The jitdump header contains a "magic" field that is defined to hold the value 0x4A695444 as u32 in native endianness. (This allows consumers of the file to detect the endianness of the platform where the file was written, and apply it when reading other fields.) However, current code always writes 0x4A695444 in little-endian byte order, even on big-endian system. This makes consumers fail when attempting to read files written on big-endian platforms. Fixed by always writing the magic in native endianness.
This is the wasmtime-profiling crate, which contains runtime performance
profiling support for Wasmtime.
