$extend. Based on code from Eric Freudenthal
<freudenthal@nyu.edu>.
* config/tc-a29k.h (LEX_DOLLAR): Define.
* read.c (LEX_DOLLAR): Define if not defined.
(lex_type): Use LEX_DOLLAR.
set to 1.
* macro.c (get_any_string): Don't keep quotes if macro_strip_at is
set, even if macro_alternate is set.
(get_apost_token): If macro_strip_at, only skip kind if it is '@'.
(sub_actual): If macro_strip_at, and kind is '@', don't look up
the token unless it ended in '@'.
* config/tc-a29k.c (line_separator_chars): Remove '@'.
* doc/c-a29k.texi: Document macro usage on A29K.
(ppc_eb): Likewise. Set the storage class to C_BLOCK, not C_FCN.
(ppc_frob_symbol): Don't change C_BLOCK symbols to C_HIDEXT.
* config/obj-coff.c (coff_frob_symbol): Don't call
SA_SET_SYM_ENDNDX with the current symbol; call it with the next
one. If OBJ_XCOFF, try to figure out whether the symbol is going
to be dropped.
(ppc_stab_symbol): New static variable.
(ppc_change_csect): Check that ppc_toc_csect is not NULL.
(ppc_stabx): Set ppc_stab_symbol around call to symbol_make. Set
sy_tc.real_name to the stab string.
(ppc_bc, ppc_ec): New static functions.
(ppc_canonicalize_symbol_name): If ppc_stab_symbol is set, don't
do anything.
(ppc_symbol_new_hook): If ppc_stab_symbol is set, don't look for a
suffix.
(ppc_csect): Move most of the code to ppc_change_csect, and call
it.
(ppc_change_csect): New static function, taken from ppc_csect.
(ppc_section): New static function.
(ppc_saw_abs): New static varable.
(ppc_frob_symbol): Create aux entry for absolute symbols. Warn if
a symbol has no csect.
(ppc_adjust_symtab): New function.
* config/tc-ppc.h (tc_adjust_symtab): Define if OBJ_XCOFF.
(ppc_adjust_symtab): Declare if OBJ_XCOFF.
(pa_subspace): For ".nsubspa", always create a new subspace
with the given attributes, even if one already exists with the
same name.
So we can put every function into its own $CODE$ subspace.
* frags.c (frags): Variable deleted.
(frag_alloc): New function.
(frag_grow, frag_more, frag_variant, frag_now_fix, frag_append_1_char): Refer
to frchain_now->frch_obstack instead of frags variable.
(frag_new): Ditto. Verify that frch_last and frag_now match on entry and exit,
and that old frag_now has non-zero type. Replace "know" uses with "assert".
Use frag_alloc instead of mucking with obstack alignment.
* frags.h (frags): Declaration deleted.
* subsegs.h (struct frchain): Add new field frch_frag_now.
* subsegs.c (frchains, dummy_frag, absolute_frchain): New static variables.
(subsegs_begin): Initialize frchains obstack. Under gcc, don't give it any
stricter alignment than frchainS structures need. Do not initialize frags
obstack. Set frag_now to point to dummy_obstack. Initialize absolute_frchain.
(subseg_set_rest): Save and restore frag_now in frch_frag_now field of
frchainS. Don't create new frags on section switch, and use frag_alloc when
creating a new frag chain. For absolute section, set frchain_now to
absolute_frchain. Verify that frch_last and frag_now match on entry and exit.
Initialize per-chain obstack, and under gcc, set required alignment to that
needed by fragS structure.
* write.c (chain_frchains_together_1): Verify fr_type is nonzero.
In one test case of Mike's (i386-linux, over 300K lines of .s code with lots
of stabs records), run time and memory use are reduced by about 1/3.
Might introduce some problems in cases that use the frag obstacks in unusual
ways. Test suite does pass for i386-linux and sparc-solaris targets though.
