Added facility + for keeping or rejecting configurations still under development; + default is to assume production environment, and reject configs + still being worked on. Mark Elf configurations (except sparc and + i386) as developmental. Deleted cases matching some generic names + in favor of more specific names. (E.g., when we get Alpha + support, we'll still only support VMS for Vax.) + + * config/tc-sparc.h (md_end): New macro. + * config/tc-sparc.c (md_end): Function deleted. + (BFD_RELOC_*): Delete macros that used to help keep the non-bfd + version compiling.

Use GNU-style comments. Warn + against placing additional object-file dependent code here. Warn + against contaminating all of GAS with the internals of tc-hppa.c + through inclusion of tc-hppa.h. Delete all forward declarations + for functions only used within tc-hppa.c, likewise for structures, + variables, and #defines. Try to group OBJ_ELF and OBJ_SOM + conditional code in a few small places. + + * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group + structures, global variables, forward declarations together. + Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM + conditional code -- try to group conditional code together + into a few places. Make all functions and variables which + are only used within tc-hppa.c static. PARAMize all functions. + Add comments to functions. Delete unused functions, variables, + #defines, etc. Delete unused members within structures. Delete + ldil;ble hacks -- it is believed they were installed to work + around old gas bugs. Avoid using mixed case for local + functions, variables, and structures. Fix formatting problems + not found by GNU-indent. Add FIXME notices for things which + should be worked on the near future. Delete lots of old + useless (1.36 PA-SOM) code. + + * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type + field of the fixS structure. Needed to build unwind + descriptors correctly. + + * write.c: (fixup_segment): Allow expressions such as + sym1-sym2+const as long as sym2 is $global$. + + * write.c (adjust_reloc_syms): Provide a hook so that a target + cpu configuration can reject certain relocation reductions. + * tc-hppa.h (tc_fix_adjustable): New macro. Only accept relocations + which do not involve function symbols. + + * config/tc-hppa.h: Reindent with GNU-indent. Delete references + to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused + STAB_FIXUP macro. + * config/tc-hppa.c: Likewise. + + * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead + of elf32_symbol_type. + (pa_export_args): Likewise. + (elf_hppa_final_processing): Likewise. + (pa_desc): Do not call obj_elf_desc.
