[Rocky] suppress -Wpsabi warning with targeted GCC version check
GCC 10.1 and later may emit a -Wpsabi warning when returning
std::pair<double, double> from a function in C++17 mode on AArch64:
kudu/src/kudu/tablet/compaction_policy.cc:304:63: note: parameter
passing for argument of type ‘std::pair<double, double>’ when C++17
is enabled changed to match C++14 in GCC 10.1
304 | std::pair<double, double> ComputeLowerAndUpperBound() const {
| ^
The affected function, ComputeLowerAndUpperBound(), is purely internal
to Kudu and not part of any public ABI. Moreover, all Kudu components
are statically linked in release builds, so ABI mismatch across
compiler versions is not a concern.
To eliminate this harmless warning while keeping the function interface
unchanged, this patch applies a targeted `#pragma GCC diagnostic ignored
"-Wpsabi"` directive, guarded by a version check: only GCC ≥ 10.1 and
< 13 will apply the suppression, and Clang is explicitly excluded.
This approach avoids unnecessary changes to return types (e.g., replacing
std::pair with a custom struct) and minimizes the risk of compiler-specific
logic spilling into unrelated builds.
Build environment:
- GCC version: 11.5.0 20240719 (Red Hat 11.5.0-5)
- ld (GNU gold) version: 1.16
No functional behavior is changed.
