Can you explain the context of this change? Are you testing on a
target which matches *-*-linux* *-*-gnu* *-*-uclinux* but does not
support 'alarm'?
I was looking at backporting this and a later patch from Torbjorn to
gcc-14, but I noticed that the default dg-do-what in this directory is
'compile' and the previous
dg-do run { target *-*-linux* *-*-gnu* *-*-uclinux* } changed it to
'run' on linux targets (thus on linux we had 2 PASS, one for
compilation, one for execution).
And the test was skipped on non-linux targets.
After your patch, the test became compile-only on linux, was this intentional?
Maybe we should use instead:
/* { dg-do run } */ (without target selector)
/* { dg-require-effective-target signal } */
not tested, but I think this would restore the previous behaviour on
*linux* targets, but skip the test on targets which do not support
alarm.
Am I missing something?
I can send a patch to do this.
Thanks,
Christophe
