From 493ffac5aad8c39215702435c2506fd4d3077191 Mon Sep 17 00:00:00 2001 From: Dimitar Dimitrov Date: Wed, 9 May 2018 11:39:32 +0100 Subject: [PATCH] Fix binary compatibility between GCC and the TI compiler for the PRU target. My original implementation for LDI32 pseudo does not conform to the TI ABI. I wrongly documented my TI PRU ELF object files inspection, which got propagated into my binutils implementation. Issue was exposed when running the GCC ABI testsuite against TI toolchain. According to TI ABI, LDI32 must use first LDI instruction to load the MSB 16bits, and second LDI instruction for the LSB 16bits. This patch will break binary compatibility with previously released binutils versions for PRU. Still, I think it is better to fix binutils to conform to the chip vendor ABI. bfd * elf32-pru.c (pru_elf32_do_ldi32_relocate): Make LDI32 relocation conformant to TI ABI.
