Description

I get two complaints about unreachable code in sage/libs/pari/gen.pyx for toGEN (line 9197 after #12215) and _coerce_c_impl (line 9670 after #12215) and the compiler is correct if I read the code correctly. The edits causing this both are from the pre-trac ticket era (2007 and 2006 respectively)

Removed the code in question.

comment:2 Changed 9 years ago by cremona

The description mentions two blocks to be removed but the patch only removes one. Why?

comment:3 Changed 9 years ago by AlexGhitza

Ah, forgot to mention that the other block has already disappeared. You can see this by (a) looking at what happens when you apply the patch and rebuild sage--there are no other warnings about unreachable code; and/or (b) reading the very short function _coerce_c_impl and seeing that there are no issues.
