1023 characters. No relocation is created for this symbol; it will

exist purely for pulling in object files from archives. Note that

this reloc is not sufficient to prevent garbage collection; use a

KEEP() directive in the linker file to preserve such objects.

file are. This is used for validating the command line options passed to
|
|
the assembler against the options the original source file was compiled with.
|
|
The expected format is:
|
|
‘<samp>.mspabi_attribute tag_name, tag_value</samp>’
|
|
For example, to set the tag <code>OFBA_MSPABI_Tag_ISA</code> to <code>MSP430X</code>:
|
|
‘<samp>.mspabi_attribute 4, 2</samp>’

values.
