Doug Rabson	294156a7ff	* Move exception_return to exception.s which is a more logical home for it. ... * Optimise the return path for syscalls so that they only restore a minimal set of registers instead of performing a full exception_return. A new flag in the trapframe indicates that the frame only holds partial state. When it is necessary to perform a full state restore (e.g. after an execve or signal), the flag is cleared to force a full restore.	2001-02-02 10:20:30 +00:00

Doug Rabson	eae8e50443	Add sc_traparg_a0, sc_traparg_a1 and sc_traparg_a2 to the sigcontext ... structure for the alpha. These give extra information about some signals (such as SIGSEGV) and should be compatible with Digital Unix. Submitted by: jdp	1998-11-18 23:51:40 +00:00
John Birrell	7fed2e3a32	These are a few of the alpha machine dependent header files - the first ... referenced by the build of user-space libraries. These files were obtained from NetBSD (with ansi.h being modified to reflect the FreeBSD off_t and pid_t implementation).	1998-01-10 10:13:16 +00:00
