Function Documentation

threadContextIsAArch64()

static bool threadContextIsAArch64 ( const ThreadContext *  ctx )

inlinestatic

Determines whether a thread context belong to an AArch64 process based on the PSR.

Parameters

[in]

ctx

Thread context to which PSTATE/cspr has been dumped to.

Returns

true if and only if the thread context belongs to an AArch64 process.

threadExceptionIsAArch64()

static bool threadExceptionIsAArch64 ( const ThreadExceptionDump *  ctx )

inlinestatic

Determines whether a ThreadExceptionDump belongs to an AArch64 process based on the PSTATE.

Parameters

[in]

ctx

ThreadExceptionDump.

Returns

true if and only if the ThreadExceptionDump belongs to an AArch64 process.
