<pre>LLDB fails to build against Python 2.X, I get the following error message:
/path/to/llvm-build/src/lldb/source/Plugins/ScriptInterpreter/Python/PythonReadline.cpp:52:25:
error: use of undeclared identifier 'PyMem_RawMalloc'; did you mean
'PyMem_Malloc'?
char *ret = (char *)PyMem_RawMalloc(1);
^~~~~~~~~~~~~~~
PyMem_Malloc
/path/to/llvm-build/workstation-sysroot/usr/include/python2.7/pymem.h:52:20:
note: 'PyMem_Malloc' declared here
PyAPI_FUNC(void *) PyMem_Malloc(size_t);
^
/path/to/llvm-build/src/lldb/source/Plugins/ScriptInterpreter/Python/PythonReadline.cpp:60:23:

char *ret = (char *)PyMem_RawMalloc(n + 2);

1 warning and 2 errors generated.
According to the Python documentation, PyMem_RawMalloc() was only introduced in
3.4: <a href="https://docs.python.org/3/c-api/memory.html">https://docs.python.org/3/c-api/memory.html</a>
Looking at the cherry-picks between llvmorg-9.0.0-rc5 and llvmorg-9.0.1-rc1, I
suspect that this is caused by <a href="https://reviews.llvm.org/D69793">https://reviews.llvm.org/D69793</a>.</pre>
