Christophe Lyon	b7571e1e6f	Re: Add --enable-linker-version option The recently-added ld-version.d tests expect .GNU ld $GNU Binutils$ 2.* in the .comment section. However, when buidling --with-pkgversion=XXX, we get GNU ld (XXX) 2.[...] instead, leading to a spurious FAIL. This small patch replaces "GNU Binutils" with ".*" instead. I inspected other testcases to see if we already had similar occurrences but I couldn't see any, so I hope this fix is OK for the purpose? Thanks, Christophe	3 years ago

Alan Modra	6752dd75f7	Re: Add --enable-linker-verssion Output sections without any input sections to initialise their flags have their flags initialised by data statements to LOAD, ALLOC, HAS_CONTENTS by default. This is wrong for .comment. Fix that by making the script initialise the section type to INFO, one of the noalloc section types.

Alan Modra	0a3137ce4c	objdump -D of bss sections and -s with -j There is some inconsistency between the behaviour of objdump -D and objdump -s, both supposedly operating on all sections by default. objdump -s ignores bss sections, while objdump -D dissassembles the zeros. Fix this by making objdump -D ignore bss sections too. Furthermore, "objdump -s -j .bss" doesn't dump .bss as it should, since the user is specifically asking to look at all those zeros. This change does find some tests that used objdump -D with expected output in bss-style sections. I've updated all the msp430 tests that just wanted to find a non-empty section to look at section headers instead, making the tests slightly more stringent. The ppc xcoff and spu tests are fixed by adding -j options to objdump, which makes the tests somewhat more lenient. binutils/ * objdump.c (disassemble_section): Ignore sections without contents, unless overridden by -j.

Though it does not change the functionality, it marginally improves the performance while linking large programs (with many relocations). bfd/ChangeLog: * elfnn-riscv.c (_bfd_riscv_relax_section): Fix a comment to reflect current roles of each relaxation pass. ld/ChangeLog: * emultempl/riscvelf.em: Reduce the number of linker relaxation passes from 3 to 2.	4 years ago
Alan Modra	8478900290	ppc32 and "LOAD segment with RWX permissions" When using a bss-plt we'll always trigger the RWX warning, which disturbs gcc test results. On the other hand, there may be reason to want the warning when gcc is configured with --enable-secureplt. So turning off the warning entirely for powerpc might not be the best solution. Instead, we'll turn off the warning whenever a bss-plt is generated, unless the user explicitly asked for the warning. bfd/ * elf32-ppc.c (ppc_elf_select_plt_layout): Set no_warn_rwx_segments on generating a bss plt, unless explicity enabled by the user. Also show the bss-plt warning when --warn-rwx-segments is given without --bss-plt. include/ * bfdlink.h (struct bfd_link_info): Add user_warn_rwx_segments. ld/ * lexsup.c (parse_args): Set user_warn_rwx_segments. * testsuite/ld-elf/elf.exp: Pass --secure-plt for powerpc to the rwx tests.	4 years ago
