-dump-repro-on-failure option (#1095)
* Small typo fix
|
|
* OffsetContainer with unit tests.
* State serialization working with OffsetContainer.
* Fixes to make work with OffsetContainer.
* Added OffsetContainer documentation.
* Remove RelativeContainer.
* Fix problem with + on Offset32Ptr on windows x86 target.
* * Made OffsetBase a base class of OffsetContainer.
* Added MemoryOffsetBase to just handle being a chunk of memory.
* * Use operator[] to access contents of OffsetContainer
* Fix the type hash to work across different size_t sizes.
* Fixed some Offset type related comments.
* Fix bug around using asBase, because it returns a reference just using 'auto' will means it becomes a value type.
Remove assignment and copy ctor from OffsetBase.
* Evaluation order of assignment can lead to wrong behavior with Offset32Ptr/raw pointers. Document the fact, and fix in StateSerializeUtil.

* Strip IR after front-end steps are done
The main feature of this change is to unconditonally strip out the `IRHighLevelDeclDecoration`s in an IR module once the "mandatory" IR passes in the front end have run. This ensures that later IR passes (e.g., code emission) *cannot* rely on AST-level information to get their job done.
Since I was already writing a pass to remove some instructions at the end of the front-end passes, I went ahead and also made the `-obfuscate` flag apply to the front-end IR generation by causing it to strip `IRNameHintDecoration`s while it is doing the other stripping. With this, the main identifying information left in IR modules (other than semantics and entry-point names) is mangled name strings for imported/exported symbols.
A few other things got changes along the way:
* Removed the `.expected` file for one of the tests, where that file seemingly shouldn't have been checked in at all.
* Updated the signature of the DCE pass both so that it doesn't require a back-end compile request (it wasn't using it anyway), and so that it takes some options to decide whether to keep symbols marked `[export(...)]` alive (the front-end wants to keep these, while back-end passes currently need to be able to eliminate them).
* Moved the `obfuscateCode` flag from the back-end compile request to the base class shared between front- and back-end requests, and updated the options and repro logic to set both as needed. An obvious improvement in the future would be to have the front- and back-end requests share these settings by referencing a single common object in the end-to-end case, rather than each having their own copy.
* Removed logic that was keeping layout instructions alive in DCE, even if they weren't used. This seems to have been a vestige of an intermediate step between AST and IR layout.
* fixup: add the new files

Use slang.h for main header.
slang-cpp-prelude.h can now just include what it needs (relative to prelude directory) and define the few remaining things/work arounds.
* Fix typo.
