#### Build Factory ####
#######################
## This is where our Build Factory is defined. A build factory is a
## description of the build process, which is made in terms of build
## steps. The BuildAndTestGDBFactory is the main build factory for
## GDB; it is configurable and should be more than enough to describe
## most builds.
class BuildAndTestGDBFactory (factory.BuildFactory):
"""This is the main build factory for the GDB project. It was made to
be very configurable, and should be enough to describe most builds.
The parameters of the class are:
- ConfigureClass: set this to be the class (i.e., build step) that
will be called to configure GDB. It needs to accept the same
arguments as the ConfigureGDB class above. The default is to
use ConfigureGDB.
- CompileClass: set this to be the class (i.e., build step) that
will be called to compile GDB. It needs to accept the same
arguments as the CompileGDB class above. The default is to use
CompileGDB.
- TestClass: set this to be the class (i.e., build step) that will
be called to test GDB. It needs to accept the same arguments as
the TestGDB class above. The default is to use TestGDB.
- extra_conf_flags: extra flags to be passed to "configure".
Should be a list (i.e., []). The default is None.
- enable_targets_all: set this to True to pass
'--enable-targets=all' to configure. The default is True.
- extra_make_flags: extra flags to be passed to "make", when
compiling. Should be a list (i.e., []). The default is None.
- extra_make_check_flags: extra flags to be passed to "make
check", when testing. Should be a list (i.e., []). The default
is None.
- test_env: extra environment variables to be passed to "make
check", when testing. Should be a dictionary (i.e., {}). The
default is None.
- test_parallel: set to True if the test shall be parallelized.
Default is False. Beware that parallelizing tests may cause
some failures due to limited system resources.
- make_command: set the command that will be called when running
'make'. This is needed because BSD systems need to run 'gmake'
instead of make. Default is 'make'.
- use_system_debuginfo: set to False if GDB should be compiled
with the "--with-separate-debug-dir" option set to
"/usr/lib/debug". Default is True.

#### Builders ####
##################
## This section describes our builders. The builders are instances of
## a build factory, and they will be used to do a specific build of
## the project.
##
## The nomenclature here is important. Every builder should start
## with the prefix "RunTestGDB", and then be followed by the testing
## scenario that the build will test, followed by "_cXXtYY", where XX
## is the bitness of the compilation, and YY is the bitness of the
## testing. So, for example, if we are specifically testing GDB
## running the native-gdbserver tests, compiling GDB on a 64-bit
## machine, but running the tests in 32-bit mode, our builder would be called:
