i am analysing a crash, the crash occurs in a function that its always on use, if set a break point in this function always stop the program.
When the crash occurs, overwrite mm3 register, i want when overwrite mm3 with my values use the breakpoint.
the original estate of mm3 register its 0:0:e3cb:f144, when crash its aaaa:aa00:0:0.
when try this :
bp abpatch ".if @mm3 = aaaa:aa00:0:0 {} .else {gc}"
error, i cant use ":" on bp
if try this:
bp abpatch ".if @mm3 = aaaaaa000:0 {} .else {gc}"
or
bp abpatch ".if (@mm3 & 0x0`ffffffff) = 0x0`aaaaaa0000 {} .else {gc}"
Program crash and dont stop.
commonly i analyse the crash with -4 at the address that function crash, but now this function is always running on the program.
I put aaaa for easy location.
I think too need stop just before mm3 have got this values, but i don't know :(
How I can put a break point on a mm3 register?? any other solution for this ??
Any help or suggestion? . Thank you in advanced.
