Optimizations to preprocessor's find_define().
- don't check for __FILE__ and __LINE__ until after we've checked our hash,
since this is the less likely case.
- Check against the hard-coded hash value of the strings "__FILE__" and
"__LINE__" to avoid unnecessary strcmp() calls.
This dropped the profile of this function from 20% of our total CPU time to
10%. Of that 10%, 70% is now the hashing function.
To use this in your project:
- Add mojoshader*.c and mojoshader*.h to your project.
- Compile mojoshader*.c
- If you don't have a C99-compliant compiler, like Microsoft Visual Studio,
you'll need to compile the .c files as C++ to get them to build.
- If you don't have cmake to generate mojoshader_version.h, you can either
add a blank file with that name, or add MOJOSHADER_NO_VERSION_INCLUDE to
your preprocessor definitions.
