[llvm-dev] Generating object files more efficiently

[J S via llvm-dev]

How do I tell clang to use my target CPU's assembler instead of my host's assembler? I found the -fuse-ld option to tell it to use my linker but didn't find an option for the assembler.
Thanks.

There's a function in lib/Driver/ToolChains/CommonArgs.cpp called tools::getCPUName that needs to be implemented for each target to determine how to process -mcpu/-march

You might be able to bypass that for testing purposes by adding "-Xclang -target-cpu -Xclang mycpu" to your driver command line.

Hi,

XYZ is your actual architecture? Are you trolling?
