Description Christopher Yeleighton 2023-06-22 08:18:28 UTC 
The documentation for Macro: int SIGILL in 24.2.1 Program Error Signals contains the following outdated claim:

>  Since the C compiler generates only valid instructions, ‘SIGILL’ typically indicates that the executable file is corrupted, or that you are trying to execute data.

Unfortunately, this assurance is not true any more. The text should be fixed in the following way:

‘SIGILL’ typically indicates that the executable file has been compiled for a newer machine than the one the code is being executed on.  It may also mean that that the executable file is corrupted, or you are trying to execute data.

"Signal illegal"
The SIGILL signal is sent to a process when it attempts to execute an illegal, malformed, unknown, or privileged instruction.
