Параметры подробно (Options detail)
Solaris 2
These -m
options are supported on Solaris 2:
-mclear-hwcap
-mclear-hwcap
tells the compiler to remove the hardware
capabilities generated by the Solaris assembler. This is
only necessary when object files use ISA extensions not
supported by the current machine, but check at runtime
whether or not to use them.
-mimpure-text
-mimpure-text
, used in addition to -shared
, tells the
compiler to not pass -z text
to the linker when linking a
shared object. Using this option, you can link position-
dependent code into a shared object.
-mimpure-text
suppresses the "relocations remain against
allocatable but non-writable sections" linker error message.
However, the necessary relocations trigger copy-on-write, and
the shared object is not actually shared across processes.
Instead of using -mimpure-text
, you should compile all source
code with -fpic
or -fPIC
.
These switches are supported in addition to the above on Solaris
2:
-pthreads
This is a synonym for -pthread
.
