The if statement in case gdb_sys_ioctl in function
record_linux_system_call in file gdb/linux-record.c is as follows:
if (tmpulongest == tdep->ioctl_FIOCLEX
|| tmpulongest == tdep->ioctl_FIONCLEX
....
|| tmpulongest == tdep->ioctl_TCSETSW
...
}
The PowerPC ioctl value for ioctl_TCSETW is 0x802c7415. The variable
ioctl_TCSETW is defined in gdb/linux-record.h as an int. The TCSETW value
has the MSB set to one so it is a negative integer. The comparison of the
unsigned long value tmpulongest to a negative integer value for
ioctl_TCSETSW fails.
This patch changes the declarations for the ioctl_* values in struct
linux_record_tdep to unsigned long to fix the comparisons between
tmpulongest and the tdep->ioctl_* values.
An additional test gdb.reverse/test_ioctl_TCSETSW.exp is added to verify
the gdb record_linux_system_call() if statement for the ioctl TCSETSW
succeeds.
This patch has been tested on Power 10 and Intel with no test failures.
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.
