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?
