它是安全与armeabi-V7A-难以替代armeabi,V7A? [英] is it safe to replace armeabi-v7a with armeabi-v7a-hard?
问题描述
我是想支持armeabi-V7A所有的设备应该能够支持armeabi-V7A硬。如果是这样,为什么我们不放弃armeabi-V7A或只使用armeabi-V7A-难以替代armeabi-V7A为NDK的> = XX(9C?)
i am think that all device that support armeabi-v7a should be able to support armeabi-v7a-hard. if so, why do not we just abandon armeabi-v7a or just use armeabi-v7a-hard to replace armeabi-v7a for NDK that >=xx(9c?)
推荐答案
-msoft流通和-mhard浮动并不硬件和软件浮点之间切换。
-msoft-float and -mhard-float do not toggle between hardware and software floating point.
实际的区别是如何将参数传递给函数的调用约定。
The actual difference is the calling convention on how arguments are passed to functions.
这意味着,-mhard浮动只是稍快(都使用硬件浮点实现),但-msoft浮球具有更好的兼容性ABI
This means that -mhard-float is only slightly faster (both use hardware floating point implementation), but -msoft-float has better ABI compatibility.
