DexRun.c casts a float into an unsigned int #48

Open JamesNewton opened 5 years ago

DexRun.c casts a float into an unsigned int. This generates the warning: 

DexRun.c: In function 'SetParam':
DexRun.c:3868:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
  unsigned int *uia2 = *(unsigned int*)&fa2;
  ^
DexRun.c:3868:23: warning: initialization makes pointer from integer without a cast [-Wint-conversion]
  unsigned int *uia2 = *(unsigned int*)&fa2;
                       ^

To correct this, memcpy can be used:
