| Description: |
None of gcc version egcs-2.91.66 (egcs-1.1.2 release) gcc version 2.95.3 gcc version 3.2.3 will tolerate the new -Wno-strict-aliasing option. They all currently fail to compile the HEAD. Change the option to -fno-strict-aliasing (which rmax claims is preferred) and all of them are happy again. | |||

Logged In: YES user_id=72656 As new code is added, this is constantly something to watch for. I'm closing this to allow other specific reports to be opened. dgp added on 2004-09-09 21:44:40: Logged In: YES user_id=80530 status? hobbs added on 2004-07-20 07:15:16: Logged In: YES user_id=72656 this has been applied to Tcl/Tk-8.4 and Tk-8.5. Tcl 8.5 was type-pune safe, but some new changes in Tcl 8.5 need more corrections. dgp added on 2004-03-20 02:17:35: Logged In: YES user_id=80530 rmax can close this when he's satisfied the HEAD is working again. rmax added on 2004-03-19 01:39:00: File Added - 80563: gcc3.3-strict-aliasing.patch Logged In: YES user_id=124643 The attached patch fixes the 11 warnings I got when I compiled HEAD with gcc-3.3.3 today. 8 of them were related to TclpTime_t which is unneeded and will be removed by this patch. The other three warnings are being worked around by using temporary pointers instead of passing addresses to the respective functions directly. I guess, that most optimizers are able eliminate this temporaries, so it won't affect performance, but they are not in performance-critical sections anyways. | |||
