* koch boot --gc:arc now passes the nim stage
... but generates invalid C code
* Move it closer to where its used
* Try something else
* Poor mans var
* Use UncheckedArray instead
* Fix typeSym.getImpl for ref types
* Fix a codegen issue affecting the test suite of nim-beacon-chain
* Fix tests/stdlib/tjsonmacro
To understand the fix better it may help to take a look
at the history of the replaced code.
The nil check that is removed in this commit was introduced
in another fix that failed to identify the root cause of the
issue - namely that we allow an object type to exist for which
no ast is present:
https://github.com/nim-lang/Nim/pull/9601/files
The original intention of the code is more obvious here:
https://github.com/nim-lang/Nim/pull/9538/files
* new syntax for lvalue references: `var b {.byaddr.} = expr`
* on type mismatch, `???(0, 0)` not shown anymore
* * compiler now lowers `var a: {.foo.}: MyType = expr` to foo(a, MyType, expr)
* new pragmas.byaddr defined in pure library code exploiting this lowering
* skip `template foo() {.pragma.}`
* fix#13538 sigmatch now sorted and has reliable order
* re-enable tests that were disabled because of that bug
* fix remaining tests and un-disable 2 other tests that were affected by this bug
* config update
* disable a questionable test
* remove c++ exception handling IDs, new impl doesn't require it anymore
* C++ based exceptions finally work
* fixes bootstrapping problem in C++ mode
* teach GCC it's 2020 now
* more bugfixes for C++ based exception handling
* apply cooldome's patch
* another attempt to enable C++11
* bug fix
