2024-04-08 | Re: PR26978, Inconsistency for strong foo@v1 and weak foo@@v1 | Alan Modra | 1 | -2/+2 | |
Commit 726d7d1ecf opened a hole that allowed a u.i.link loop to be created, resulting in _bfd_generic_link_add_one_symbol never returning. Fix that. Note that the MIND case handles two types of redefinition. For a new indirect symbol we'll have string non-NULL. For a new def, string will be NULL. So moving the string comparison earlier would work. However, we've already looked up inh in the first case so can dispense with name comparisons. Either way, for a new def we'll get to the defweak test and possibly cycle. Which is what we want here. PR 31615 PR 26978 * linker.c (_bfd_generic_link_add_one_symbol <MIND>): Test for exactly matching indirect symbols before cycling on a defweak.

2024-04-03 | hppa: Implement PA 2.0 symbolic relocations for long displacements | John David Anglin | 1 | -1/+45 | |
The PA 2.0 architecture introduced several new load and store instructions with long displacements. These include floating point loads and stores for word mode, and integer and floating point loads and stores for double words. Currently, ld does not correctly support symbolic relocations for these instructions. If these are used, ld applies the standard R_PARISC_DPREL14R relocation and corrupts the instruction. This change uses bfd_hppa_insn2fmt to determine the correct relocation format. We need to check the computed displacement as the immediate value used in these instruction must be a multiple of 4 or 8 depending on whether the access is for a word or double word. A misaligned offset can potentially occur if the symbol is not properly aligned or if $global$ (the global pointer) is not double word aligned. $global$ is provided as a .data section start symbol. The patch adjusts elf.sc and hppalinux.sh to align .data to a 8-byte boundary in non-shared and non-pie links. 2024-04-01 John David Anglin <danglin@gcc.gnu.org> PR ld/31503 bfd/ChangeLog: * elf32-hppa.c (final_link_relocate): Output ld/ChangeLog: * emulparams/hppalinux.sh (DATA_SECTION_ALIGNMENT): Define. * scripttempl/elf.sc: Align .data section to DATA_SECTION_ALIGNMENT when relocating. | |||||
