Derived from bug 1160137. http://ftp.mozilla.org/pub/mozilla.org/spidermonkey/try-builds/arai_a@mac.com-5021b3857357/try-win64/try_win64_spidermonkey-compacting-bm79-try1-build2.txt.gz > checking host system type... i686-pc-mingw32 > checking target system type... i686-pc-mingw32 > checking build system type... i686-pc-mingw32 that seems to be the reason why we get "error C2118: negative subscript" in opt build. we should pass --target=x86_64-pc-mingw32 and --host=x86_64-pc-mingw32 from autospider.sh.

Try is running: https://treeherder.mozilla.org/#/jobs?repo=try&revision=95e8d0c02f82&exclusion_profile=false at least it passes plain builds both with opt and debug.

Just added "--target=x86_64-pc-mingw32 --host=x86_64-pc-mingw32" to configure args for msys with win64. Green on try run: https://treeherder.mozilla.org/#/jobs?repo=try&revision=95e8d0c02f82&exclusion_profile=false This also needs the patch for bug 1160137 to make it work with debug build (win64-debug)

Comment on attachment 8600317 [details] [diff] [review] Set target to x86_64 for spidermonkey shell build on Windows 8 x64. Review of attachment 8600317 [details] [diff] [review]: ----------------------------------------------------------------- Sounds good to me. Thanks! (I never did look closely at the win64 builds to see if they were doing something sensible.)
