Mmh, why do you have to add the support of LDR <Xt>, [<Xn|SP>, <R><m>]
while it's already supported?
ref_213 = ((((((((0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0)
Just means that you read the value 0 from your memory access [x2, x19]
.
I'm sorry for my ignorance and thank you for your patience. This is caused by my own lack of understanding.
Hello! I got symbolic expression
ref_213 = ((((((((0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) << 8 | 0x0) # LDR operation - LOAD access
When I try to symbolizeldr x19, [x2, x19]
which in this form:LDR <Xt>, [<Xn|SP>, <R><m>]
I tried to read the source code and found no handling of this type in
Triton\src\libtriton\arch\arm\aarch64\aarch64Semantics.cpp
. I read and try to understand the two provided:/* LDR <Xt>, [<Xn|SP>], #<simm> */
/* LDR <Xt>, [<Xn|SP>, #<simm>]! */
But adding support forLDR <Xt>, [<Xn|SP>, <R><m>]
is still difficult for me as a beginner.So for now, All I can do is feeding back the problem here and hope who can solve it. Thank you for your excellent framework.
