5.7.7.21 Inline-limit Option

The -finline-limit=n option controls the inlining size limit for functions marked inline. The argument, n, is a number of pseudo instructions (not counting parameter handling) being an abstract measurement of a function's size. In no way does this value represent a count of assembly instructions and as such, its exact meaning might change from one release of the compiler to an another. The default value of n is 10000.

Increasing the inlining limit can result in more inlined code at the cost of compilation time and memory consumption.
