TLS Examples

These are a collection of source files and a makefile to build different code patterns to generate TLS access methods.

• Global Dynamic
• Local Dynamic
• Initial Exec
• Local Exec

These examples were created in conjunction with my TLS documentation.

Building

To build just use:

# this will build using or1k-smh-linux-gnu-
make

To build with a different cross toolchain to:

# this will build using the system default toolchain
make CROSS_COMPILE=

Testing

The tls example build will also generate executable binaries which can be run and should return 0 if they work correctly. This can be used as a crude test suite for TLS handling. Using a more complete test suite like that found in glibc is recommended, but this can get you off the ground.

$ make check
$ cat test-results.out

Running tls-gd-dynamic...
ok
Running tls-ld-dynamic...
ok
Running nontls-dynamic...
ok
Running tls-le-static...
ok
Running tls-ie-static...
ok
Running nontls-static...
ok

Cleaning up

Like most makefiles we also provide a way to cleanup with clean.

make clean
