This is Python 2.7.2, compiled to .bc as follows:
Uncompress Python into two separate directories, one for native and one for JS.
In the JS one, do
emconfigure ./configure --without-threads --without-pymalloc --enable-shared
EDIT pyconfig.h, remove
HAVE_GCC_ASM_FOR_X87
HAVE_SIG* except SIGNAL_H
and *add*
#define PY_NO_SHORT_FLOAT_REPR
make
It will fail on lack of permissions to run Parser/pgen.
Go to the native one, do
./configure --without-threads --without-pymalloc
make
(Note: you don't need to let it complete, just enough for Parse/pgen is sufficient.)
cp Parser/pgen ../YOUR_JS_DIR/Parser/
Return to the JS one, do
chmod +x Parser/pgen
make
You will get an error on lack of permissions to run ./python. Ignore that, and do
llvm-link libpython2.7.so python -o python.bc
That's it!
Thanks to rasjidw for helping with this!
