Inlining Options

This section contains descriptions for compiler options that pertain to inlining.

• fgnu89-inline
  Tells the compiler to use C89 semantics for inline functions when in C99 mode.
• finline
  Tells the compiler to inline functions declared with __inline and perform C++ inlining.
• finline-functions
  Enables function inlining for single file compilation.
• finline-limit
  Lets you specify the maximum size of a function to be inlined.
• inline-calloc, Qinline-calloc
  Tells the compiler to inline calls to calloc() as calls to malloc() and memset().
• inline-factor, Qinline-factor
  Specifies the percentage multiplier that should be applied to all inlining options that define upper limits.
• inline-forceinline, Qinline-forceinline
  Instructs the compiler to force inlining of functions suggested for inlining whenever the compiler is capable doing so.
• inline-level, Ob
  Specifies the level of inline function expansion.
• inline-max-per-compile, Qinline-max-per-compile
  Specifies the maximum number of times inlining may be applied to an entire compilation unit.
• inline-max-per-routine, Qinline-max-per-routine
  Specifies the maximum number of times the inliner may inline into a particular routine.
• inline-max-size, Qinline-max-size
  Specifies the lower limit for the size of what the inliner considers to be a large routine.
• inline-max-total-size, Qinline-max-total-size
  Specifies how much larger a routine can normally grow when inline expansion is performed.
• inline-min-caller-growth, Qinline-min-caller-growth
  Lets you specify a function size n for which functions of size <= n do not contribute to the estimated growth of the caller when inlined.
• inline-min-size, Qinline-min-size
  Specifies the upper limit for the size of what the inliner considers to be a small routine.
• Qinline-dllimport
  Determines whether dllimport functions are inlined.
