signed operand, sign extend a 32 bit value to the host size.
Permits dubious usage like
addi %r6,%r6,0xfffffeff
to assemble on a 64 bit host as it does on a 32 bit host.
(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.
Change OBJ_COFF checks to check OBJ_XCOFF instead.
(TARGET_FORMAT): Fully parenthesize.
(LEX_QM): Define if TE_PE.
* config/tc-ppc.c: Replace OBJ_COFF by OBJ_XCOFF throughout.
Remove checks of TE_PE within #ifdef OBJ_XCOFF sections.
(init_regtable): Make i unsigned.
(ppc_set_current_section): Rename from setCurrentSection. Change
all callers.
(ppc_arch): Return after as_fatal to avoid gcc warning.
(md_assemble): Only declare reloc if OBJ_ELF. Add default to
switch on fixups[i].reloc to avoid gcc warning.
(IMAGE_SGN_LNK_OTHER): Fix nested comment.
(ppc_pe_function): Don't call ppc_canonicalize_symbol_name.
(ppc_frob_symbol): Remove TE_PE section checks.
(md_estimate_size_before_relax): Return after abort to avoid gcc
warning.
(md_apply_fix3): Add BFD_RELOC_16_GOT_PCREL to switch.
* read.c (LEX_QM): Define as 0 if not defined.
(lex_type): Use LEX_QM for '?'.
