bfd/ PR ld/20030 * elf32-arm.c (is_thumb2_vldm): Account for T1 (DP) encoding. (stm32l4xx_need_create_replacing_stub): Rename ambiguous nb_regs to nb_words. (create_instruction_vldmia): Add is_dp to disambiguate SP/DP encoding. (create_instruction_vldmdb): Likewise. (stm32l4xx_create_replacing_stub_vldm): is_dp detects DP encoding, uses it to re-encode. ld/ PR ld/20030 * testsuite/ld-arm/arm-elf.exp: Run new stm32l4xx-fix-vldm-dp tests. Fix misnamed stm32l4xx-fix-all. * testsuite/ld-arm/stm32l4xx-fix-vldm-dp.s: New tests for multiple loads with DP registers. * testsuite/ld-arm/stm32l4xx-fix-vldm-dp.d: New reference file. * testsuite/ld-arm/stm32l4xx-fix-vldm.s: Add missing comment. * testsuite/ld-arm/stm32l4xx-fix-all.s: Add tests for multiple loads with DP registers. * testsuite/ld-arm/stm32l4xx-fix-all.d: Update reference.
