Hello,
I'm slowly starting to wrap my head around the way the ISA language works,
but I can't seem to figure out what certain parameters are to a format. For
example in the alpha ISA's decode blocks I see this:
888 0x1f: decode PALMODE {
889 0: OpcdecFault::hw_st_cond();
890 format HwStore {
891 1: decode HW_LDST_COND {
892 0: decode HW_LDST_QUAD {
893 0: hw_st({{ EA = (Rb + disp) & ~3; }},
894 {{ Mem.ul = Ra<31:0>; }}, L, IsSerializing,
IsSerializeBefore);
I understand the basic structure here: first two arguments are code
literals, the last two are flags from static_inst.hh, but I can't figure
out what "L" is. When I grep for L, I can't find anything (i.e. it's not a
bitfield, not a flag). Looking at the corresponding python code it seems
like maybe it's just a string literal? Is this right?
Thanks in advance,
Paul
