Hi,
If using this program, we need to define a support alias platform, is not
it? This platform needs to include the ArchType in the Triple.h file for the
most part, and we need to set the ObjectFormatType to COFF, ELF, and Wasm. But
we only want to exclude the few unsupported platforms. If my understanding is
not right, please told me.
