
fix_new_ns32k and fix_new_ns32k_exp to add new arguments
opcode_frag and opcode_offset and remove pcrel_adjust.
(TC_FIX_TYPE): add opcode_fragP and opcode_offset fields.
(TC_FIX_DATA_PRINT): new macro to print out TC_FIX_TYPE.
(TC_FRAG_INIT): new macro to initialize machine dependent field in
frags.
(frag_opcode_frag, frag_opcode_offset, frag_bsr): macros to access
MD fields in frag structure.
(fix_im_disp, fix_bit_fixP, fix_opcode_frag, fix_opcode_offset,
fix_bsr): macros to access MD fields in fix structure.
* config/tc-ns32k.c: Avoid overlength lines. Align comments. Don't
use struct opcode_location as these fields are now in the frag
structure.
(convert_iif): Call frag_more as it is needed instead
of trying to allocate for the whole insn. Avoid call of frag_more
with negative argument.
(md_pcrel_adjust, md_fix_pcrel_adjust, md_apply_fix,
md_estimate_size_before_relax, md_pcrel_from,
tc_aout_fix_to_chars): use accessor macros to get md fields in fix
and frag structures.
(fix_new_ns32k, fix_new_ns32k_exp): add new arguments opcode_frag and
opcode_offset and remove pcrel_adjust.
(convert_iif, cons_fix_new_ns32k): call fix_new_ns32k,
fix_new_ns32k_exp with changed arguments.
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write. This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
* sim-endian.c (sim_endian_split_16, sim_endian_join_16): New functions
* sim-endian.h (VL8_16, VH8_16): Implement.
* sim-memopt.c (memory_option_handler): Typecast 64bit value to long in printf.
(memory_option_handler): Only zalloc modulo bytes when non-zero.
(memory_option_handler): Skip comma in alias address list
that mips_cpu depends on TARGET_CPU, and mips_opts.isa depends on
mips_cpu.
(md_parse_option): Remove all code that sets defaults; md_begin
handles all of this now.
Check for `contents' flag. Give an error for unrecognized flags.
(copy_section): If the contents flag was set for a section that
had no contents, zero out the new contents.
* binutils.texi (objcopy): Document contents section flag.
PR 10601.
message instead of merely aborting.
* elf64-sparc.c (sparc64_elf_relocate_section): Likewise.
* elf64-sparc.c (sparc64_elf_check_relocs): Use SEC_ALLOC to control
whether we output dynamic relocs instead of SEC_DEBUGGING.
(sparc64_elf_relocate_section): Likewise.
(md_begin, md_parse_option): Handle 5400 options/names.
(macro_build, mips_ip): Check for 5400-specific instructions.
(md_longopts, OPTION_M5400, OPTION_NO_M5400): More command-line support for
5400.
* config/tc-mips.c (validate_mips_insn): New function, checks match versus mask
bits, and also verifies that all bits to be output are actually specified
somewhere.
(md_begin): Call it for 32-bit instructions, instead of doing match/mask check
here. In case of failure, print a message, but check the rest of the opcode
table before exiting.
that overlapping regions can be defined.
Allow the layer (level) of a memory region to be specified as part of
an address parameter to memory options.
Update simulators.
