x86 realmode: Use x86emu register file + defines
By using the (global) register file as defined by x86emu, we can use the same register access for YABEL and realmode interrupt handlers. - the x86 realmode interrupt handlers changed in signature - to access registers, use X86_$REGNAME now (eg. X86_EAX) - x86_exception_handler still uses struct eregs *regs to avoid spilling the x86emu register file stuff everywhere Coccinelle script that handled most of this commit: @ inthandler @ identifier FUNC, regs; @@ int FUNC( -struct eregs *regs +void ) { ... } @ depends on inthandler @ identifier regs; @@ -regs->eax +X86_EAX @ depends on inthandler @ identifier regs; @@ -regs->ebx +X86_EBX @ depends on inthandler @ identifier regs; @@ -regs->ecx +X86_ECX @ depends on inthandler @ identifier regs; @@ -regs->edx +X86_EDX @ depends on inthandler @ identifier regs; @@ -regs->esi +X86_ESI @ depends on inthandler @ identifier regs; @@ -regs->edi +X86_EDI @ depends on inthandler @ identifier regs; @@ -regs->eflags +X86_EFLAGS @ depends on inthandler @ identifier regs; @@ -regs->vector +M.x86.intno Change-Id: I60cc2c36646fe4b7f97457b1e297e3df086daa36 Signed-off-by: Patrick Georgi <patrick.georgi@secunet.com> Reviewed-on: http://review.coreboot.org/1891 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
