http://d.puremagic.com/issues/show_bug.cgi?id=5264 Summary: x86_64 changes for druntime 2 Product: D Version: D2 Platform: Other OS/Version: All Status: NEW Severity: normal Priority: P2 Component: druntime AssignedTo: sean invisibleduck.org ReportedBy: braddr puremagic.com --- Created an attachment (id=830) most of the changes to get druntime 2 to build with dmd -m64 I spent a couple hours today working on getting druntime 2 to build with the x86_64 dmd compiler. It's not 100% so far, but almost there. What's broken: 1) lifetime.d has 4 va_arg calls commented out. The compiler croaks with: src/core/stdc/stdarg.d(229): Error: static assert "not a valid argument type for va_arg" src/rt/lifetime.d(814): instantiated from here: va_arg!(ulong) 2) lifetime.d _d_arrayappendcT needs to be altered to work with varargs properly. The 64 bit support is fragile/hacky/whatever and I haven't pieced together how this code evolved between d1 and d2's runtimes. 3) lifetime.d _d_arrayshrinkfit() crashes the backend of the compiler: function _d_arrayshrinkfit cod2.c:1769: assert(stackpush == stackpushsave) // 0xfffffffc == 0 Normally I'd create 3 bugs since there's 3 different issues, but I don't think that'd be useful here. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=5264 --- though I suspect they're all related. If the fix for this reduction doesn't solve all of them, I'll re-reduce the next one. ========= module hrm; struct BlkInfo { size_t size; } extern (C) BlkInfo gc_qalloc(size_t sz, uint ba); void __setArrayAllocLength(ref BlkInfo info) { if (info.size) {} } extern (C) void foo() { BlkInfo info = gc_qalloc(0, 0); __setArrayAllocLength(info); } ====== $ ../dmd-trunk/src/dmd -c -m64 hrm.d Internal error: backend/cod1.c 2554 Building in 32 bit mode (without -m64) works just fine. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=5264 Brad Roberts <braddr puremagic.com> changed: What |Removed |Added ---------------------------------------------------------------------------- obsolete| | --- Created an attachment (id=835) remaining changes to pass semantic checks of druntime (actually not all, see also bug 5263 for intrinsic cleanup) This time I ran the druntime and phobos unittests on 32 bit. They pass. The 64 bit tests can't be run yet as there's still dmd codgen bugs while building druntime. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
