From a4dd6c97bd5c7e2cc58f4d2a0b83145646f67cc7 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 2 Mar 2020 10:17:18 +1030 Subject: miscellaneous SEC_SMALL_DATA This patch arranges for symbols defined in .sdata and .sbss to be reported by nm with 'g' and 's' flags, for coff targets that support .sdata and .sbss. The assembler changes regarding SEC_SMALL_DATA are really just documentation. As far as I'm aware, this won't change any assembler output. bfd/ * coff-alpha.c (alpha_ecoff_le_vec): Add SEC_SMALL_DATA to applicable section flags. * coff-mips.c (mips_ecoff_le_vec, mips_ecoff_be_vec): Likewise. (mips_ecoff_bele_vec): Likewise. * coffcode.h (sec_to_styp_flags): Set SEC_SMALL_DATA for .sdata and .sbss sections. * ecoff.c (_bfd_ecoff_new_section_hook): Likewise. (_bfd_ecoff_styp_to_sec_flags): Likewise. gas/ * config/tc-m32r.c (md_begin): Set SEC_SMALL_DATA on .scommon section. * config/tc-mips.c (s_change_sec): Set SEC_SMALL_DATA for .sdata and .sbss sections. * config/tc-score.c: Delete !BFD_ASSEMBLER code throughout. (s3_s_change_sec): Set SEC_SMALL_DATA for .sbss section. (s3_s_score_lcomm): Likewise. * config/tc-score7.c: Similarly. * read.c (bss_alloc): Set SEC_SMALL_DATA for .sbss section. --- bfd/ecoff.c | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-) (limited to 'bfd/ecoff.c') diff --git a/bfd/ecoff.c b/bfd/ecoff.c index 9e2efac..84eab99 100644 --- a/bfd/ecoff.c +++ b/bfd/ecoff.c @@ -156,14 +156,14 @@ _bfd_ecoff_new_section_hook (bfd *abfd, asection *section) { _INIT, SEC_ALLOC | SEC_CODE | SEC_LOAD }, { _FINI, SEC_ALLOC | SEC_CODE | SEC_LOAD }, { _DATA, SEC_ALLOC | SEC_DATA | SEC_LOAD }, - { _SDATA, SEC_ALLOC | SEC_DATA | SEC_LOAD }, + { _SDATA, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_SMALL_DATA }, { _RDATA, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY}, - { _LIT8, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY}, - { _LIT4, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY}, + { _LIT8, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY | SEC_SMALL_DATA}, + { _LIT4, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY | SEC_SMALL_DATA}, { _RCONST, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY}, { _PDATA, SEC_ALLOC | SEC_DATA | SEC_LOAD | SEC_READONLY}, { _BSS, SEC_ALLOC}, - { _SBSS, SEC_ALLOC}, + { _SBSS, SEC_ALLOC | SEC_SMALL_DATA}, /* An Irix 4 shared libary. */ { _LIB, SEC_COFF_SHARED_LIBRARY} }; @@ -412,16 +412,19 @@ _bfd_ecoff_styp_to_sec_flags (bfd *abfd ATTRIBUTE_UNUSED, || styp_flags == STYP_PDATA || styp_flags == STYP_RCONST) sec_flags |= SEC_READONLY; + if (styp_flags & STYP_SDATA) + sec_flags |= SEC_SMALL_DATA; } - else if ((styp_flags & STYP_BSS) - || (styp_flags & STYP_SBSS)) + else if (styp_flags & STYP_SBSS) + sec_flags |= SEC_ALLOC | SEC_SMALL_DATA; + else if (styp_flags & STYP_BSS) sec_flags |= SEC_ALLOC; else if ((styp_flags & STYP_INFO) || styp_flags == STYP_COMMENT) sec_flags |= SEC_NEVER_LOAD; else if ((styp_flags & STYP_LITA) || (styp_flags & STYP_LIT8) || (styp_flags & STYP_LIT4)) - sec_flags |= SEC_DATA | SEC_LOAD | SEC_ALLOC | SEC_READONLY; + sec_flags |= SEC_DATA |SEC_SMALL_DATA | SEC_LOAD | SEC_ALLOC | SEC_READONLY; else if (styp_flags & STYP_ECOFF_LIB) sec_flags |= SEC_COFF_SHARED_LIBRARY; else -- cgit v1.1
