Hi,
I am nearly through :) The remaining macros left to be ported are
REGPARM_MAX and SSE_REGPARM_MAX. The sysv_abi uses 6 regs and 8 sses,
ms_abi uses 4 regs and 4 sse registers. The problem is for example the use
in i386.md of SSE_REGPARM_MAX without any hint, how to choose the required
abi. Do you have an idea how this could be done ?
Cheers,
i.A. Kai Tietz
