I can request the feature be added to the AIX Assembler, but it is not going to be available on any timeframe necessary for the GCC 3.0 release. A feature supporting this extension also is not available in the GNU Assembler. It might be easier to get something into GNU as, but it is not compatible with older versions of GNU as (can you say autoconf test for a particular feature?). And the assembly output will not be compatible with the AIX Assembler. This does not seem like an important enough problem to break compatibility with the AIX assembler and/or require the GNU Assembler for any source code compiled with debugging enabled. The GNU Compiler cannot simply require an unimplemented feature in the assembler without previously having the feature in the product plan for the assembler. David
