When runtime patching code (like e.g. done by the Linux kernel) there may be cases where the set of stack frame alterations differs between unpatched and patched code. Consequently the corresponding unwind data needs patching too. Locating the right places within an FDE, however, is rather cumbersome without a way to insert labels in the resulting section. Hence this patch introduces a new directive, .cfi_label. Note that with the way CFI data gets emitted currently (at the end of the assembly process) this can't support local FB- and dollar-labels. gas/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/dw2gencfi.c (cfi_add_label, dot_cfi_label): New. (cfi_pseudo_table): Add "cfi_label". (output_cfi_insn): Handle CFI_label. (select_cie_for_fde): Als terminate CIE when encountering CFI_label. * dw2gencfi.h (cfi_add_label): Declare. (struct cfi_insn_data): New member "sym_name". (CFI_label): New. * read.c (read_symbol_name): Drop "static". * read.h (read_symbol_name): Declare. gas/testsuite/ 2015-01-12 Jan Beulich <jbeulich@suse.com> gas/cfi/cfi-label.d, gas/cfi/cfi-label.s: New. gas/cfi/cfi.exp: Run new tests. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
