I Options

I
Specifies an additional directory for the include path.
i-dynamic
This is a deprecated option. It's replacement is shared-intel.
i-static
This is a deprecated option. Its replacement is static-intel.
i2, i4, i8
These are alternate option names for option integer-size.
idirafter
Adds a directory to the second include file search path.
iface
Specifies the default calling convention and argument-passing convention for an application.
implicitnone
This is an alternate option name for option -warn declarations.
include
This is an alternate option name for option I.
inline
Specifies the level of inline function expansion.
inline-debug-info, Qinline-debug-info
Produces enhanced source position information for inlined code. This is a deprecated option.
inline-factor, Qinline-factor
Specifies the percentage multiplier that should be applied to all inlining options that define upper limits.
inline-forceinline, Qinline-forceinline
Specifies that an inline routine should be inlined whenever the compiler can do 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-size, Qinline-min-size
Specifies the upper limit for the size of what the inliner considers to be a small routine.
intconstant
Tells the compiler to use FORTRAN 77 semantics to determine the kind parameter for integer constants.
integer-size
Specifies the default KIND for integer and logical variables.
ip, Qip
Determines whether additional interprocedural optimizations for single-file compilation are enabled.
ip-no-inlining, Qip-no-inlining
Disables full and partial inlining enabled by interprocedural optimization options.
ip-no-pinlining, Qip-no-pinlining
Disables partial inlining enabled by interprocedural optimization options.
ipo, Qipo
Enables interprocedural optimization between files.
ipo-c, Qipo-c
Tells the compiler to optimize across multiple files and generate a single object file.
ipo-jobs, Qipo-jobs
Specifies the number of commands (jobs) to be executed simultaneously during the link phase of Interprocedural Optimization (IPO).
ipo-S, Qipo-S
Tells the compiler to optimize across multiple files and generate a single assembly file.
ipo-separate, Qipo-separate
Tells the compiler to generate one object file for every source file.
isystem
Specifies a directory to add to the start of the system include path.
