I can offer another bit of information for this software development discussion. The following build settings were active in my “Makefile” for this Linux test case. … HOSTCFLAGS = -Wall -Wmissing-prototypes -Wstrict-prototypes -O0 -fomit-frame-pointer -std=gnu89 … The affected source file can be compiled for the processor architecture “x86_64” by a tool like “GCC 6.4.1+r251631-1.3” from the software distribution “openSUSE Tumbleweed” with the following command example. my_cc=/usr/bin/gcc-6 \ && my_module=drivers/infiniband/hw/mlx4/main.o \ && git checkout next-20171009 \ && make -j4 CC="${my_cc}" HOSTCC="${my_cc}" allmodconfig "${my_module}" \ && size "${my_module}" \ && git checkout next_fine-tuning_in_mlx4_1 \ && make -j4 CC="${my_cc}" HOSTCC="${my_cc}" allmodconfig "${my_module}" \ && size "${my_module}" Do you find the following details useful for further clarification? text: -32 data: 0 bss: 0 Regards, Markus -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
