-
- The SDA consists of sections .sdata, .sbss, and .scommon.
- .scommon isn't a real section, symbols in it have their section index
- set to SHN_M32R_SCOMMON, though support for it exists in the linker script.
-
- Two switches control the SDA:
-
- -G NNN - specifies the maximum size of variable to go in the SDA
-
- -msdata=foo - specifies how such variables are handled
-
- -msdata=none - small data area is disabled
-
- -msdata=sdata - small data goes in the SDA, special code isn't
- generated to use it, and special relocs aren't
- generated
-
- -msdata=use - small data goes in the SDA, special code is generated
- to use the SDA and special relocs are generated
-
- The SDA is not multilib'd, it isn't necessary.
- MULTILIB_EXTRA_OPTS is set in tmake_file to -msdata=sdata so multilib'd
- libraries have small data in .sdata/SHN_M32R_SCOMMON so programs that use
- -msdata=use will successfully link with them (references in header files
- will cause the compiler to emit code that refers to library objects in
- .data). ??? There can be a problem if the user passes a -G value greater
- than the default and a library object in a header file is that size.
- The default is 8 so this should be rare - if it occurs the user
- is required to rebuild the libraries or use a smaller value for -G. */
