@section Build Script
@cindex build script
The script @file{gdb_buildall.sh} builds @value{GDBN} with flag
@option{--enable-targets=all} set. This builds @value{GDBN} with all supported
targets activated. This helps testing @value{GDBN} when doing changes that
affect more than one architecture and is much faster than using
@file{gdb_mbuild.sh}.
After building @value{GDBN} the script checks which architectures are
supported and then switches the current architecture to each of those to get
information about the architecture. The test results are stored in log files
in the directory the script was called from.
