Subject: [PATCH 1/2] graphene-config: Enable NEON for AArch64 on Linux
|
||||||
|
|
||||||
|
NEON is fully supported by AArch64. However, GCC doesn't seem to define
|
||||||
|
__ARM_NEON__ or _M_ARM64 for AArch64.
|
||||||
|
|
||||||
|
Using __aarch64__ should allow a proper detection of this case.

Subject: [PATCH 2/2] meson: Fix detection of AArch64 on Linux
|
||||||
|
|
||||||
|
Neither __ARM_EABI__ nor __ARM_NEON__ are defined by GCC for AArch64,
|
||||||
|
and -mfpu=neon is not required as NEON is always supported in AArch64.
