For a while I have been cleaning up warnings when building with clang.
There are currently only two sources of warnings left: Wcast-align and Wgnu.
I am not convinced that fixing up those up is feasible so I run with them
disabled to spot regressions. E.g. clang is a bit more strict wrt to unused
variables with the cleanup attribute and I have fixed a number of those since.
Like the other options in autogen.sh I have a shortcut for clang as well. I use
'l' for llvm.
elif [ "x$1" = "xa" ]; then
./configure CFLAGS='-g -O0 -Wsuggest-attribute=pure -Wsuggest-attribute=const -ftrapv' --enable-kdbus $args
make clean
+elif [ "x$1" = "xl" ]; then
+ ./configure CC=clang CFLAGS='-g -O0 -ftrapv -Wno-cast-align -Wno-gnu' --enable-kdbus $args
+ make clean
else
