Jon Ross-Perkins b828093c87 Start checking for a few possible resource exhaustion scenarios for explorer (#2793) 
I couldn't figure out a way to actually hit a reasonable out-of-memory case once I add the maximum interpreter step count. However, the step count limit seems more important.

I've moved the todo stack limit out of function calls because there are plenty of ways to build up the todo stack without any function calls.

Fixes #2791

Richard Smith 782bd87316 AST cloning mechanism (#2699) 
This is intended to be used for template instantiation, but for now takes no stance as to what it's cloning.

This is tested by parsing and cloning all of our test files, and checking that the result of converting each AST to proto is the same as the result of cloning and then converting each AST to proto.

Richard Smith 9fcbad8a42 Add factory function for empty source location. (#2328) 
This is intended to be used only when creating source locations that are known to be ignored because they are fed into operations whose diagnostics are discarded and that do not store the location in any created object.

As requested in review of #2321.

Geoff Romer be961dca3a Update and clarify error documentation (#2262) 2022-10-05 13:23:39 -07:00
Richard Smith 8f0f69b65f Remove RuntimeError / CompilationError. (#2258) 
Instead, work out the prefix for an error based on whether it was produced during parsing, semantic analysis, or when running the program.

Richard Smith 7a67715ac5 Error: track message and prefix/location separately. (#1529) 
This allows us to combine multiple Errors together without repeating the prefix
information. Also fixes several cases where two "COMPILATION ERROR" prefixes
would be prepended to the same message when errors with prefixes and locations
were produced by the lexer and parser.
