Arguments
None
Default
-fjump-tables
The compiler may use jump tables for switch statements.
Description
This option determines whether jump tables are generated for switch statements.
Option
-fno-jump-tables
prevents the compiler from generating jump tables for switch statements. This action is performed unconditionally and independent of any generated code performance consideration.
Option
-fno-jump-tables
also prevents the compiler from creating switch statements internally as a result of optimizations.
Use
-fno-jump-tables
with
-fpic
when compiling objects that will be loaded in a way where the jump table relocation cannot be resolved.
Alternate Options
None
