示例1: setFileStream
void MetaProcessor::setFileStream(llvm::StringRef file, bool append, int fd,
llvm::SmallVector<llvm::SmallString<128>, 2>& prevFileStack) {
// If we have a fileName to redirect to store it.
if (!file.empty()) {
prevFileStack.push_back(file);
// pop and push a null terminating 0.
// SmallVectorImpl<T> does not have a c_str(), thus instead of casting to
// a SmallString<T> we null terminate the data that we have and pop the
// 0 char back.
prevFileStack.back().push_back(0);
prevFileStack.back().pop_back();
if (!append) {
FILE * f;
if (!(f = fopen(file.data(), "w"))) {
llvm::errs() << "cling::MetaProcessor::setFileStream:"
" The file path " << file.data() << "is not valid.";
} else {
fclose(f);
}
}
// Else unredirection, so switch to the previous file.
} else {
// If there is no previous file on the stack we pop the file
if (!prevFileStack.empty()) {
prevFileStack.pop_back();
}
}
}示例2: alloc
void* alloc() {
if (free_chunks.empty()) {
int protection = PROT_READ | PROT_WRITE | PROT_EXEC;
int flags = MAP_PRIVATE | MAP_ANONYMOUS | MAP_32BIT;
char* addr = (char*)mmap(NULL, region_size, protection, flags, -1, 0);
for (int i = 0; i < region_size / chunk_size; ++i) {
free_chunks.push_back(&addr[i * chunk_size]);
}
}
return free_chunks.pop_back_val();
}示例3: empty
bool empty() const { return ToHandle.empty(); }
