- 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.
