From 02ddf1568180e41117d6d2804636e64775ac37b6 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 25 Apr 2005 06:43:46 +0000 Subject: gas/ 2005-04-25 Jan Beulich * 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 * gas/macros/badarg.s: Add tests for collisions between/among macro parameters and local symbols. * gas/macros/badarg.l: Adjust. --- gas/macro.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'gas/macro.h') diff --git a/gas/macro.h b/gas/macro.h index 54c7f0c..958a84bd 100644 --- a/gas/macro.h +++ b/gas/macro.h @@ -60,6 +60,9 @@ typedef struct macro_struct int formal_count; /* Number of formal args. */ formal_entry *formals; /* Pointer to list of formal_structs. */ struct hash_control *formal_hash; /* Hash table of formals. */ + const char *name; /* Macro name. */ + char *file; /* File the macro was defined in. */ + unsigned int line; /* Line number of definition. */ } macro_entry; /* Whether any macros have been defined. */ @@ -76,7 +79,7 @@ extern void macro_init extern void macro_set_alternate (int); extern void macro_mri_mode (int); extern const char *define_macro - (int, sb *, sb *, int (*) (sb *), const char **); + (int, sb *, sb *, int (*) (sb *), char *, unsigned int, const char **); extern int check_macro (const char *, sb *, const char **, macro_entry **); extern void delete_macro (const char *); extern const char *expand_irp (int, int, sb *, sb *, int (*) (sb *)); -- cgit v1.1
