gcc: Assembler Options

1 3.13 Passing Options to the Assembler
1 =====================================
1 
1 You can pass options to the assembler.
1 
1 '-Wa,OPTION'
1      Pass OPTION as an option to the assembler.  If OPTION contains
1      commas, it is split into multiple options at the commas.
1 
1 '-Xassembler OPTION'
1      Pass OPTION as an option to the assembler.  You can use this to
1      supply system-specific assembler options that GCC does not
1      recognize.
1 
1      If you want to pass an option that takes an argument, you must use
1      '-Xassembler' twice, once for the option and once for the argument.
