Clément Chigot cd026728f3 gas: improve C_BSTAT and C_STSYM symbols handling on XCOFF ... A C_BSTAT debug symbol specifies the beginning of a static block. Its n_value is the index of the csect containing static symbols. A C_STSYM debug symbol represents the stabstring of a statically allocated symbol. Its n_value is the offset in the csect pointed by the containing C_BSTAT. These two special n_value were not correctly handled both when generating object files with gas or when reading them with objdump. This patch tries to improve that and, above all, to allow gas-generated object files with such symbols to be accepted by AIX ld. bfd/ * coff-bfd.c (bfd_coff_get_syment): Adjust n_value of symbols having fix_value = 1 in order to be an index and not a memory offset. * coffgen.c (coff_get_symbol_info): Likewize. (coff_print_symbol): Likewize. gas/ * config/tc-ppc.c (ppc_frob_label): Don't change within if already set. (ppc_stabx): Remove workaround changing exp.X_add_symbol's within. * config/tc-ppc.h (struct ppc_tc_sy): Update comments. * symbols.c (resolve_symbol_value): Remove symbol update when final_val is 0 and it's an AIX debug symbol. * testsuite/gas/ppc/aix.exp: Add new tests. * testsuite/gas/ppc/xcoff-stsym-32.d: New test. * testsuite/gas/ppc/xcoff-stsym-64.d: New test. * testsuite/gas/ppc/xcoff-stsym.s: New test.		2021-07-29 10:55:22 +02:00
