| michael@0 | 24 | /* |
| michael@0 | 25 | * Default implementation of UMemory::new/delete |
| michael@0 | 26 | * using uprv_malloc() and uprv_free(). |
| michael@0 | 27 | * |
| michael@0 | 28 | * For testing, this is used together with a list of imported symbols to verify |
| michael@0 | 29 | * that ICU is not using the global ::new and ::delete operators. |
| michael@0 | 30 | * |
| michael@0 | 31 | * These operators can be implemented like this or any other appropriate way |
| michael@0 | 32 | * when customizing ICU for certain environments. |
| michael@0 | 33 | * Whenever ICU is customized in binary incompatible ways please be sure |
| michael@0 | 34 | * to use library name suffixes to distinguish such libraries from |
| michael@0 | 35 | * the standard build. |
| michael@0 | 36 | * |
| michael@0 | 37 | * Instead of just modifying these C++ new/delete operators, it is usually best |
| michael@0 | 38 | * to modify the uprv_malloc()/uprv_free()/uprv_realloc() functions in cmemory.c. |
| michael@0 | 39 | * |
| michael@0 | 40 | * Memory test on Windows/MSVC 6: |
| michael@0 | 41 | * The global operators new and delete look as follows: |
| michael@0 | 42 | * 04F 00000000 UNDEF notype () External | ??2@YAPAXI@Z (void * __cdecl operator new(unsigned int)) |
| michael@0 | 43 | * 03F 00000000 UNDEF notype () External | ??3@YAXPAX@Z (void __cdecl operator delete(void *)) |
| michael@0 | 44 | * |
| michael@0 | 45 | * These lines are from output generated by the MSVC 6 tool dumpbin with |
| michael@0 | 46 | * dumpbin /symbols *.obj |
| michael@0 | 47 | * |
| michael@0 | 48 | * ??2@YAPAXI@Z and ??3@YAXPAX@Z are the linker symbols in the .obj |
| michael@0 | 49 | * files and are imported from msvcrtd.dll (in a debug build). |
| michael@0 | 50 | * |
| michael@0 | 51 | * Make sure that with the UMemory operators new and delete defined these two symbols |
| michael@0 | 52 | * do not appear in the dumpbin /symbols output for the ICU libraries! |
| michael@0 | 53 | * |
| michael@0 | 54 | * If such a symbol appears in the output then look in the preceding lines in the output |
| michael@0 | 55 | * for which file and function calls the global new or delete operator, |
| michael@0 | 56 | * and replace with uprv_malloc/uprv_free. |
