Interprocedural Optimization (IPO) Options

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
