Hi All,
this patch fixes a mismatch in ucontext struct between uClibc and kernel.
In this way a signal handler installed by sigaction can access
to the whole machine state correctly.
This can be applied both to trunk and nptl branch
/* Context to describe whole processor state. */
typedef struct
{
+ unsigned int oldmask;
+
+ /* CPU registers */
gregset_t gregs;
+ unsigned int pc;
+ unsigned int pr;
+ unsigned int sr;
+ unsigned int gbr;
+ unsigned int mach;
+ unsigned int macl;
+
+#ifdef __CONFIG_SH4__
+ /* FPU registers */
fpregset_t fpregs;
fpregset_t xfpregs;
unsigned int fpscr;
unsigned int fpul;
- unsigned int macl;
- unsigned int mach;
+ unsigned int ownedfp;
+#endif
} mcontext_t;
/* Userlevel context. */
