--- Comment #54 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
Hmm, I see. What I am trying to accomplish is, put the target
attribute on every function that calls directly or in-directly
to CONTINUE_UNWINDING. And do that only for ARM.
For gdc_personality it is straight forward to do, as you pointed out.
But for __gdc_personality and scanLSDA what I would like to do is
static if (GNU_ARM_EABI_Unwinder)
{
@attribute("target", ("general-regs-only"))
}
private _Unwind_Reason_Code __gdc_personality(_Unwind_Action actions,
_Unwind_Exception_Class
exceptionClass,
_Unwind_Exception* unwindHeader,
_Unwind_Context* context)
{
...
but that does not work, what would work is
static if (GNU_ARM_EABI_Unwinder)
{
@attribute("target", ("general-regs-only"))
private _Unwind_Reason_Code __gdc_personality(_Unwind_Action actions,
_Unwind_Exception_Class
exceptionClass,
_Unwind_Exception* unwindHeader,
_Unwind_Context* context)
{
...
}
}
else
{
private _Unwind_Reason_Code __gdc_personality(_Unwind_Action actions,
_Unwind_Exception_Class
exceptionClass,
_Unwind_Exception* unwindHeader,
_Unwind_Context* context)
{
...
}
}
duplicating all that code is of course not an option.
