This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

/* With some trickery we can use the code in this file for most (if
|
||
not all) ptrace(2) based SPARC systems, which includes SunOS 4,
|
||
GNU/Linux and the various SPARC BSD's.
|
||
|
||
First, we need a data structure for use with ptrace(2). SunOS has
|
||
`struct regs' and `struct fp_status' in <machine/reg.h>. BSD's
|
||
have `struct reg' and `struct fpreg' in <machine/reg.h>. GNU/Linux
|
||
has the same structures as SunOS 4, but they're in <asm/reg.h>,
|
||
which is a kernel header. As a general rule we avoid including
|
||
GNU/Linux kernel headers. Fortunately GNU/Linux has a `gregset_t'
|
||
and a `fpregset_t' that are equivalent to `struct regs' and `struct
|
||
fp_status' in <sys/ucontext.h>, which is automatically included by
|
||
<signal.h>. Settling on using the `gregset_t' and `fpregset_t'
|
||
typedefs, providing them for the other systems, therefore solves
|
||
the puzzle. */
