That's not right. GCC does not use GC memory everywhere, passes can also heap-allocate and/or use obstacks. You do have to be careful when mixing heap-allocated with GC memory, but for pass-local memory allocation schemes, heap and obstacks are perfectly fine. Paulo, you may also want to use the XNEW/XCNEW wrapper macros. They are handy shorthand wrappers around malloc. Another convenient way of allocating a pool of memory is to use obstacks (See libiberty/obstack.c).
