any document about compiler？

is there any issue about the compiler ? i wish to change the memory layout , and add some other tag(just as .keep.uvisor.cfgtbl) . and how to generate '.link_script.ld' in build file ?

Start by locating the build file and the rule that generates `.link_script.ld`; then trace how the compiler and linker inputs define the memory layout. Review the requested `.keep.uvisor.cfgtbl` tag and determine the intended generated output. Done means the desired layout and tag behavior are specified and the build reliably produces `.link_script.ld`.
