Tim Armstrong created IMPALA-6299:
-------------------------------------
Summary: IRBuilder codegen should using LLVMCodeGen::cpu_attrs
instead of CpuInfo to determine valid instructions
Key: IMPALA-6299
URL: https://issues.apache.org/jira/browse/IMPALA-6299
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
This came out of a discussion on this code review:
https://gerrit.cloudera.org/#/c/8802/
The idea is that IRBuilder code that emits intrinsics should only do so if we
have those CPU features enabled in LLVM. Otherwise codegen will fail to compile
the emitted instructions.
