ARM64e未适配

[sthyuhao]

我这打静态库的时候出现编译失败的问题

[sthyuhao]

------------命令(xcodebuild build -workspace gen/App.xcworkspace -scheme XXX -configuration 'Debug' -sdk iphoneos -arch 'arm64e' SYMROOT='../../BuildTemp')执行错误------------

/*

• By default, the pointer fields in the arm_thread_state64_t structure are
• opaque on the arm64e architecture and require the use of accessor macros.
• This mode can also be enabled on the arm64 architecture by building with
• -D__DARWIN_OPAQUE_ARM_THREAD_STATE64=1.

  #if defined(arm64) && defined(LP64)

#if __has_feature(ptrauth_calls)
#define __DARWIN_OPAQUE_ARM_THREAD_STATE64 1
#define __DARWIN_PTRAUTH_ARM_THREAD_STATE64 1
#endif /* __has_feature(ptrauth_calls) */

#ifndef __DARWIN_OPAQUE_ARM_THREAD_STATE64
#define __DARWIN_OPAQUE_ARM_THREAD_STATE64 0
#endif

#else /* defined(arm64) && defined(LP64) */

#undef __DARWIN_OPAQUE_ARM_THREAD_STATE64
#define __DARWIN_OPAQUE_ARM_THREAD_STATE64 0

#endif /* defined(arm64) && defined(LP64) */

库里的注释说明了在arm64e架构下需要开启_DARWIN_OPAQUE_ARM_THREAD_STATE64，开始天真的以为有__arm64__就会有__arm64e__。通过源码的调用方式修改一下属性就行了

`

uintptr_t bs_mach_framePointer(_STRUCT_MCONTEXT * const machineContext) {

#if __has_feature(ptrauth_calls)

    return machineContext->__ss.__opaque_fp;

#else

    return machineContext->__ss.__fp;

#endif

}
