FPEmulator_ExceptionDump

(SWI &40486)

Use

The purpose of this call is to return a pointer to the register exception dump.

Notes

When a floating point exception trap is generated, the floating point system stores the current FP registers in an internal exception dump using FPEmulator_SaveContext. This call returns a pointer to that register dump.
The Debugger module provides a ShowFPRegs command to view the dump contents.

On a floating point trap, the integer registers are also stored in the current exception register dump (OS_ChangeEnvironment 13?OS_ChangeEnvironment 13) so they can be viewed using ShowRegs. Note that floating point registers are not stored on other exceptions, such as data aborts.

Contexts are only available from FPEmulator 4.12 and later.
