- I'am not happy with the new fields localvarsize and localconstoffset
in rautils.toprrec. Increasing the size of toprrec will probably
increase memory usage of the compiler, I also didn't get yet the use of
the fields: localsym and localsymofs should allow to figure out the same?
I need this to validate memory-reference-operands (only SSE- or AVX
opcodes).
Calculate the size of record-elements is impossible (with localsym) in
Tx86Instruction.AddReferenceSize.
Get the offset of record-elements is impossible (with localsymofs) in
Tx86Instruction.AddReferenceSize.
type
TYMMWord = record
i0: dword;
i1: dword;
i2: dword;
i3: dword;
i4: dword;
i5: dword;
i6: dword;
i7: dword;
end;
datatyp localvarsize tabstractnormalvarsym(localsym)
localconstoffset localsymofs
byte 1 1
word 2 2
dword 4 4
...
TYMMWord 32 32
0
0
TYMMWord.i1 4 32
0
4
TYMMWord.i1 + 16 4 32
16 20
I have not simple idea how to use localsym and localsymofs to validate
memory-reference-size.
Besides this, the changes look already very good to me!
Thanks
