Research direction
Reproduce the failure with the provided Docker command and autogen_bug.py example. Start at the assertion in /cinder/src/Jit/codegen/autogen.cpp:143 and trace the reported “No pattern found for opcode Fadd: Xxr” case, comparing behavior with and without @inline. Done means the inline version no longer aborts with this assertion.

Description
$ docker run -v $PWD:/vol -it --rm ghcr.io/facebookincubator/cinder-runtime:cinder-3.8 -X jit -m compiler --static vol/autogen_bug.py
JIT: /cinder/src/Jit/codegen/autogen.cpp:143 -- assertion failed: func != nullptr
No pattern found for opcode Fadd: Xxr
from __static__ import box, double, inline
@inline
def foo(a: double, b: double) -> double:
return b - a
def main():
c: double = 0.
for _ in range(10):
c += foo(.4, .97)
print('done', box(c))
if __name__ == '__main__':
main()
The problem goes away if @inline is removed.
