|

Assume that LD would optimize LDI32 instructions by checking the upper
|
||||
16 bits of the @var{expression}. If they are all zeros, then LD would
|
||||
shorten the LDI32 instruction to a single LDI. In such case @code{@value{AS}}

will output DIFF relocations for diff expressions.
|

|
||||
@cindex @code{mno-link-relax} command line option, PRU
|

@item -mno-link-relax
|

Assume that LD would not optimize LDI32 instructions. As a consequence,

DIFF relocations will not be emitted.
|

|

@cindex @code{mno-warn-regname-label} command line option, PRU

|

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.
