+-- Make a careful study of all signals available under the OS, to see which
+-- need to be reserved, kept always unmasked, or kept always unmasked. Be on
+-- the lookout for special signals that may be used by the thread library.
+
+-- Since this is a multi target file, the signal <-> exception mapping
+-- is simple minded. If you need a more precise and target specific
+-- signal handling, create a new s-intman.adb that will fit your needs.
+
+-- This file assumes that:
+
+-- SIGFPE, SIGILL, SIGSEGV and SIGBUS exist. They are mapped as follows:
+-- SIGPFE => Constraint_Error
+-- SIGILL => Program_Error
+-- SIGSEGV => Storage_Error
+-- SIGBUS => Storage_Error
+
+-- SIGINT exists and will be kept unmasked unless the pragma
+-- Unreserve_All_Interrupts is specified anywhere in the application.
+
+-- System.OS_Interface contains the following:
+-- SIGADAABORT: the signal that will be used to abort tasks.
+-- Unmasked: the OS specific set of signals that should be unmasked in
+-- all the threads. SIGADAABORT is unmasked by
+-- default
+-- Reserved: the OS specific set of signals that are reserved.

+ and state where to find the registers as offsets from there.
+
+ We support stubs for VxWorks and Android, providing unwind info for

+ point or altivec registers as well at some point.
+
+ For Android it would be simpler to write this in Asm since there's only
+ one variant, but to keep it looking like the VxWorks stubs,
+ C is the choice for our toplevel interface.
+
+ Note that the registers we "restore" here are those to which we have
+ direct access through the system sigcontext structure, which includes
+ only a partial set of the non-volatiles ABI-wise. */
