Alan Modra	4b72a278f4	PR23881, pdp11 binutils fails if too much debug data The PR testcase overflows one of the exec header fields, e_syms (the size of the symbol table), leading to the string table offset being wrong. Things go downhill from there. Fixed by checking for overflow. This happens to trigger in the ld testsuite, so xfail that test. PR 23881 bfd/ * libaout.h (swap_exec_header_out): Return a bool. * aoutx.h (swap_exec_header_out): Check for overflow in exec header. * pdp11.c (swap_exec_header_out): Likewise. * i386lynx.c (WRITE_HEADERS): Adjust. ld/ * testsuite/ld-scripts/map-address.exp: xfail pdp11.	2 years ago
Alan Modra	fd67aa1129	Update year range in copyright notice of binutils files Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out /po/.pot which we don't update frequently.	3 years ago

Alan Modra	0749c73cf8	Re: Add some expected failures for bfin linker tests After commit `7ade0f1582` I was seeing bfin-elf +XPASS: weak symbols, and on looking into the bfin targets a little, discovered we have two bfin-linux targets. One, bfin-uclinux, is like bfin-elf in that ld -m elf32bfin is the default, and the other, bfin-linux-uclibc where ld -m elf32bfinfd is the default. So putting bfin--linux* in test xfails or elsewhere is wrong. We want bfin--linux instead to just select the fdpic bfin target. This patch corrects wrong bfin target triples in the ld testsuite, not just the recent change but others I'd added to xfails too. It also fixes the bfin-linux-uclibc ld-elf/64ksec fail	3 years ago

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. That also allows the address of .comment to be set to zero, as is usual for non-alloc sections. Also, use source_sh for all of the sourced scripts to set up make dependencies.

Michael Matz	af31506c31	Only use wild_sort_fast there's no reason why the tree-based variant can't always be used when sorting is required, it merely needs to also support filename sorting and have a fast path for insertion at end (aka rightmost tree leaf). The filename sorting isn't tested anywhere and the only scripttempl that uses it is avr (for 'SORT(*)(.ctors)'), and I believe even there it was a mistake. Either way, this adds a testcase for filename sorting as well. Then the non-BST based sorting can be simplified to only support the fast case of no sorting required at all (at the same time renaming the two variants to _sort and _nosort).	4 years ago

H.J. Lu	74e315dbfe	elf: Set p_align to the minimum page size if possible Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align values of 0x10000 even if no section alignment is greater than 0x1000. The issue is more general and probably affects other targets with multiple page sizes. While file layout absolutely must take 64K page size into account, that does not have to be reflected in the p_align value. If running on a 64K kernel, the file will be loaded at a 64K page boundary by necessity. On a 4K kernel, 64K alignment is not needed. The glibc loader has been fixed to honor p_align: https://sourceware.org/bugzilla/show_bug.cgi?id=28676 similar to kernel: commit ce81bb256a224259ab686742a6284930cbe4f1fa Author: Chris Kennelly <ckennelly@google.com> Date: Thu Oct 15 20:12:32 2020 -0700 fs/binfmt_elf: use PT_LOAD p_align values for suitable start address This means that on 4K kernels, we will start to do extra work for 64K p_align, but this pointless for pretty much all binaries (whose section alignment rarely exceeds 16). The minimum page size is used, instead of the maximum section alignment due to this glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28688 It has been fixed in glibc 2.35. But linker output must work on existing glibc binaries. 1. Set p_align to the minimum page size while laying out segments aligning to the maximum page size or section alignment. The run-time loader can align segments to the minimum page size or above, depending on system page size. 2. If -z max-page-size=NNN is used, p_align will be set to the maximum page size or the largest section alignment. 3. If a section requires alignment higher than the minimum page size, don't set p_align to the minimum page size. 4. If a section requires alignment higher than the maximum page size, set p_align to the section alignment. 5. For objcopy, when the minimum page size != the maximum page size, p_align may be set to the minimum page size while segments are aligned to the maximum page size. In this case, the input p_align will be ignored and the maximum page size will be used to align the ouput segments. 6. Update linker to disallow the common page size > the maximum page size. 7. Update linker to avoid the common page size > the maximum page size. 8.

Alan Modra	ad77db1c02	CC_FOR_TARGET et al The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will correct bootstrap.exp to use CFLAGS, and a number of other things I noticed. binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Use CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS. ld/ * Makefile.am (check-DEJAGNU): Don't set CC to CC_FOR_TARGET and similar.

Jan Beulich	67b0f68480	bfd: strip symbols not representable in COFF/PE symbol table The offset-within-section field in the symbol table entry is only 32 bits wide, so rather than emitting bogus entries omit them, and issue a diagnostic identifying the issue. This requires adjusting the PR/22267 test to no longer produce symbols with out of range values on 64-bit BFD. This also depends on adjustments to testsuite/ld-scripts/map-address.* made by an earlier patch. The purpose of the test can very well be achieved nevertheless.	5 years ago
Jan Beulich	87fa7d568d	bfd: don't silently wrap or truncate PE image section RVAs In PE images section addresses get expressed as addresses relative to the image base. Therefore the VA of a section must be no less than the image base, and after subtraction of the image base the resulting value should fit in 32 bits. (The issue is particularly obvious to notice when sections, perhaps because of ELF assumptions, get placed at VA 0 by default. Debugging info sections as well as .comment, when input files are ELF, are a good example. All such sections need proper mentioning in the linker script to avoid this warning.) There are a number of test cases which previously produced bogus images, yet still declared the test a success. Like done for other tests already, force a zero image base for these. This then also allows (and requires) dropping again xfail-s which `39a7b38fac` ("Fix linker tests to work with 16-bit targets") had added to ld-scripts/default-script.d (originally as skip-s). This also depends on similar adjustments to testsuite/ld-scripts/map-address. made by an earlier patch. For ld-scripts/print-memory-usage.* I suppose xcoff could be dropped from the exclusion list by suppressing garbage collection, just like already done in e.g. (as seen in the diff here) ld-scripts/data.*, but I didn't want to make unrelated adjustments.	5 years ago
Jan Beulich	d4e5db4e50	ld: adjust ld-scripts/map-address.* Without setting an image base address and without naming at least .text, this test produces entirely bogus PE output. To be honest, even the ELF output looks odd: .text gets placed at 0x10204, and both foo and bar get associated with .text despite living below its start address. Since neither image base nor .text placement are the subject of this test, specify .text placement explicitly and in the PE case force the image base to zero.	6 years ago
