This patch changes various global target_desc declarations to const, thereby correcting a prominent source of ODR violations in PowerPC-related target code. The majority of files/changes are mechanical const-ifications accomplished by regenerating the C files in features/. This also required manually updating mips-linux-tdep.h, s390-linux-tdep.h, nios2-tdep.h, s390-tdep.h, arch/ppc-linux-tdesc.h, arch/ppc-linux-common.c, and rs6000-tdep.c. Patch tested against the sourceware trybot, and fully regression tested against our (Red Hat's) internal test infrastructure on Rawhide aarch64, s390x, x86_64, and powerpcle. With this patch, I can finally enable LTO in our GDB package builds. [Tested with a rawhide scratch build containing this patch.] Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=22395 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=24835

# 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
|
|
