Crashpad doesn’t use AVX-512, but when receiving replies to exceptions forwarded to ReportCrash, may see buffers large enough to contain AVX-512 thread state. This can result in messages like “UniversalExceptionRaise: (ipc/rcv) msg too large (0x10004004)”. I386_THREAD_STATE_MAX has increased from 224 to 614 in the 10.13 SDK, meaning that the maximum supported size for old_state and new_state in [mach_]exception_raise_state[_identity]() has increased from 896 to 2,456 bytes. This constant defines the size of the buffer that these MIG-generated routines will work with. By providing this definition in compat, the buffer size is increased when building with older SDKs. Note that on the “send” side, the size of the message given to mach_msg() will be trimmed to include only the valid part of the state area based on the stateCnt field, so increasing the value to 614 here won’t result Crashpad sending messages this large. That would be a potential interoperability concern with older OS versions.
