* remove disabled (and obsolete) ttypetraits; rename ttypetraits2 => ttypetraits
* D20200105T085828 fix super strange bug that causes CI to fail: builds.sr.ht with: `Error: Settle timed out after 120 attempts`
* [FEATURE] rst parser respect :start-after: in include
Rst parser now respects `:start-after:` and `:end-before:` attributes
for `include` directive.
* [DOC] include directive parsing proc update
* [TEST] Added unit tests for include rst directive in `rst` module
* VM: allow certain hardcoded special var variables at CT
* VM: allow all importc var, cast[int](ptr)
* fix tests tests/vm/tstaticprintseq.nim, tests/cpp/t8241.nim
* VM: == works for ptr/pointer nodes
* bugfix: ==, cast now also works for pointer, not just ptr
* VM supports cast PtrLikeKinds <=> PtrLikeKinds / int
* improve cname handling
* fixup + bug fix
* VM: support cast from ref to int
* address comment: opcLdGlobalDeref => opcLdGlobalDerefFFI
* defensive check against typ == nil
This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior.
Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.
Stack traces on an unbuffered stderr get out of sync with line-buffered
stdout - usually on Windows terminals or CI logs. This fixes it by
calling C's fflush() on the output buffer in the procedure used for
printing stack traces.
* libbacktrace support
* switch to a generic stack trace overriding mechanism
When "nimStackTraceOverride" is defined, once of the imported modules
can register its own procedure to replace the default stack trace
generation by calling `registerStackTraceOverride(myOwnProc)`.
Tested with `./koch boot -d:release --debugger:native -d:nimStackTraceOverride --import:libbacktrace`
for the compiler itself and `./bin/nim c -r -f --stacktrace:off --debugger:native -d:nimStackTraceOverride --import:libbacktrace foo.nim`
for an external program.
* make the StackTraceOverrideProc {.noinline.}
