Hello everyone.
Here is Thanksgiving day. Everyone went to hometown. But still i'm
porting gcc. :(
anyway, while i'm compiling libgcc, i got a error message.
>>-----------
../../../../sdk/gcc-4.3.3/libgcc/../gcc/unwind-dw2.c: In function
‘uw_install_context_1’:
../../../../sdk/gcc-4.3.3/libgcc/../gcc/unwind-dw2.c:1532: error:
unrecognizable insn:

../../../../sdk/gcc-4.3.3/libgcc/../gcc/unwind-dw2.c:1503 (set (reg:SI

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
--------------<<
the statement is memcpy in unwind-dw2.c:1503
>>------------ unwind-dw2.c:1500-1505
if (dwarf_reg_size_table[i] == sizeof (_Unwind_Word))
{
w = (_Unwind_Internal_Ptr) t;
memcpy (c, &w, sizeof (_Unwind_Word));
}
else
-----------------<<
memcpy is just a function call. so i can not understand why the
compiler try to set some value into register.
Also, i've known that (scratch:m ) is used with clobber RTL. But
scratch is used without (clobber ) in the error message.
Do i specify this RTL into machine description file? or... did i write
something wrong ?
