However, if the compiler does not find any references to the extern symbolin the C module, it optimizes the assembly source by leaving the .EXTRN directive out.With this pragma you can force an external reference (.EXTRN assembler directive), even when thesymbol is not used in the module.inline / noinline / smartinline [default | restore] (*)See Section 1.10.4, Inlining Functions: inline.inline_max_incr {value | default | restore} (*)inline_max_size {value | default | restore} (*)With these pragmas you can control the automatic function inlining optimization process of the compiler.It has effect only when you have enabled the inlining optimization (C compiler option --optimize=+inline).See C compiler options --inline-max-incr / --inline-max-size.linear_switch / jump_switch / binary_switch / smart_switch [default |restore] (*)With these pragmas you can overrule the compiler chosen switch method:linear_switchjump_switchforce jump chain code. A jump chain is comparable with an if/else-if/else-if/elseconstruction.force jump table code. A jump table is a table filled with jump instructions for eachpossible switch value. The switch argument is used as an index to jump within thistable.24
