+
+ Platform.h is out of control Part 3: Move all ENABLE_* macros definitions in FeatureDefines.h
+ https://bugs.webkit.org/show_bug.cgi?id=206139
+
+ Reviewed by Anders Carlsson.
+
+ - Moves all remaining ENABLE_* defines out of Platform.h and into FeatureDefines.h
+ - Moves most, USE_UDIS86 and USE_ARM64_DISASSEMBLER are tangled up in the JIT definitions
+ still, HAVE_* and USE_* defines out of FeatureDefines.h and into Platform.h
+ - Where straigthforward, convert macro definitions into a canonical 3 line entry of the
+ form:
+
+ #if !defined(MACRO_NAME) && (<CONDITIONS HERE>)
+ #define MACRO_NAME 1
+ #endif
+
+ There is rarely (if ever) a resone to undefine or define one of these platform related
+ macros to 0 as the usage macros (e.g. HAVE(...), ENABLE(...), etc.) handle undefined as 0.
+ - Added a guard so that FeatureDefines.h can't be included directly, and must be included via
+ Platform.h. This is necessary as it depends heavily on macros defined in Platform.h
+ - Added numerous FIXMEs detailing follow up cleaning.
