Some notes on Sparc assembler

A Sparc assembler kernel should contain the following CPP lines at the beginning of the file:

#ifndef ATL_GAS_SPARC
 #error "This kernel requires gas SPARC assembler!"
#endif

This quick error exit keeps a non-SPARC assembler from generating hundreds or thousands of spurious error messages during install.
