From c544a63928406b706b8493fd9b8ca2136b433cf0 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Wed, 21 Apr 2021 05:33:15 +0900 Subject: [PATCH] or1k: Use cmodel=large when building crtstuff When linking gcc runtime objects into large binaries the link may fail with the below errors. This will happen even if we are building with -mcmodel=large. /home/shorne/work/openrisc/output/host/lib/gcc/or1k-buildroot-linux-uclibc/10.3.0/crtbeginS.o: in function `deregister_tm_clones': crtstuff.c:(.text+0x3c): relocation truncated to fit: R_OR1K_GOT16 against undefined symbol `_ITM_deregisterTMCloneTable' /home/shorne/work/openrisc/output/host/lib/gcc/or1k-buildroot-linux-uclibc/10.3.0/crtbeginS.o: in function `register_tm_clones': crtstuff.c:(.text+0xc0): relocation truncated to fit: R_OR1K_GOT16 against undefined symbol `_ITM_registerTMCloneTable' This patch builds the gcc crtstuff binaries always with the -mcmodel=large option to ensure they can be linked into large binaries. libgcc/ChangeLog: PR target/99783 * config.host (or1k-*, tmake_file): Add or1k/t-crtstuff. * config/or1k/t-crtstuff: New file.
