- Removed dead configuration in CMakeLists.txt.
- Used target_compile_options() instead of CMAKE_{C|CXX}_FLAGS.
- Turned on warnings on tests.
- Fixed various warnings for comparing signed with unsigned values.
- Removed dead code exposed by compiler warnings.
Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.
find . -name "*.h" -exec clang-format -i {} \;
find . -name "*.cpp" -exec clang-format -i {} \;
Use double quotes ("). They can be interspersed with
other whitespace characters, just like shell quoting.
A backslash (\) always escapes the next character.
The end of the stream always terminates the word.
Add AutoText struct to unit test utilities, to easily
make spv_text_t values and reference them as spv_text values.
