This directory is a Windows Hypervisor Platform projection of the `fasmg` core. It builds a normal command-line executable and a modern Win64 DLL that both run the same 32-bit assembler core inside a WHP partition.

Features [compressed] cacheable startup state which allows bypassing include files! (slower); support 4GB of memory for the fasmg core. DLL supports timeout, cancel and other options. (Different interface from standard DLL.)

The caching introduces an interesting use case: if you've engineered a product of various micro-controllers and written a DSL for fasmg to compile into code for your product. It's possible to distribute the cache for a special interface without distributing the include files! Be creative, you'll find other use-cases.

* Note: Uncompressing in fasmg/fasm2 directory is the intended structure.

The caching feature has been in the works for some time - many prior posts addressed concerns with fasmg/2 startup: cache compiler state in a meaningful way, FASM2 - Candidate to Benefit from Persistent Precompilation?, and I'm sure there are others.

It's possible to have a sufficiently complex source where cached startup would be faster, but presently that is not the case with any sources I'm aware of -- fasmg core is just too dense and algorithm efficient (and the host-side memory system is quite efficient).

This doesn't mean the caching couldn't be used for greater efficiency with fan-out of common source compiles. For example, a directory of small object file sources. They can all use the same memory mapped file, decompressed into the partition. One would need to engineer a WHvClonePartition, likely with a host-side copy-on-write semantic, and dozens of partitions could be spun up quite fast.

I'm not posting this to github -- it's just a feature for the board and those who chose to communicate here. Although the code is in the public domain, I hope you will respect this.
