From da8a9d695b3c4b9397b5d9a27660bfa48af8d707 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. --- libgcc/config.host | 4 ++-- libgcc/config/or1k/t-crtstuff | 2 ++ 2 files changed, 4 insertions(+), 2 deletions(-) create mode 100644 libgcc/config/or1k/t-crtstuff diff --git a/libgcc/config.host b/libgcc/config.host index 50f0006..8ca7a00 100644 --- a/libgcc/config.host +++ b/libgcc/config.host @@ -1119,12 +1119,12 @@ nios2-*-*) extra_parts="$extra_parts crti.o crtn.o" ;; or1k-*-linux*) - tmake_file="$tmake_file or1k/t-or1k" + tmake_file="$tmake_file or1k/t-or1k or1k/t-crtstuff" tmake_file="$tmake_file t-softfp-sfdf t-softfp" md_unwind_header=or1k/linux-unwind.h ;; or1k-*-*) - tmake_file="$tmake_file or1k/t-or1k" + tmake_file="$tmake_file or1k/t-or1k or1k/t-crtstuff" tmake_file="$tmake_file t-softfp-sfdf t-softfp" ;; pdp11-*-*) diff --git a/libgcc/config/or1k/t-crtstuff b/libgcc/config/or1k/t-crtstuff new file mode 100644 index 0000000..dcae7f3 --- /dev/null +++ b/libgcc/config/or1k/t-crtstuff @@ -0,0 +1,2 @@ +# Compile crtbeginS.o and crtendS.o with -mcmodel=large +CRTSTUFF_T_CFLAGS_S += -mcmodel=large -- 2.7.4
