 202         obstack alignment.

 212         field of frchainS.  Don't create new frags on section switch, and

 214         section, set frchain_now to absolute_frchain.  Verify that
 215         frch_last and frag_now match on entry and exit.  Initialize
 216         per-chain obstack, and under gcc, set required alignment to that
 217         needed by fragS structure.

 223         (s_stab_generic): Cache stab section name to bypass lookups, since
 224         usually it will match.  Could be made faster still by changing the
 225         memory allocation rules.

 227         allocation.

 247
 248         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 249         frag_now_fix instead of accessing obstack info directly.

 336         * Makefile.in (comparison): Only check *.o; we don't care if
 337         timestamps inserted by the native linker differ.
 338
 339         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
 340         if alignment stricter than 4 bytes is requested; in that case,
 341         align to a 4-byte boundary first.

 351         qualifiers and detect errors if present.

 363         * config/tc-m68k.c (isword): Accept all values from -65536 to

 365
 366         * cond.c (s_endif): Call demand_empty_rest_of_line.  In MRI mode,
 367         skip characters after the pseudo-op.
