dev-util/mingw64-runtime: fix build against gcc-11 (__rdtsc clash) |
9 |
|
10 |
gcc-11 defines __rdtsc as a macro: |
11 |
// include/ia32intrin.h:110 |
12 |
#define __rdtsc() __builtin_ia32_rdtsc () |
13 |
and causes build failure: |
14 |
intrincs/rdtsc.c:15:30: |
15 |
error: macro "__rdtsc" passed 1 arguments, but takes just 0 |
16 |
15 | unsigned __int64 __rdtsc(void) |
17 |
| ^ |
18 |
|
19 |
Let's avoid __rdtsc definition on systems with #define __rdtsc present. |
20 |
|
21 |
There is still a chance that it might be a '#define __rdtsc __rdtsc'. |
22 |
We'll revisit it then. |
