-frwpi-lowering, -fno-rwpi-lowering

1.27 -frwpi-lowering, -fno-rwpi-lowering

Enables or disables runtime static initialization when generating Read-Write Position-Independent (RWPI) code.

If you compile with -frwpi-lowering, then the static initialization is done at runtime by the C++ constructor mechanism for both C and C++ code. This enables these static initializations to work with RWPI code.

Default

The default is -fno-rwpi-lowering. If -frwpi is used, then the default is -frwpi-lowering.
