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. |
