asm("int3"); /*trap*/ query

Wkerry:
In the code there are a few of the following calls:
asm("int3"); /*trap*/

This works for x86 based CPU's, but when I use google to check what the arm equivalent it is not the same.

I have seen some historical posts of people building C::B on a RPi. As such it may be an idea to add protection around the asm("int3"); for x86 CPU's only and add support for ARM so that in the future when/if C::B does officially support running on RPi or other ARM SBC's/PC's then the code should hopefully then require less changes.

Which code do you see the int3's in that are unprotected?

ollydbg:
Hi, Pecan, my guess is that your recent to commits have some code change related to the "int3" instruction.

Maybe, we can find a way for both X86 based CPU and ARM based CPU.

Wkerry:
It was in the latest SVN change, but I am 1000% confident the same int 3 is in other places as I have included it in apps I have done where I enable it in a debug build.

This is some thing to thin about when you see an "int 3".

All use of "int3" has been commented out. SVN revision 13608
