Clément Chigot 0c223b02b6 cmd: add -maix32 to gcc calls for aix/ppc
As gcc might now be compiled in 64bit, -maix32 must always be added
to ensure that created objects will be 32bit.

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.

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.
