Take a local look at the source code in this folder:
https://github.com/bitcoin/bitcoin/tree/master/src/secp256k1/src
Notice the 1 and 2 megabyte source files.
This leads to analysis problems. Long wait times.
My suggestion/request is that this source code is changed such that these big look-up tables are read from disk instead of dumped into c and h files.
This would reduce the source files considerably and would solve analysis problems. Right now only way to solve analysis problems is to delete this particular folder.
