Optimization Options
- falias
Determines whether aliasing should be assumed in the program.
- fast
Maximizes speed across the entire program.
- fbuiltin, Oi
Enables or disables inline expansion of intrinsic functions.
- ffnalias
Specifies that aliasing should be assumed within functions.
- ffunction-sections
Places each function in its own COMDAT section.
- Gf
Enables read/write string-pooling optimization. This is a deprecated option.
- GF
Enables read-only string-pooling optimization.
- nolib-inline
Disables inline expansion of standard library or intrinsic functions.
- O
Specifies the code optimization for applications.
- Oa
Tells the compiler to assume there is no aliasing.
- Od
Disables all optimizations.
- Os
Enables optimizations that do not increase code size and produces smaller code size than O2.
- Ot
Enables all speed optimizations.
- Ow
Tells the compiler to assume there is no cross-function aliasing.
- Ox
Enables maximum optimizations.
