Just to make sure I understood the calling convention used by DMD on x86:

core.thread.callWithStackShell currently uses pushad to ensure that all registers are on the stack to be scannable by the GC. But in theory it would be enough to push EBX, ESI and EDI, as the other registers would be saved by the callWithStackShell caller anyway if they contained something of interest. Correct?

Thanks,
David
