Pull request overview
Updates the WASM/CoreCLR corerun host to allow growth up to a 4GB WebAssembly linear memory limit, and re-enables a previously skipped JIT regression test that exercises very large array allocations.
Changes:
- Increase
corerun’s Emscripten-sMAXIMUM_MEMORYfrom 2GB to 4GB for browser/wasm builds. - Remove the WASM-targeted
ActiveIssueAttributeskip fromjit64/regress/vsw/373472to re-enable the test on WASM.

src/coreclr/hosts/corerun/CMakeLists.txt |
Raises Emscripten maximum memory setting to 4GB so large allocations required by runtime tests can succeed. |
