Re: [ros-dev] [ros-diffs] [tfaber] 62266: [CRT] - Force the use of memory operands in bit test intrinsics. Bit offsets above 31 (or 63) can't behave correctly with registers (the constant case is fine because it ensures low...

by Timo Kreuzer

While the bug was definately on our side, I still think there is a GCC/CLANG bug here as well. Memory operands larger than register size are a rare case (probably limited to the bittest instructions) but allowing a register operand here should cause the compiler to either error out or in the worst case emit something like "mov eax, [BaseAddress]; bt eax, cl;" or "mov eax, [PointerToBaseAddress]; mov eax, [eax]; bt eax, cl;" rather than "bt [PointerToBaseAddress], cl;", which it actually did. Changing the constraint to something that wasn't working changed the behaviour in a way that changed the level of dereference! The operation was done on the pointer instead of on the memory pointed to by the pointer! Maybe we should file a bugreport.

Server fixes

by Colin Finck

Hi all, Pierre and me changed the HTTP server software on the VM for build.reactos.org, git.reactos.org, source.reactos.org and svn.reactos.org today. This may or may not fix the performance issues people were recently experiencing at git.reactos.org. At least, the stability has improved and the full configuration is less complex, making further changes easier. If anything got noticably worse, please report here. Cheers, Colin

Status Meeting (January 2014)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place last Thursday of this month, 30th of January, 19:00 UTC. Put that into your calendars so you don't forget. And that's in two days! IRC service will only be started shortly before the meeting. Your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. If someone still is not getting passwords sent before a meeting - please email Pierre before the meeting started to get one. The agenda will be posted shortly before the meeting, suggestions are welcome (send them to me shortly before the meeting starts). Hermes sent the first suggestion well before the meeting, so please follow his example and send your suggestions too. Regards, Aleksey Bragin
