/builds/worker/fetches/clang/lib/clang/17/include/arm_sve.h(270,1): error: cannot mangle this built-in __SVInt8_t type yet
The current clang version on Windows 2012 AArch64 CI does not support the SVInt8_t type [1], while all other AArch64 platforms can do so by adding sve cflags [2]. This failure has been observed in bug 1880814, which renders the latest libvpx not fully functional in Gecko on Windows AArch64.

In bug 1880814, the sve files will be excluded [1, 2] from the win/aarch64 build in moz.build for now. Once this bug is resolved, the changes made to remove sve files will need to be reverted.
