Hi, yes, I think this is necessary on VMS. Could you submit formally a patch (I can't approve it, but it is a required first step). > That gets further, then hits > > > src/gcc-4.5.0/libiberty/regex.c: In function 'byte_insert_op2': > /src/gcc-4.5.0/libiberty/regex.c:4279:1: error: unrecognizable insn: > (insn 62 61 63 5 /src/gcc-4.5.0/libiberty/regex.c:4276 (set (reg:DI 135) > (plus:SI (subreg/s:SI (reg/v/f:DI 109 [ pfrom ]) 0) > (const_int 5 [0x5]))) -1 (nil)) > /src/gcc-4.5.0/libiberty/regex.c:4279:1: internal compiler error: in > extract_insn, at recog.c:2103 > Please submit a full bug report, > with preprocessed source if appropriate. > See <http://gcc.gnu.org/bugs.html> for instructions. > make: *** [regex.o] Error 1 I suppose you have hit a 32/64 pointer issue. This requires some investigation! We plan to fix them, but we haven't yet started this work on gcc 4.5 Tristan.
