2005-04-25 Jan Beulich <jbeulich@novell.com> * macro.c (macro_expand_body): Replace locals indicator parameters with actual macro_entry. New local variables macro_line and err. Don't return when encountering an error, just record the fact. Detect local symbol name colliding with parameter. Track line number inside of macro expansion. (do_formals): Move local variable name to wider scope. Check parameter of the same name doesn't already exist. In MRI mode, also check it doesn't collide with the argument count pseudo-parameter). (define_macro): Add file and line number parameters. Remove local variable namestr. New local variable error. Initialize macro_entry members file, line, and name. Don't return when encountering an error, just record the fact. Use %s in some diagnostics for read.c to insert the macro name. Free macro_entry on error. (macro_expand): Pass macro_entry to macro_epand_body. Don't return when encountering an error, just record the fact. (expand_irp): Don't return when encountering an error, just record the fact. * macro.h (macro_struct): New members name, file, and line. (define_macro): Add file and line number parameters. * read.c (s_macro): Pass file and line to define_macro. Tag warning regarding pseudo-op redefinition with the file/line that macro definition started at. gas/testsuite/ 2005-04-25 Jan Beulich <jbeulich@novell.com> * gas/macros/badarg.s: Add tests for collisions between/among macro parameters and local symbols. * gas/macros/badarg.l: Adjust.

into the list to speed up formal search. Each formal knows its
