/* 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. */
