| 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. |
