Hello.
I have a question.
Can i replace the function "VirtualAlloc" to the function
"HeapAlloc"in the following code from v8?
If not, why?
void* OS::Allocate(const size_t requested,
size_t* allocated,
bool executable) {
// VirtualAlloc rounds allocated size to page size automatically.
size_t msize = RoundUp(requested, GetPageSize());
// Windows XP SP2 allows Data Excution Prevention (DEP).
int prot = executable ? PAGE_EXECUTE_READWRITE : PAGE_READWRITE;
LPVOID mbase = VirtualAlloc(NULL, msize, MEM_COMMIT | MEM_RESERVE,
prot);
if (mbase == NULL) {
LOG(StringEvent("OS::Allocate", "VirtualAlloc failed"));
return NULL;
}
ASSERT(IsAligned(reinterpret_cast<size_t>(mbase),
OS::AllocateAlignment()));
*allocated = msize;
UpdateAllocatedSpaceLimits(mbase, msize);
return mbase;
}
