-Extra SIGTRAP when breakpoint + watchpoint occur on same instruction
-Description of problem:
-If a breakpoint and watchpoint occur on the same instruction in TCG, gdb receives a breakpoint notification, a watchpoint notification, and then a SIGTRAP not corresponding to any set breakpoint/watchpoint.
-Steps to reproduce:
-Start QEMU via:
-
-```
-./qemu-system-i386 -display none -accel tcg -kernel kernel.elf -s -S
-```
-
-Here's the gdb session:
-
-```
-(gdb) file kernel.elf
-Reading symbols from kernel.elf...done.
-(gdb) tar rem :1234
-Remote debugging using :1234
-0x0000fff0 in ?? ()
-(gdb) b _start
-Breakpoint 1 at 0x10000c: file kernel.s, line 17.
-(gdb) c
-Continuing.
-
-Breakpoint 1, _start () at kernel.s:17
-17 mov eax, 3
-(gdb) b bp
-Breakpoint 2 at 0x100011: file kernel.s, line 20.
-(gdb) watch *(int*)&value
-Hardware watchpoint 3: *(int*)&value
-(gdb) c
-Continuing.
-
-Breakpoint 2, bp () at kernel.s:20
-20 mov dword ptr value, eax
-(gdb) c
-Continuing.
-
-Hardware watchpoint 3: *(int*)&value
-
-Old value = 0
-New value = 3
-done () at kernel.s:23
-23 jmp done
-(gdb) c
-Continuing.
-
-Program received signal SIGTRAP, Trace/breakpoint trap.
-done () at kernel.s:23
-23 jmp done
-```
-Additional information:
-This patch fixes it by disabling the extra debug interrupt if the CPU is already singlestepping, but I'm not certain it's the 'correct' fix?
