| 9 | |
| 10 | * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from |
| 11 | TC_FORCE_RELOCATION, taking an additional section argument. If |
| 12 | the section of the target symbol is not the same as the current |
| 13 | section, always force the relocation to be used. |
| 14 | (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section. |
| 15 | |
| 16 | * config/tc-ppc.c (md_pcrel_from_section): Rename from the |

| 21 | older TC_FORCE_RELOCATION if not defined. |
| 22 | (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from. |
| 23 | (fixup_segment): Use MD_PCREL_FROM_SECTION instead of |
| 24 | md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of |
| 25 | TC_FORCE_RELOCATION. |

| 27 | Mon Oct 23 16:20:04 1995 Ken Raeburn <raeburn@cygnus.com> |
| 28 | |
| 29 | * input-scrub.c (as_where): Set name to null pointer if we don't |
| 30 | have a file name. |
| 31 | * messages.c (identify): Only print filename if non-null. |
| 32 | (as_show_where): Ditto, for line number too. |
| 33 | (as_warn_internal, as_bad_internal): Ditto. |
| 34 | |
| 35 | * input-file.c (input_file_open): If the input file can't be |
| 36 | opened, consider it an error. |
| 37 | |
| 38 | Mon Oct 23 11:15:44 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk> |
| 39 | |
| 40 | * config/tc-mips.c: Added mips_4100 control, and support for |
| 41 | accepting the 4100 as a MIPS architecture variant (md_begin, |

| 44 | |
| 45 | Wed Oct 18 13:20:32 1995 Ken Raeburn <raeburn@cygnus.com> |
| 46 | |

| 48 | BFD_ASSEMBLER is defined. |
| 49 | |
| 50 | * Use one active frag and one obstack per frag chain: |
| 51 | * frags.c (frags): Variable deleted. |
| 52 | (frag_alloc): New function. |
| 53 | (frag_grow, frag_more, frag_variant, frag_now_fix, |
| 54 | frag_append_1_char): Refer to frchain_now->frch_obstack instead of |
| 55 | frags variable. |
| 56 | (frag_new): Ditto. Verify that frch_last and frag_now match on |
| 57 | entry and exit, and that old frag_now has non-zero type. Replace |
| 58 | "know" uses with "assert". Use frag_alloc instead of mucking with |
| 59 | obstack alignment. |
| 60 | * frags.h (frags): Declaration deleted. |
| 61 | * subsegs.h (struct frchain): Add new field frch_frag_now. |
| 62 | * subsegs.c (frchains, dummy_frag, absolute_frchain): New static |
| 63 | variables. |

| 65 | give it any stricter alignment than frchainS structures need. Do |
| 66 | not initialize frags obstack. Set frag_now to point to |
| 67 | dummy_obstack. Initialize absolute_frchain. |
| 68 | (subseg_set_rest): Save and restore frag_now in frch_frag_now |
| 69 | field of frchainS. Don't create new frags on section switch, and |
| 70 | use frag_alloc when creating a new frag chain. For absolute |
| 71 | section, set frchain_now to absolute_frchain. Verify that |
| 72 | frch_last and frag_now match on entry and exit. Initialize |
| 73 | per-chain obstack, and under gcc, set required alignment to that |
| 74 | needed by fragS structure. |
| 75 | |
| 76 | * write.c (chain_frchains_together_1): Verify fr_type is nonzero. |
| 77 | |
| 78 | * stabs.c (get_stab_string_offset): Only copy input string if a |
| 79 | fresh copy is needed, not if the section already exists. |
| 80 | (s_stab_generic): Cache stab section name to bypass lookups, since |
| 81 | usually it will match. Could be made faster still by changing the |
| 82 | memory allocation rules. |
| 83 | (s_xstab): Cache section name to bypass repeated string |
| 84 | allocation. |
| 85 | |
| 86 | * frags.c (frag_new): Deleted register declarations. |

| 95 | * read.c (read_begin): Use it. |
| 96 | |

| 99 | |
| 100 | * Makefile.in (distclean): Remove Makefile and config.status from |
| 101 | testsuite directory. |
| 102 | (clean-here): Don't delete testsuite. Instead, delete only the |
| 103 | files within it that would be generated by running tests. |
| 104 | |
| 105 | * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call |
| 106 | frag_now_fix instead of accessing obstack info directly. |
| 107 | * config/tc-arm.c (s_ltorg): Ditto. |
| 108 | (md_assemble): Ditto. |
| 109 | |
| 110 | * config/tc-i386.c (md_assemble): Call frag_grow instead of |
| 111 | obstack_room. |

| 113 | Wed Oct 18 12:22:59 1995 Ken Raeburn <raeburn@cygnus.com> |
| 114 | |
| 115 | * stabs.c (aout_process_stab): Insert debug symbol into symbol |
| 116 | chain after parsing value expression, if any, to avoid separating |
| 117 | continued .stabs lines. |
| 118 | |

| 127 | -mcom support and PPC_OPCODE_ANY for -many. |
| 128 | (md_parse_option): Ditto. |
| 129 | (ppc_arch): Ditto. |
| 130 | (md_begin): For duplicate instructions, print all duplicates |
| 131 | before aborting. |
| 132 | |
| 133 | Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com> |
