This document describes how to emit target llvm code for cross compilation in Impala. |
For cross compilation, Impala supports flags to specify the target triple and target cpu:
impala --emit-llvm --host-triple aarch64-unknown-linux-gnu --host-cpu cortex-a53
In addition, individual target features can be enabled/disabled:
impala --emit-llvm --host-triple aarch64-unknown-linux-gnu --host-cpu cortex-a53 --host-attr +crc,+crypto,+fp-armv8,+neon,+sve,+sve2
Target features are only considered if the target triple and target cpu are also specified.
Using the CMake support from AnyDSL, the --host-triple, --host-cpu, and --host-attr flags can be passed via IMPALA_FLAGS to the anydsl_runtime_wrap function.
