Status Meeting (January 2017)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place today, 26th of January, 19:00 UTC. We skipped the last meeting because of holidays and unavailability of people. 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. Alternatively we'll do it in #reactos-meeting on Freenode, depending on our admins mood. Please send agenda proposals to me before the meeting so we don't waste time trying to setup the agenda directly during the meeting. Regards, Aleksey Bragin

MASM using longer opcode sequences than GAS

by Colin Finck

Hi all, In order to make our ISOs flashable to USB drives and bootable from them (cf. CORE-12648), I'm currently overhauling our ISO boot sector "isoboot.S". This adds a lot of code and while I stay in the 2K size limit when assembling it with GAS, I break it with MASM. Disassembling the assembled files shows the difference. A line like: mov word ptr ds:[GetlinsecPtr], ax is assembled by GAS to: A35B50 mov [0x505b],ax while MASM does this: 67A35B500000 mov [dword 0x505b],ax Is there any option to enforce the shorter opcode sequence for MASM too? The code uses a lot of similar MOVs and this seems to be the only reason why I break the 2K size limit with MASM. If there is no such option, what are the advantages of using MASM for our MSVC build anyway? Can't we just use GAS for both or decide on a common third-party assembler (NASM) for our assembly files? Cheers, Colin

Re: [ros-dev] USB from GSoC

by mvardan.dev

Hello Aleksey, About readiness to get merged I think decision should be done by Thomas or Amine. Related to collaboration with ROS, as I have informed on one of the monthly meetings, I have willing to contribute ReactOS. But for now I have probelm with time which is depend on many factors. We can schedule meeting in IRC or wherever you want, to discuss how I can help to our project. Thanks,Vardan.

What happened to the USB branch made by Vardan during GSoC 2016? Is it ready to be merged, or if not, what's holding it? Any input is appreciated, especially from Vardan himself.

Looks like they should be doing the exact same thing.

Unfortunately now you have a race condition if multiple of these functions get called concurrently.
