Bug ID: 104374
Summary: attributes for signal safety and signal handling
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: crrodriguez at opensuse dot org
Target Milestone: ---
It will be nice that a set of function attributes like:
__attribute__((signal_handler)) (since "signal" is already used in the AVR
port) for sa_handler function
and
__attribute__(("async-signal-safe")) --> for use with gcc builtins and the C
library to annotate functions that either ought to be signal safe according to
the standards or user defined.
SO -Wall could warn about for example using stdio on a signal handler or
similar bugs.
