mono 1.2.6 fails to build (darwin_stop_world.c)

[opendarwin.nospam@…]

There is already a ticket regarding mono, but it seems to be another problem.

I can reproduce this problem with OS X Leopard. My solution was to open the file

{{{ /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_mono/work/mono-1.2.6/libgc/darwin_stop_world.c }}}

by hand and jump to line 106. I removed the whole block enclosed by

  #if defined(_STRUCT_X86_EXCEPTION_STATE32) 
        lo = state.__esp;

        GC_push_one(state.__eax); 
        GC_push_one(state.__ebx); 
        GC_push_one(state.__ecx); 
        GC_push_one(state.__edx); 
        GC_push_one(state.__edi); 
        GC_push_one(state.__esi); 
        GC_push_one(state.__ebp); 
  #elif

It seems to work with the following code:

        lo = state.esp;

        GC_push_one(state.eax); 
        GC_push_one(state.ebx); 
        GC_push_one(state.ecx); 
        GC_push_one(state.edx); 
        GC_push_one(state.edi); 
        GC_push_one(state.esi); 
        GC_push_one(state.ebp); 

Of course then you'll just run into the next problem:

Then I opened mono/mini/mini-x86.h and deleted the block

#elif defined(__APPLE__) && defined(_STRUCT_MCONTEXT)
        #define UCONTEXT_REG_EAX(ctx) ((ctx)->uc_mcontext->__ss.__eax)
        #define UCONTEXT_REG_EBX(ctx) ((ctx)->uc_mcontext->__ss.__ebx)
        #define UCONTEXT_REG_ECX(ctx) ((ctx)->uc_mcontext->__ss.__ecx)
        #define UCONTEXT_REG_EDX(ctx) ((ctx)->uc_mcontext->__ss.__edx)
        #define UCONTEXT_REG_EBP(ctx) ((ctx)->uc_mcontext->__ss.__ebp)
        #define UCONTEXT_REG_ESP(ctx) ((ctx)->uc_mcontext->__ss.__esp)
        #define UCONTEXT_REG_ESI(ctx) ((ctx)->uc_mcontext->__ss.__esi)
        #define UCONTEXT_REG_EDI(ctx) ((ctx)->uc_mcontext->__ss.__edi)
        #define UCONTEXT_REG_EIP(ctx) ((ctx)->uc_mcontext->__ss.__eip)

and replaced

#elif defined(__APPLE__) && !defined(_STRUCT_MCONTEXT)

by

#elif defined(__APPLE__)

To summarize, it seems that the switches _STRUCT_X86_EXCEPTION_STATE32 and _STRUCT_MCONTEXT don't have the right values for OS X Leopard.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

Attached is a proposal to repair darwin_stop_world.c file.
I can only test the patch on Leopard so I hope it does not introduce any further problems.

[jmroot (Joshua Root)]

Assigning to maintainer.

[mww@…]

Thanks a lot for the patches everyone! I've submitted them alongside the update to v1.9; the patches to libgc and mini-x86/ppc.h are 10.5-only, so they won't do any harm on 10.4.
