error: unknown register name 'r0' in asm

[ksaker]

When try to compile, i have an error:

[arm64-v8a] Compile : base <= hook.c
~/adbi/instruments/base/jni/../hook.c:43:5: error: unknown register name 'r0' in asm
: "r0", "r1", "r7"

[Invincibl-e]

use the gcc compiler

I have the same problem, using gcc compiler alone, it gave me these errors

My solution is creating a Application.mk under the directory of jni:

APP_MODULES := base
APP_ABI := armeabi armeabi-v7a

ok. I found this project is not suitable for arm64, coz r0-r7 do not exist anymore, and x0-x7 instead.

And, if you wanna make this project work on arm64-v8a, some codes need to be edited, such as the inline assembly the compiler mentions, and codes about ELF32, the hook assembly codes, etc.
