--------------------------------
Summary: Add bswap support for RISC-V
Key: HADOOP-19616
URL: https://issues.apache.org/jira/browse/HADOOP-19616
Project: Hadoop Common
Issue Type: Improvement
Components: native
Affects Versions: 3.4.1, 3.3.0
Reporter: Lei Wen
*Problem*
While building Hadoop native code on the riscv64 architecture, the build fails
due to missing support for bswap operations. The standard implementation relies
on compiler intrinsics or platform-specific assembly which are not defined for
RISC-V targets.
This results in compilation errors such as:
* Error: unrecognized opcode `bswap a4'
* Error: unrecognized opcode `bswap a3'
*Resolution*
Add bswap support for RISC-V.
