--- Comment #53 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by John David Anglin <dang...@gcc.gnu.org>: https://gcc.gnu.org/g:f0fda1aff0b752e4182c009c5526b9306bd35f7c commit r14-9511-gf0fda1aff0b752e4182c009c5526b9306bd35f7c Author: John David Anglin <dang...@gcc.gnu.org> Date: Mon Mar 18 00:19:36 2024 +0000 hppa: Improve handling of REG+D addresses when generating PA 2.0 code In looking at PR 112415, it became clear that improvements could be made in the handling of loads and stores using REG+D addresses. A change in 2002 conflated two issues: 1) We can't generate insns with 14-bit displacements before reload completes when generating PA 1.x code since floating-point loads and stores only support 5-bit offsets in PA 1.x. 2) The GNU ELF 32-bit linker lacks relocation support for PA 2.0 floating point instructions with 14-bit displacements. These relocations affect instructions with symbolic references. The result of the change was to block creation of PA 2.0 instructions with 14-bit REG_D displacements for SImode, DImode, SFmode and DFmode on the GNU linux target before reload. This was unnecessary as these instructions don't need relocation. This change revises the INT14_OK_STRICT define to allow creation of instructions with 14-bit REG+D addresses before reload when generating PA 2.0 code. 2024-03-17 John David Anglin <dang...@gcc.gnu.org> gcc/ChangeLog: PR rtl-optimization/112415 * config/pa/pa.cc (pa_emit_move_sequence): Revise condition for symbolic memory operands.
