From 06e8d9861d16c5b7e6920ad0e89889ccf45c575a Mon Sep 17 00:00:00 2001 From: Claudiu Zissulescu Date: Mon, 25 Sep 2023 10:55:51 +0300 Subject: arc: Add new ARCv3 ISA to BFD. The new Synopsys's ARCv3 ISA is capable to run either 64-bit or 32-bit ISA. The new 32-bit ISA is not compatible with the old Synopsys ARCv1/ARCv2 ISA, however, it retains a lot of common concepts. Thus, this patch is reusing the old ARC BFD backend and adds the necessary bits for the new architecture in a similar way as it is done for RISCV backend. bfd/ xxxx-xx-xx Claudiu Zissulescu Cupertino Miranda * bfd/Makefile.am: Add ARC64 files. * bfd/Makefile.in: Regerate. * bfd/arc-got.h (TCB_SIZE): Depends on the target architecture.
