* testsuite: prune DOS drive letter in test outputsClément Chigot2023-02-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | On DOS systems, absolute paths start with the drive letter. This can trigger failures in the regexp from dump tests, especially for those checking for warnings or errors. They are usually skipping everything before the first ":" as it has to be the file path. | [^:]*: warning: ...

* ld/testsuite: handle Windows drive letter in a noinit testClément Chigot2023-02-201-2/+2

* objdump -D of bss sections and -s with -jAlan Modra2023-02-1113-56/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ppc32 and "LOAD segment with RWX permissions"Alan Modra2023-02-061-0/+8
| | | | | | | | | | | | | | | | | | | | | 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.

* ld: pru: Merge the bss input sections into dataDimitar Dimitrov2023-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The popular method to load PRU firmware is through the remoteproc Linux kernel driver. In order to save a few bytes from the firmware, the PRU CRT0 is spared from calling memset for the bss segment [1]. Instead the host loader is supposed to zero out the bss segment. This is important for PRU, which typically has only 8KB for instruction memory. The legacy non-mainline PRU host driver relied on the default behaviour of the kernel core remoteproc [2]. That default is to zero out the loadable memory regions not backed by file storage (i.e. the bss sections). This worked for the libgloss' CRT0. But the PRU loader merged in mainline Linux explicitly changes the default behaviour [3]. It no longer is zeroing out memory regions. Hence the bss sections are not initialized - neither by CRT0, nor by the host loader. This patch fixes the issue by aligning the GNU LD default linker script with the mainline Linux kernel expectation. Since the mainline kernel driver is submitted by the PRU manufacturer itself (Text Instruments), we can consider that as defining the ABI. This change has been tested on Beaglebone AI-64 [4]. Static counter variables in the firmware are now always starting from zero, as expected. There was only one new toolchain test failure in orphan3.d, due to reordering of the output sections. I believe this is a harmless issue. I could not rewrite the PASS criteria to ignore the output section ordering, so I have disabled that test case for PRU.

* ld: Add pdb support to aarch64-w64-mingw32Mark Harmstone2023-01-2512-887/+888
| | | | | | | | | This extends PDB support to the aarch64 PE targets. The changes to the test files are just to make it so they can be assembled as either x86, x86_64, or aarch64, mainly by changing the comment style.

* Add support for secidx relocations to aarch64-w64-mingw32Mark Harmstone2023-01-232-0/+29
| | | | | | | | | | | | | This patch adds support for the .secidx directive and its corresponding relocation to aarch64-w64-mingw32. As with x86, this is a two-byte LE integer which gets filled in with the 1-based index of the output section that a symbol ends up in. This is needed for PDBs, which represent addresses as a .secrel32, .secidx pair. The test is substantially the same as for amd64, but with changes made for padding and alignment.

| | | | | | | | to check a situation that once failed with the new section merging when it mishandled offsets pointing into alignment padding in mergable string sections (i.e. pointing to zeros).

* arm32: Fix rodata-merge-mapMichael Matz2023-01-202-4/+4
| | | | | | | | | | | | the test expects a second, but useless, $d mapping symbol for the partially merged section, and specifically disallows one for the completely merged section. The new merging algorithm makes it so that also the partially merged sections are conceptually SEC_EXCLUDED, except the first merge section (e.g. as if the very first object file already contains all strings). So that second mapping symbol is now missing. It never was needed anyway. So, adjust the test.
