<br class="">
When I used llvm-objdump to disassemble an ELF armv7 or thumb I have this error message:<br class="">
<br class="">
llvm-objdump: warning: invalid instruction encoding<br class="">
<br class="">
This message appears directly into the output and the output is mostly wrong (the invalid instruction create a shift in the addresses) :<br class="">

The binaries I try to read are c++ dynamic libraries for Android.<br class="">
<br class="">
I have used the following parameters:<br class="">
<br class="">
-llvm-objcdump mylib.so -d -arch=arm<br class="">
-llvm-objcdump mylib.so -d -arch=armv7<br class="">
-llvm-objcdump mylib.so -d -arch=thumb<br class="">
<br class="">
or with the following triples:<br class="">
<br class="">
armv7-none-linux-android<br class="">
thumbv7-none-linux-android<br class="">
<br class="">
Does anyone know why I have this error? Am I missing some input parameters?<br class="">
<br class="">
This is strange because it works great on iOS binaries (both thumb or arm).<br class="">
<br class="">
Greetings,<br class="">
<br class="">
Johan<br class="">
