2022-11-30section-select: Fix exclude-file-3Michael Matz1-1/+3
this testcase wasn't correctly testing everything, it passed, even though sections from an excluded file were included. Fixing this reveals a problem in the new section selector. This fixes that as well.
2022-11-28Only use wild_sort_fastMichael Matz4-0/+36
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).

2022-01-05elf: Set p_align to the minimum page size if possibleH.J. Lu2-2/+2
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.

2021-09-03CC_FOR_TARGET et alAlan Modra1-20/+20
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.

2021-03-10bfd: strip symbols not representable in COFF/PE symbol tableJan Beulich2-3/+2
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.
2021-03-09bfd: don't silently wrap or truncate PE image section RVAsJan Beulich10-12/+35
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 39a7b38fac0e ("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.
2021-03-04ld: adjust ld-scripts/map-address.*Jan Beulich2-4/+13
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.

2021-02-14ld testsuite: change unresolved to unsupported/failAlan Modra13-32/+17
"unresolved" as a test result means runtest returns an error, which can be confusing when there is no apparent error unless you look in .log files. In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved.

2020-10-16ld: Allow symbols from PROVIDE to be use in MEMORY regionsAndrew Burgess9-0/+61
I wanted to write a linker script like this: PROVIDE(mem_origin = 0x1000); PROVIDE(mem_length = 0x1000); MEMORY { REGION : ORIGIN = mem_origin, LENGTH = mem_length } .... Then when I link using this script I can optionally supply: --defsym=mem_origin=..... --defsym=mem_length=.... to override the defaults. And though passing `--defsym' does work, if I remove the use of `--defsym' and just rely on the defaults I get an error: ld-new: invalid origin for memory region REGION Interestingly, if I make the above error non-fatal and dump a linker map file I see that (a) REGION has origin 0x0, and length 0xffff..., and (b) the symbol from the PROVIDE is provided. An examination of ldlang.c:lang_process shows us what the issue is, the origin and length of all memory regions are set as a result of a single call to lang_do_memory_regions, this call is done after calling open_input_bfds. During the open_input_bfds call provide statements can be converted to provided statements if we know that the assigned symbol is needed, but for symbols that are only used in the memory regions we are unaware that we need these symbols. What I propose in this patch is to make two calls to lang_do_memory_regions, in the first call we process the expressions for the origin and length fields of each region, however, errors, especially undefined symbols, will be ignored. The origin and length values are not updated. However, by evaluating the expressions any symbols we need will be added to the symbol table. Now when we call open_input_bfds, when we process the provide statements, we will see that the assigned symbol is needed add its new value to the symbol table. Finally we reach the original call to lang_do_memory_regions, in this (now second) call we again process the expressions, and this time update the origin and length values. Any errors encountered now are reported to the user. ld/ChangeLog: * ldlang.c (lang_process): Add extra call to lang_do_memory_regions, and pass parameter. (lang_do_memory_regions): Add parameter, only define origin and length when requested.

2020-06-20Remove perror from ld_assemble, ld_compile and ld_nmAlan Modra6-34/+27
ERROR should really be reserved for errors in the testsuite framework, not just normal errors from the tools under test. Removing use of perror has been suggested before but without action, over concerns that some test failures might be missed. This patch removes uses of perror in ld_assemble, ld_compile and ld_nm, and updates numerous places that ignored the result of these functions by inappropriately returning an "unresolved" test status. Net result over my large set of targets look good, in some cases improving the diagnostics, eg: i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos +FAIL: script i386-msdos +FAIL: MRI script i386-msdos +FAIL: MEMORY i386-msdos +FAIL: MEMORY with symbols * testsuite/lib/ld-lib.exp (default_ld_compile): Don't perror on a compiler error.
