Hi, this PR adds support for 64-bit memories, by adjusting the APIs to match the C API introduced with bytecodealliance/wasmtime#3153 and bytecodealliance/wasmtime#3182.
It contains the following changes:
Config.WithMemory64()for enabling the Memory64 proposal.Memory,MemoryExportandMemoryImportthat work with pages (likeMinimum,Maximum,Grow()) to use alonginstead ofuint. (I choselonginstead ofulongbecause memory pages cannot exceed2**48, and becauseulongisn't CLS-compliant.)(This will be a breaking change.)
Is64Bitproperty that specifies whether the memory is a 64-bit memory.Memorywith more than 32767 pages #166 are able to access a memory beyond the 4 GiB area, and that the new APIs correctly retrieve the memory type definitions.Additionally, this fixes previously incorrect definitions of native functions
wasmtime_memory_sizeandwasmtime_memory_grow, where the parameter incorrectly useduintinstead ofulongafter the changes introduced in the Wasmtime C API.Also, I noticed that for native Config functions taking a C
boolparameter, the[MarshalAs]attribute was missing, which meant these parameter were marshaled by .NET as 4-byteBOOLinstead of an 1-byte value.What do you think?
Thanks!
