Subject: [PATCH] source/test/testharness.h: don't redefine `__rdtsc()` builtin
|
|
|
|
On darwin clang-16 provides `__rdtsc()` builtin. As a result the build
|
|
fails in `nixpkgs` as:
|
|
|
|
source/test/testharness.h:78:24: error: static declaration of '__rdtsc' follows non-static declaration
|
|
static inline uint32_t __rdtsc(void)
|
|
^
|
|
x265_3.6/source/test/testharness.h:78:24: note: '__rdtsc' is a builtin with type 2
|
|
|
|
The change avoid redefinition on targets that define `__rdtsc()` builtin.
