Tool Options − Compiler5−27−−inlineCommand line syntax−−inlineDescriptionWith this option you instruct the compiler to inline all functions withoutthe function qualifier __noinline, regardless whether they have thekeyword inline or not. This option has the same effect as a #pragmainline at the beginning of the source file.This option can be useful to increase the possibilities for code compaction(option −Or).ExampleTo inline all functions:c<strong>pcp</strong> −−inline test.cRelated informationCompiler option −Or (Optimization: code compaction)• • • • • • • •
5−28PCP Reference Manual−−inline−max−incr /−−inline−max−sizeCommand line syntax−−inline−max−incr=percentage−−inline−max−size=thresholdDefault−−inline−max−incr=25−−inline−max−size=10DescriptionWith these options you can control the function inlining optimizationprocess of the compiler. These options have only effect when you haveenabled the inlining optimization (option −Oi).Regardless of the optimization process, the compiler always inlines allfunctions that have the function qualifier inline.TOOL OPTIONSWith the option −−inline−max−size you can specify the maximum size offunctions that the compiler inlines as part of the optimization process. Thecompiler always inlines all functions that are smaller than the specifiedthreshold. The threshold is measured in compiler internal units and thecompiler uses this measure to decide which functions are small enough toinline. The default threshold is 10.After the compiler has inlined all functions that have the function qualifierinline and all functions that are smaller than the specified threshold, thecompiler looks whether it can inline more functions without increasing thecode size too much. With the option −−inline−max−incr you can specifyhow much the code size is allowed to increase. By default, this is 35%which means that the compiler continues inlining functions until theresulting code size is 35% larger than the original size.Examplec<strong>pcp</strong> −−inline−max−incr=40 −−inline−max−size=15 test.c
