-Subject: libbpf: Handle GCC built-in types for Arm NEON
-
-From: Jean-Philippe Brucker <jean-philippe@linaro.org>
-
-[ Upstream commit 702eddc77a905782083b14ccd05b23840675fd18 ]
-
-When building Arm NEON (SIMD) code from lib/raid6/neon.uc, GCC emits
-DWARF information using a base type "__Poly8_t", which is internal to
-GCC and not recognized by Clang. This causes build failures when
-building with Clang a vmlinux.h generated from an arm64 kernel that was
-built with GCC.
-
- vmlinux.h:47284:9: error: unknown type name '__Poly8_t'
- typedef __Poly8_t poly8x16_t[16];
- ^~~~~~~~~
-
-The polyX_t types are defined as unsigned integers in the "Arm C
-Language Extension" document (101028_Q220_00_en). Emit typedefs based on
-standard integer types for the GCC internal types, similar to those
-emitted by Clang.
-
-Including linux/kernel.h to use ARRAY_SIZE() incidentally redefined
-max(), causing a build bug due to different types, hence the seemingly
-unrelated change.
