Something is wrong with n-cell bignums, but let's make haste slowly.

Simon Brooke d9d789fdd0 Now creating the correct internal bignum representation 
add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.

Simon Brooke e5f40032e9 Now safely detecting (but not dealing with) integer overflow. 
Also printing and reading integers with comma separators.

Simon Brooke c21a762413 Much better GC, still a few things being missed. 2018-12-29 20:34:31 +00:00
Simon Brooke 2ec5d37305 Noticed that my notes files weren't being rendered by github 
Because .txt, not .md
 2018-12-29 16:39:20 +00:00
Simon Brooke 7b126ea979 Garbage collection now much better, not good 
There's clearly still a lot of things getting incremented but not decremented.
 2018-12-29 09:35:29 +00:00
Simon Brooke ad806de656 Freeing vector-space objects, apparently good. 
Not freeing enough cons-space objects, though!

Simon Brooke 6ee9f9b59a Begun work on bignums; changed integer size to 64 bits 
I'm fairly sure the size of a long int on my machines is 64 bit anyway, but for portability it needs to be explicit.

Simon Brooke 2c001a5f98 Sorting out what looked like a premature freeing bug. 
It wasn't, but in investigating I tightened up allocation and deallocation in frames.
