// This header defines types of ELF "notes" that are embedded sections. These
// can be read by ElfImageReader in the snapshot library, and are created in
// client modules. All notes used by Crashpad use the name "Crashpad" and one of
// the types defined here. Note that this file is #included into .S files, so
// must be relatively plain (no C++ features).

#define CRASHPAD_ELF_NOTE_NAME "Crashpad"

// Used by ElfImageReader for testing purposes.
#define CRASHPAD_ELF_NOTE_TYPE_SNAPSHOT_TEST 1

// Used by the client library to stash a pointer to the CrashpadInfo structure
// for retrieval by the module snapshot. 'OFNI' == 0x4f464e49 which appears as
// "INFO" in readelf -x.
