Cleanup: Make C++ constant style consistent and remove CONSTEXPR define
We have two cleanup issues related to C++ constants:
- Now that do not support VS2013 and have C++11 everywhere we can remove this in clients/drcachesim/common/utils.h:
/* TODO(i#2924): Remove this and others like it once we stop supporting VS2013. */
#if defined(WINDOWS) && _MSC_VER < 1900
# define CONSTEXPR const /* 'constexpr' not supported */
#else
# define CONSTEXPR constexpr
#endif
- We should make the constant variable names consistent in drcachesim. The official style from https://dynamorio.org/page_code_style.html#autotoc_md122 is to use all caps, yet a number of files are using kCamelCase.
