[Qemu-devel] arm vfp support in gdbstub

[Vladimir Vukicevic]

Howdy,

gdb doesn't seem to know what to do with vfp registers on arm, and  
qemu wasn't sending them anyway.  The attached patch and gdb tdesc  
files let you examine fp state via the debugger.  What's the right way  
to do this?  Ideally it would be selectable at runtime in some way,  
and gdb should be told what the processor desc is without having to  
manually do it.  Note that I left the FPA hole because  
org.gnu.gdb.arm.core puts cpsr at regnum 25, so there would end up  
being a hole there anyway.

To use, load the tdesc in gdb via 'set tdesc filename arm-with- 
vfp.xml', then target remote qemuhost:port as normal with a qemu built  
with the attached patch.
