[pypy-dev] Unknown Operation Re: What Causes An Ambiguous low-level helper specialization Error?

[Andrew Francis]

Hello Amaury:

Yes you are right! I commented out the print statement. I'll fix that later (it is there to check if the code is emitting the correct answers. I can change that a bunch of asserts). 


Out of curiosity, I thought there was some sort of rpython lint utility out there? Perhaps I can use that to help me catch those sort of errors (I wrote a version of the code in Python to catch mistakes). 


However now I am getting:

[rtyper] -=- specialized 2 more blocks -=-
[canraise:WARNING] Unknown operation: stm_transaction_boundary
[canraise:WARNING] Unknown operation: stm_transaction_boundary
[canraise:WARNING] Unknown operation: stm_transaction_boundary

Again, the command I am using to compile the code is:
python ../../goal/translate.py --stm --gc=none bank.py

I have bank.py in the same directory as targetdemo.py and I use the same command.

I can't wait to see this code compile! Bank accounts are the "hello world" of transactional programming!

Cheers,
Andrew

Hi,

This one is easy: you are formatting a float with %d,
which is not supported by RPython.
For your debug output, use %s instead.
