[LLVMdev] load bytecode from string for jiting problem
I mad the change, and still have the problem.
I investigate more the source code of llvm.
First, I change isRawBitcode function to print the content of the
parameter like this:
original:
http://llvm.org/docs/doxygen/html/ReaderWriter_8h_source.html#l00081
inline bool isRawBitcode(const unsigned char *BufPtr,
const unsigned char *BufEnd) {
// These bytes sort of have a hidden me...

[LLVMdev] load bytecode from string for jiting problem
...odule with
parseBitcodeFile.
This two step works.
After, while the compiled program is running, I try to read and parse
this global variable for jiting the function.
1) I read the global variable with
StringRef sr (gv, gv_length);
2) I manually test this bytecode by
(inspired by inline bool isRawBitcode(const unsigned char *BufPtr,
const unsigned char *BufEnd) at
http://llvm.org/docs/doxygen/html/ReaderWriter_8h_source.html#l00067)
if (sr.str()[0] == 'B')
std::cout << "B ok\n";
if (sr.str()[1] == 'C')
std::cout << "C ok\n";
if (sr.str()...
