I have a Clang-based tool I wrote for static analysis. It works fine for x86 and ARM configurations. But I also have a compilation database using the E3950 processor. Any code I run through the tool gives me: “error: unsupported argument ‘atom’ to option ‘-march=’”. Note the argument -march=atom is part of the compile_commands.json file. The tool also does not appear to recognize registers for the E3950 in asm() instructions. Any idea what is going on here? My understanding is that Clang does support the E3950.
Note that I build this tool outside the clang-tools tree with my own Makefile. I’ve been doing this since Clang version 5.
