CHAPTER 2 OPTIONS
2.3 Notes and Evaluation When Option is Specified
When specifying options, some options need duplicated specification and some need
sequence to specify them.
In the linkage kit, the options are evaluated according to rules.
■ Notes and Evaluation When Specified Option
The precautions and rules of evaluation when specifying options are described below.
● Options that require no parameters
Specifying only once is enough. Duplicated specifications have no meaning.
[Example]
-V : Specifying the message output
Duplicated specification like -V -V has no meaning and is error-free.
● Options that require parameters
When duplicated specification is required, there are different methods of evaluation as shown below.
• Only the last specification is effective.
• The order in which the specifications appear has specific intent, and all specifications are effective.
• The order in which the specifications appear is irrelevant, and all specifications are effective.
[Example 1 Only the last option which is specified is valid]
-o file.abs :Specifying the output file
When options are specified two or more times like -o file.abs -o file.rel, the specification that is entered last
becomes effective. (In this case, file.rel becomes effective.)
[Example 2 Order of specifying options has meaning and all specifications are effective]
-l lib1.lib -l lib2.lib : Specifying the library retrieval (linker)
When options are specified in order, such as -l lib2.lib -l lib1.lib, order of retrieving library is inverted.
[Example 3 Order of specifying options has no meaning, yet all specifications are effective]
-sc CODE=0x1000 -sc DATA=0x200 : Specifying location of sections (linker)
When options are specified in order, such as -sc DATA=0x200 -sc CODE=0x1000, all options are effective
because the location of sections are individually independent.
