See ../README. This is the runtime support library for the Go programming language. This library is intended for use with the Go frontend. This library should not be stripped when it is installed. Go code relies on being able to look up file/line information, which comes from the debugging info using the libbacktrace library. The library has only been tested on GNU/Linux using glibc, and on Solaris. It should not be difficult to port to other operating systems. Directories: go A copy of the Go library from http://golang.org/, with several changes for gccgo. runtime Runtime functions, written in C, which are called directly by the compiler or by the library.

If the copyright holder for your code has already completed the agreement in connection with another Google open source project, it does not need to be completed again. Debugging ========= This describes how to test libgo when built as part of gccgo. To test a specific package, cd to the libgo build directory (TARGET/libgo) and run `make PKG/check`. For example, `make bytes/check`. To see the exact commands that it runs, including how the compiler is invoked, run `make GOTESTFLAGS=--trace bytes/check`. This will display the commands if the test fails. If the test passes, the commands and other output will be visible in a file named check-testlog in a subdirectory with the name of the package being checked. In the case of bytes/check, this will create bytes/check-testlog. To leave the test program behind, run `make GOTESTFLAGS=--keep bytes/check`. That will leave a gotestNNNN/test directory in the libgo build directory. In that directory you can run `LD_LIBRARY_PATH=../../.libs ./a.out -test.short` to run the tests. You can run specific failing tests using a -test.run option. You can see the tests being run with the -test.v option. You can run the program under a debugger such as gdb.
