/*
|
||||
* MESA: buffer_handle_t is defined by all Mesa builds, even if
|
||||
* one is building for a non-Android target. This avoids unnecessary
|
||||
* conditionals in driver code.
|
||||
*
|
||||
* We don't need to define buffer_handle_t locally when (__ANDROID__)
|
||||
* or ANDROID are set. Here's the distinction between the two:
|
||||
*
|
||||
* - AOSP always defines ANDROID, since it just means one is using the
|
||||
* AOSP tree. It means the build environment is Android, roughly.
|
||||
* - __ANDROID__ is defined by the toolchain. This typically means the
|
||||
* build target is Android.
|
||||
*
|
||||
* If the build environment is Android, AOSP can provide common Android
|
||||
* headers, such as <cutils/native_handle.h>. This allows one to build
|
||||
* and test certain aspects of Android window system code, on the host
|
||||
* system rather the build target.
