* ld/testsuite: disable ilp32 tests for aarch64-qnxClément Chigot2023-03-1639-0/+39

* ld: add support of QNX stack arguments for aarch64ntoClément Chigot2023-03-166-1/+220
| | | | | | | | | | | | | | | | | | | QNX is handling the stack argument using a .note section. Generate it according to ELF argument -zexecstack, -zstack-size and a new NTO argument --lazy-stack. Another NTO argument --stack mimicking -zstack-size is added in order to ensure compatibility with previously made NTO linkers. This requires a new emultempl nto.em which is applied above the default ${ARCH}elf.em. ld/ChangeLog: * emulparams/aarch64nto.sh: Move to nto.em. * emultempl/nto.em: New file. * testsuite/ld-aarch64/aarch64-nto.exp: New test. * testsuite/ld-aarch64/nto-stack-note-1.d: New test. * testsuite/ld-aarch64/nto-stack-note-2.d: New test. * testsuite/ld-aarch64/start.s: New test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

* RISC-V: Reduce effective linker relaxation passsesTsukasa OI2023-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | Commit 43025f01a0c9 ("RISC-V: Improve link time complexity.") reduced the time complexity of the linker relaxation but some code portions did not reflect this change. This commit fixes a comment describing each relaxation pass and reduces actual number of passes for the RISC-V linker relaxation from 3 to 2. 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.
* ppc32 and "LOAD segment with RWX permissions"Alan Modra2023-02-062-0/+10
| | | | | | | | | | | | | | | | | | | | | 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: Add optional section alignmentsDimitar Dimitrov2023-02-041-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Texas Instruments SoCs with AARCH64 host processors have stricter alignment requirements than ones with ARM32 host processors. It's not only the requirement for resource_table to be aligned to 8. But also any loadable segment size must be a multiple of 4 [1]. The current PRU default linker script may output a segment size not aligned to 4, which would cause firmware load failure on AARCH64 hosts. Fix this by using COMMONPAGESIZE and MAXPAGESIZE to signify respectively the section memory size requirement and the resource table section's start address alignment. This would avoid penalizing the ARM32 hosts, for which the default values (1 and 1) are sufficient. For AARCH64 hosts, the alignments would be overwritten from GCC spec files using the linker command line, e.g.: -z common-page-size=4 -z max-page-size=8 [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/remoteproc/pru_rproc.c?h=v6.1#n555 ld/ChangeLog: * scripttempl/pru.sc (_data_end): Remove the alignment.

* ld: pru: Merge the bss input sections into dataDimitar Dimitrov2023-02-042-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
