9.36.1 Options

-mlink-relax
Assume that LD would optimize LDI32 instructions by checking the upper 16 bits of the expression . If they are all zeros, then LD would shorten the LDI32 instruction to a single LDI. In such case as will output DIFF relocations for diff expressions.


-mno-link-relax
Assume that LD would not optimize LDI32 instructions. As a consequence, DIFF relocations will not be emitted.


-mno-warn-regname-label
Do not warn if a label name matches a register name. Usually assembler programmers will want this warning to be emitted. C compilers may want to turn this off.
