1080074 - Switch win64 builds to MSVC2013

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Benjamin Smedberg]

Our nightly win64 builds are currently built using MSVC2012. We should switch them to MSVC2013. Since they are currently not riding the trains, I think we could do this immediately, or any time you are comfortable.

dmajor can you prepare the mozconfig changes for this?

Yes, this sounds reasonable. It will also be a good practice run for the win32 change.

2010, right? Unless I'm missing something...

I thought the win64 builds were 2012, but I can't remember why.

Did a sanity test to make sure the build system doesn't mind having mixed mozconfigs:

Carrying forward r=glandium since this was split off of bug 1061335.

Bug 1080297 is a last-minute regression that will need to be fixed before this can go in. (It's in the dependency tree somewhere, so I didn't bother adding it separately to this bug)

bsmedberg, is there anything else that I need to wait on before pushing?

Sanity checks:

ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2014/10/2014-10-11-03-02-03-mozilla-central/
The Win64 build log says: Microsoft (R) C/C++ Optimizing Compiler Version 18.00.30723 for x64
And the zip package contains msvcr120.dll/msvcp120.dll.

I installed the previous (VC10) Win64 nightly on a machine with no VC12 CRT, let it update, and confirmed that I get the new CRT and the new nightly loads without problems.
