Expand description

A trap code describing the reason for a trap.

All trap instructions have an explicit trap code.

Variants§

§

StackOverflow = 0

The current stack space was exhausted.

On some platforms, a stack overflow may also be indicated by a segmentation fault from the stack guard page.

§

HeapAccessOutOfBounds = 1

A heap_addr instruction detected an out-of-bounds error.

Note that not all out-of-bounds heap accesses are reported this way; some are detected by a segmentation fault on the heap unmapped or offset-guard pages.

§

HeapMisaligned = 2

A heap_addr instruction was misaligned.

§

TableAccessOutOfBounds = 3

A table_addr instruction detected an out-of-bounds error.

§

IndirectCallToNull = 4

Indirect call to a null table entry.

§

BadSignature = 5

Signature mismatch on indirect call.

§

IntegerOverflow = 6

An integer arithmetic operation caused an overflow.

§

IntegerDivisionByZero = 7

An integer division by zero.

§

BadConversionToInteger = 8

Failed float-to-int conversion.

§

UnreachableCodeReached = 9

Code that was supposed to have been unreachable was reached.

§

UnalignedAtomic = 10

An atomic memory access was attempted with an unaligned pointer.
