Bug 22573 – DMD compiler errors on Illumos/Solaris

Hello, I have been trying to compile DMD on OpenIndiana, an Illumos/Solaris system. My approach was like this: 1. compile GDC 2. use GDC to build DMD 3. use DMD to build druntime The procedure was repeated with the old and the new (will be available in GCC 12) D implementations of gcc. In both cases the compilation of druntime aborted with the following error message: --- ERROR: This is a compiler bug. Please report it via https://issues.dlang.org/enter_bug.cgi with, preferably, a reduced, reproducible example and the information below. DustMite (https://github.com/CyberShadow/DustMite/wiki) can help with the reduction. --- DMD v2.098.0-317-g9d1027cfb-dirty predefs DigitalMars LittleEndian D_Version2 all D_SIMD Posix ELFv1 Solaris CppRuntime_Gcc D_InlineAsm_X86_64 X86_64 D_LP64 D_PIC D_ModuleInfo D_Exceptions D_TypeInfo D_HardFloat binary ../dmd/generated/solaris/release/64/dmd version v2.098.0-317-g9d1027cfb-dirty config DFLAGS (none) --- core.exception.AssertError@src/dmd/backend/obj.d-mixin-196(203): Assertion failure ---------------- ../../../../libphobos/libdruntime/core/exception.d:582 onAssertError [0x7eb6b4] src/dmd/backend/obj.d-mixin-196:203 _ZN3Obj4initEP9OutBufferPKcS3_ [0x697b5b] src/dmd/glue.d:341 _Z9obj_startPKc [0x696127] src/dmd/glue.d:135 void dmd.glue.generateCodeAndWrite(dmd.dmodule.Module[], const(char)*[], const(char)[], const(char)[], bool, bool, bool, bool, bool) [0x43fa8c] src/dmd/mars.d:597 int dmd.mars.tryMain(ulong, const(char)**, ref dmd.globals.Param) [0x442055] src/dmd/mars.d:1020 _Dmain [0x44dc6d] gmake: *** [posix.mak:377: generated/solaris/release/64/libdruntime.a] Fehler 1 I do not know how to fix this, but maybe someone here could help me out?

The dmd backend has only ever been ported to Solaris i[3456]86, IIRC. So it's likely that config is not being set-up correctly for x86_64.

Nope, it's a typo. https://github.com/dlang/dmd/blob/master/src/dmd/backend/backconfig.d#L245 Raisea pull to fix that, my guess is that should be `(EX_SOLARIS | EX_SOLARIS64)`.

This fixes the above issue.
