@item bootstrap
|
||||
Builds GCC three times---once with the native compiler, once with the
|
||||
native-built compiler it just built, and once with the compiler it built
|
||||
the second time. In theory, the last two should produce the same
|
||||
results, which @samp{make compare} can check. Each step of this process
|
||||
is called a ``stage'', and the results of each stage @var{N}
|
||||
(@var{N} = 1@dots{}3) are copied to a subdirectory @file{stage@var{N}/}.
|
||||
The toplevel tree from which you start GCC compilation is not
|
||||
the GCC directory, but rather a complex Makefile that coordinates
|
||||
the various steps of the build, including bootstrapping the compiler
|
||||
and using the new compiler to build target libraries.
|
||||
|
||||
When GCC is configured for a native configuration, the default action
|
||||
for @command{make} is to do a full three-stage bootstrap. This means
|
||||
that GCC is built three times---once with the native compiler, once with
|
||||
the native-built compiler it just built, and once with the compiler it
|
||||
built the second time. In theory, the last two should produce the same
|
||||
results, which @samp{make compare} can check. Each stage is configured
|
||||
separately and compiled into a separate directory, to minimize problems
|
||||
due to ABI incompatibilities between the native compiler and GCC.
|
||||
|
||||
If you do a change, rebuilding will also start from the first stage
|
||||
and ``bubble'' up the change through the three stages. Each stage
|
||||
is taken from its build directory (if it had been built previously),
|
||||
rebuilt, and copied to its subdirectory. This will allow you to, for
|
||||
example, continue a bootstrap after fixing a bug which causes the
|
||||
stage2 build to crash. It does not provide as good coverage of the
|
||||
compiler as bootstrapping from scratch, but it ensures that the new
|
||||
code is syntactically correct (e.g. that you did not use GCC extensions
|
||||
by mistake), and avoids spurious bootstrap comparison
|
||||
failures@footnote{Except if the compiler was buggy and miscompiled
|
||||
some of the files that were not modified. In this case, it's best
|
||||
to use @command{make restrap}.}.
|
||||
|
||||
Other targets available from the top level include:
|
||||
|
||||
@table @code
|
||||
@item bootstrap-lean
|
||||
Like @code{bootstrap}, except that the various stages are removed once
|
||||
they're no longer needed. This saves disk space.
|
||||
|
||||
@item bubblestrap
|
||||
This incrementally rebuilds each of the three stages, one at a time.
|
||||
It does this by ``bubbling'' the stages up from their subdirectories
|
||||
(if they had been built previously), rebuilding them, and copying them
|
||||
back to their subdirectories. This will allow you to, for example,
|
||||
continue a bootstrap after fixing a bug which causes the stage2 build
|
||||
to crash.
|
||||
@item bootstrap2
|
||||
@itemx bootstrap2-lean
|
||||
Performs only the first two stages of bootstrap. Unlike a three-stage
|
||||
bootstrap, this does not perform a comparison to test that the compiler
|
||||
is running properly. Note that the disk space required by a ``lean''
|
||||
bootstrap is approximately independent of the number of stages.
|
||||
|
||||
@item quickstrap

is also termed the @file{stage0} GCC.}.
|

You will invoke this target if you need to test or debug the

|

@item stage
|

For each package that is bootstrapped, relocate its build directory
|

If you wish to use non-default GCC flags when compiling the stage2 and

|
||||
|
||||
Usually, the first stage only builds the languages that the compiler
|
||||
is written in: typically, C and maybe Ada. If you are debugging a
|
||||
miscompilation of a different stage2 front-end (for example, of the
|
||||
Fortran front-end), you may want to have front-ends for other languages
|
||||
in the first stage as well. To do so, set @code{STAGE1_LANGUAGES}
|
||||
on the command line when doing @samp{make}.
|
||||
|
||||
For example, in the aforementioned scenario of debugging a Fortran
|
||||
front-end miscompilation caused by the stage1 compiler, you may need a
|
||||
command like
|
||||
|
||||
@example
|
||||
make stage2-bubble STAGE1_LANGUAGES=c,fortran
|
||||
@end example
|
||||
|
||||
Alternatively, you can use per-language targets to build and test
|
||||
languages that are not enabled by default in stage1. For example,
|
||||
@command{make f951} will build a Fortran compiler even in the stage1
|
||||
build directory.
