[Bug modula2/108344] Many tests time out: isatty called in a tight loop
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108344 --- Comment #7 from CVS Commits --- The releases/gcc-13 branch has been updated by Gaius Mulley : https://gcc.gnu.org/g:35a04220554d62d9bbe068dfa2f52d4d2d572805 commit r13-7636-g35a04220554d62d9bbe068dfa2f52d4d2d572805 Author: Gaius Mulley Date: Fri Jul 28 22:50:41 2023 +0100 [PATCH] PR modula2/108344 disable default opening of /dev/tty This patch changes removes the static initialisation code for KeyBoardLEDs.cc. The module is only initialised if one of the exported functions is called. This is useful as the module will access /dev/tty which might not be available. TimerHandler.mod has also been changed to disable the scroll lock LED as a sign of life. gcc/m2/ChangeLog: PR modula2/108344 * gm2-libs-coroutines/TimerHandler.mod (EnableLED): New constant. (Timer): Test EnableLED before switching on the scroll LED. libgm2/ChangeLog: PR modula2/108344 * libm2cor/KeyBoardLEDs.cc (initialize_module): New function. (SwitchScroll): Call initialize_module. (SwitchNum): Call initialize_module. (SwitchCaps): Call initialize_module. (SwitchLEDs): Call initialize_module. (M2EXPORT): Remove initialization code.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108344 Rainer Orth changed: What|Removed |Added Resolution|--- |FIXED Status|ASSIGNED|RESOLVED --- Comment #6 from Rainer Orth --- I hadn't seen those timeout for quite some time even before your patch (roughly since 20230123). So it seems whatever caused this is fixed (or at least masked).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108344 --- Comment #5 from Gaius Mulley --- On reflection I suspect it is doubtful this is the same bug. However it might reduce the timeouts when running the regression tests.
