hi Ian, thank you for reply.
I didn't find something in a.h has #define used by my .md file.
but I find error at insn-recog.c.
When I delete all "#line xxx" in insn-recog.c, compile it as:
gcc -c -g -O0 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall
-Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes

insn-recog.c -o insn-recog.o
I get a lot of errors like this:

The wrong code is :
L9284: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, {);
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (13)])
goto L9285;
goto ret0;
L9285: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, |);
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (45)])
goto L9286;
goto ret0;
L9286: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, });
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (14)])
goto L9287;
goto ret0;
L9287: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, ~);
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (46)])
goto L9288;
goto ret0;
L9288: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, );
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (15)])
goto L9289;
goto ret0;
L9289: ATTRIBUTE_UNUSED_LABEL
x3 = XEXP (x2, );
if (x3 == const_int_rtx[MAX_SAVED_CONST_INT + (47)]
&&
(TARGET_HR_VECTORS))
{
return 1072; /* hr_vpunpcklbh */
}
goto ret0;
It's so weird!
