From f5ada87cec82616c122a43ff750eb617457f3b0f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20Chigot?= Date: Tue, 16 Feb 2021 10:41:57 +0100 Subject: [PATCH 5/6] aix: implement R_TOCU and R_TOCL relocations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement support for largetoc on XCOFF. R_TOCU and R_TOCL are referenced by the new BFD defines: BFD_RELOC_PPC_TOC16_HI and BFD_RELOC_PPC_TOC16_LO. A new toc storage class is added XMC_TE. In gas, add a function to transform addis format used by AIX "addis RT, D(RA)" into the ELF format "addis RT, RA, SI". bfd/ChangeLog: 2020-11-20 Clément Chigot * bfd-in2.h (BFD_RELOC_PPC_TOC16_HI, BFD_RELOC_PPC_TOC16_LO): New defines * coff-rs6000.c (xcoff_calculate_relocation): Call xcoff_reloc_type_¨toc for R_TOCU and R_TOCL.
