From 2b4c4cc415203ba612b819e52c1a3d1169ce7c99 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Mon, 25 Oct 2004 15:25:20 +0000 Subject: [PATCH] * stabs.c (stab_demangle_v3_arglist): New static function, broken out of stab_demangle_v3_argtypes. (stab_demangle_v3_argtypes): Call it. (stab_demangle_v3_arg): Handle DEMANGLE_COMPONENT_FUNCTION_TYPE. If we find an unrecognized component, print out its number. --- binutils/ChangeLog | 8 +++++++ binutils/stabs.c | 67 ++++++++++++++++++++++++++++++++++++++++++++++-------- 2 files changed, 66 insertions(+), 9 deletions(-) diff --git a/binutils/ChangeLog b/binutils/ChangeLog index 936792c..3d833e4 100644 --- a/binutils/ChangeLog +++ b/binutils/ChangeLog @@ -1,3 +1,11 @@ +2004-10-25 Ian Lance Taylor + + * stabs.c (stab_demangle_v3_arglist): New static function, broken + out of stab_demangle_v3_argtypes. + (stab_demangle_v3_argtypes): Call it. + (stab_demangle_v3_arg): Handle DEMANGLE_COMPONENT_FUNCTION_TYPE. + If we find an unrecognized component, print out its number. + 2004-10-25 David Mosberger * readelf.c (slurp_ia64_unwind_table): Support relocations against diff --git a/binutils/stabs.c b/binutils/stabs.c index 7af10ef..52a20e8 100644 --- a/binutils/stabs.c +++ b/binutils/stabs.c @@ -203,6 +203,8 @@ static debug_type *stab_demangle_argtypes (void *, struct stab_handle *, const char *, bfd_boolean *, unsigned int); static debug_type *stab_demangle_v3_argtypes (void *, struct stab_handle *, const char *, bfd_boolean *); +static debug_type *stab_demangle_v3_arglist + (void *, struct stab_handle *, struct demangle_component *, bfd_boolean *); static debug_type stab_demangle_v3_arg (void *, struct stab_handle *, struct demangle_component *, debug_type, bfd_boolean *); @@ -5073,7 +5075,6 @@ stab_demangle_v3_argtypes (void *dhandle, struct stab_handle *info, { struct demangle_component *dc; void *mem; - unsigned int alloc, count; debug_type *pargs; dc = cplus_demangle_v3_components (physname, DMGL_PARAMS | DMGL_ANSI, &mem); @@ -5093,13 +5094,35 @@ stab_demangle_v3_argtypes (void *dhandle, struct stab_handle *info, return NULL; } + pargs = stab_demangle_v3_arglist (dhandle, info, + dc->u.s_binary.right->u.s_binary.right, + pvarargs); + + free (mem); + + return pargs; +} + +/* Demangle an argument list in a struct demangle_component tree. + Returns a DEBUG_TYPE_NULL terminated array of argument types, and + sets *PVARARGS to indicate whether this is a varargs function. */ + +static debug_type * +stab_demangle_v3_arglist (void *dhandle, struct stab_handle *info, + struct demangle_component *arglist, + bfd_boolean *pvarargs) +{ + struct demangle_component *dc; + unsigned int alloc, count; + debug_type *pargs; + alloc = 10; pargs = (debug_type *) xmalloc (alloc * sizeof *pargs); *pvarargs = FALSE; count = 0; - for (dc = dc->u.s_binary.right->u.s_binary.right; + for (dc = arglist; dc != NULL; dc = dc->u.s_binary.right) { @@ -5108,8 +5131,8 @@ stab_demangle_v3_argtypes (void *dhandle, struct stab_handle *info, if (dc->type != DEMANGLE_COMPONENT_ARGLIST) { - fprintf (stderr, _("Unexpected type in demangle tree\n")); - free (mem); + fprintf (stderr, _("Unexpected type in v3 arglist demangling\n")); + free (pargs); return NULL; } @@ -5122,7 +5145,7 @@ stab_demangle_v3_argtypes (void *dhandle, struct stab_handle *info, *pvarargs = TRUE; continue; } - free (mem); + free (pargs); return NULL; } @@ -5138,8 +5161,6 @@ stab_demangle_v3_argtypes (void *dhandle, struct stab_handle *info, pargs[count] = DEBUG_TYPE_NULL; - free (mem); - return pargs; } @@ -5173,12 +5194,12 @@ stab_demangle_v3_arg (void *dhandle, struct stab_handle *info, case DEMANGLE_COMPONENT_COMPLEX: case DEMANGLE_COMPONENT_IMAGINARY: case DEMANGLE_COMPONENT_VENDOR_TYPE: - case DEMANGLE_COMPONENT_FUNCTION_TYPE: case DEMANGLE_COMPONENT_ARRAY_TYPE: case DEMANGLE_COMPONENT_PTRMEM_TYPE: case DEMANGLE_COMPONENT_ARGLIST: default: - fprintf (stderr, _("Unrecognized demangle component\n")); + fprintf (stderr, _("Unrecognized demangle component %d\n"), + (int) dc->type); return NULL; case DEMANGLE_COMPONENT_NAME: @@ -5269,6 +5290,34 @@ stab_demangle_v3_arg (void *dhandle, struct stab_handle *info, return debug_make_reference_type (dhandle, dt); } + case DEMANGLE_COMPONENT_FUNCTION_TYPE: + { + debug_type *pargs; + bfd_boolean varargs; + + if (dc->u.s_binary.left == NULL) + { + /* In this case the return type is actually unknown. + However, I'm not sure this will ever arise in practice; + normally an unknown return type would only appear at + the top level, which is handled above. */ + dt = debug_make_void_type (dhandle); + } + else + dt = stab_demangle_v3_arg (dhandle, info, dc->u.s_binary.left, NULL, + NULL); + if (dt == NULL) + return NULL; + + pargs = stab_demangle_v3_arglist (dhandle, info, + dc->u.s_binary.right, + &varargs); + if (pargs == NULL) + return NULL; + + return debug_make_function_type (dhandle, dt, pargs, varargs); + } + case DEMANGLE_COMPONENT_BUILTIN_TYPE: { char *p; -- 2.7.4
