LDC only compiles with /LARGEADDRESSAWARE:NO on Win64

[dymk]

This makes it impossible to use of 2gb of memory, which is very unfortunate given one of the main reasons for compiling 64 bit is to be able to use more than the 32 bit address space.

I've tried passing the flag -L"/LARGEADDRESSAWARE" and -L"-LARGEADDRESSAWARE", however LDC turns the first into a file to link with, and the second into a /LIBPATH argument, so I've had no luck overriding by passing in an additional flag.

Is there a way to get around this limitation?

The Wiki page at http://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC says that /LARGEADDRESSAWARE:NO is required due to an LLVM bug, but I'm able to compile and run just fine if I manually link LDC generated files without the flag. Perhaps the bug in LLVM was fixed, and the restriction can be lifted, or a compiler flag to override the behavior can be added?

I've built LDC with LLVM at tag release_33, if that helps.

It is fixed in LLVM 3.4. With LLVM 3.3 it won't work if you specify -g.

Figured I'd close this as it's fixed when using LLVM 3.4. Please re-open if that's not a good reason.

Reopening this issue.
LDC needs -L"/LARGEADDRESSAWARE" for debug -g builds.
See LLVM bug: https://llvm.org/bugs/show_bug.cgi?id=15393

Finally obsolete due to CodeView debug infos and fixed by #1880.
