This commit adds target description support for Alpha. The target description obviates the alpha_register_type and alpha_register_name functions in alpha-tdep.c. Removal of alpha_register_reggroup_p was considered but ultimately abandoned, because the "info regs" command would no longer omit the zero, fpcr, and unique registers from its output (they are neither vector nor float types). Register types in the target description annex match the types that the alpha_register_type function returned. The locally defined register_names array was moved out of alpha_register_name and renamed to alpha_register_names as a static global; calls to alpha_register_name have been replaced with direct access of the array. The patch follows the code pattern outlined in the following GDB Internals Wiki entry: https://sourceware.org/gdb/wiki/Internals%20Adding-Target-Described-Register-Support Reviewed-By: Eli Zaretskii <eliz@gnu.org> Approved-By: Simon Marchi <simon.marchi@efficios.com> Change-Id: If4b25a891228388519074a31a682e33358c71063

# This Makefile updates files in ../regformats from their XML master
|
|
# copies. Because this relies on xsltproc, it is not normally run
|
|
# during the build process; it should be run by hand when one of the
|
|
# affected XML files is changed, and the results should be kept in the
|
|
# GDB repository.
|
|
|
|
# It can also update the C files in the features directory from their
|
|
# XML master copies. This relies on a GDB linked with expat and that
|
|
# is configured to include support for the architecture, so the files
|
|
# are kept in the GDB repository.
|
|
#
|
|
# By default we'll generate all C files, and you must point make at a
|
|
# GDB that has been configured with --enable-targets=all:
|
|
#
|
|
# make GDB=/path/to/gdb cfiles
|
|
#
|
|
# To regenerate all C files from scratch:
|
|
#
|
|
# make GDB=/path/to/gdb clean-cfiles cfiles
|
|
#
|
|
# To generate specific C files, you can override the XMLTOC and
|
|
# FEATURE_XMLFILES make variables:
|
|
#
|
|
# make GDB=/path/to/gdb XMLTOC="xml files" FEATURE_XMLFILES="xml files" cfiles
|
|
