While reviewing the enum gdb_syscall entries with values >= 500, I noticed that gdb_sys_accept exists, but gdb_sys_accept4 doesn't, while recording support is essentially the same, given that the difference in interface is only an extra int parameter: ... int accept (int sockfd, struct sockaddr *addr, socklen_t *addrlen); int accept4 (int sockfd, struct sockaddr *addr, socklen_t *addrlen, int flags); ... Fix this by: - adding gdb_sys_accept4, - supporting it in record_linux_system_call alongside gdb_sys_accept, and - mapping to gdb_sys_accept4 in various syscall canonicalization functions. The usual thing to do before the rewrite of i386_canonicalize_syscall would have been to use the value from arch/x86/entry/syscalls/syscall_32.tbl: ... gdb_sys_accept4 = 364, ... but that's no longer necessary, so instead we use some >= 500 value: ... gdb_sys_accept4 = 533, ... to steer clear of the space where ppc_canonicalize_syscall and s390_canonicalize_syscall do hard-coded number magic. Tested on x86_64-linux, with and without target board unix/-m32, and aarch64-linux. Approved-By: Guinevere Larsen <guinevere@redhat.com>
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.
