|GNU Compiler Collection (GCC) Internals|
Here we spell out what files will be set up by configure in the gcc directory. Some other files are created as temporary files in the configuration process, and are not used in the subsequent build; these are not documented.
outputs, then the files listed in
outputsthere are also generated.
The following configuration headers are created from the Makefile,
using mkconfig.sh, rather than directly by configure.
config.h, bconfig.h and tconfig.h all contain the
xm-machine.h header, if any, appropriate to the host,
build and target machines respectively, the configuration headers for
the target, and some definitions; for the host and build machines,
these include the autoconfigured headers generated by
configure. The other configuration headers are determined by
config.gcc. They also contain the typedefs for
#ifdef TREE_CODEconditional code segements. The machine-protos.h is included after the rtl.h and/or tree.h would have been included. The tm_p.h also includes the header tm-preds.h which is generated by genpreds program during the build to define the declarations and inline functions for the predicate functions.
