2016-01-05libiberty: {count,dup,write}argv: constify argv input slightlyMike Frysinger3-9/+15
Would be more useful if we could use "const char * const *", but there's a long standing bug where gcc warns about incompatible pointers when you try to pass in "char **". We can at least constify the array itself as gcc will not warn in that case.

2016-01-05libiberty: Tweak the documentation of libiberty's xcrc32 functionPatrick Palka2-7/+13
In some places the xcrc32 documentation refers to GDB's own crc32 implementation, but GDB no longer has its own crc32 implementation. It now uses libiberty's xcrc32 throughout. So this patch removes these references to GDB's now-nonexistent crc32 implementation. Also, there appears to be a bug in the table-generation program embedded within the documentation. When the variable "int i" is >= 128, the computation "i << 24" shifts a one bit into the sign bit (assuming a 32-bit int), which is UB. To avoid this UB, I think it is sufficient to make the induction variables i and j have type unsigned int. This bug seems latent, however. I ran the program before and after this change and the table output is the same.
2016-01-05libiberty: fix warnings about left shifting a negative value.Nick Clifton2-1/+7
GCC PR 66827 reports some problems with left shifting a negative value: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66827 Of the problems reported only two remain - in libiberty/regex.c: libiberty/regex.c:6970:11: runtime error: left shift of negative value -1 libiberty/regex.c:7165:4: runtime error: left shift of negative value -1 The patch below fixes these errors by casting the value to be shifted to unsigned before the shift occurs. No regressions were found in the libiberty testsuite or bootstrapping gcc (on an x86_64 target).
2015-11-28PR other/61321 - demangler crash on casts in template parametersPedro Alves4-8/+77
The fix for bug 59195: [C++ demangler handles conversion operator incorrectly] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59195 unfortunately makes the demangler crash due to infinite recursion, in case of casts in template parameters. For example, with: template<int> struct A {}; template <typename Y> void function_temp(A<sizeof ((Y)(999))>) {} template void function_temp<int>(A<sizeof (int)>); The 'function_temp<int>' instantiation above mangles to: _Z13function_tempIiEv1AIXszcvT_Li999EEE The demangler parses this as: typed name template name 'function_temp' template argument list builtin type int function type builtin type void argument list template (*) name 'A' template argument list unary operator operator sizeof unary operator cast template parameter 0 (**) literal builtin type int name '999' And after the fix for 59195, due to: static void d_print_cast (struct d_print_info *dpi, int options, const struct demangle_component *dc) { ... /* For a cast operator, we need the template parameters from the enclosing template in scope for processing the type. */ if (dpi->current_template != NULL) { dpt.next = dpi->templates; dpi->templates = &dpt; dpt.template_decl = dpi->current_template; } when printing the template argument list of A (what should be "<sizeof (int)>"), the template parameter 0 (that is, "T_", the '**' above) now refers to the first parameter of the the template argument list of the 'A' template (the '*' above), exactly what we were already trying to print. This leads to infinite recursion, and stack exaustion. The template parameter 0 should actually refer to the first parameter of the 'function_temp' template. Where it reads "for the cast operator" in the comment in d_print_cast (above), it's really talking about a conversion operator, like: struct A { template <typename U> explicit operator U(); }; We don't want to inject the template parameters from the enclosing template in scope when processing a cast _expression_, only when handling a conversion operator. The problem is that DEMANGLE_COMPONENT_CAST is currently ambiguous, and means _both_ 'conversion operator' and 'cast expression'. Fix this by adding a new DEMANGLE_COMPONENT_CONVERSION component type, which does what DEMANGLE_COMPONENT_CAST does today, and making DEMANGLE_COMPONENT_CAST just simply print its component subtree. I think we could instead reuse DEMANGLE_COMPONENT_CAST and in d_print_comp_inner still do: @@ -5001,9 +5013,9 @@ d_print_comp_inner (struct d_print_info *dpi, int options, d_print_comp (dpi, options, dc->u.s_extended_operator.name); return; case DEMANGLE_COMPONENT_CAST: d_append_string (dpi, "operator "); - d_print_cast (dpi, options, dc); + d_print_conversion (dpi, options, dc); return; leaving the unary cast case below calling d_print_cast, but seems to me that spliting the component types makes it easier to reason about the code. g++'s testsuite actually generates three symbols that crash the demangler in the same way. I've added those as tests in the demangler testsuite as well. And then this fixes PR other/61233 too, which happens to be a demangler crash originally reported to GDB, at: https://sourceware.org/bugzilla/show_bug.cgi?id=16957 Bootstrapped and regtested on x86_64 Fedora 20. Also ran this through GDB's testsuite. GDB will require a small update to use DEMANGLE_COMPONENT_CONVERSION in one place it's using DEMANGLE_COMPONENT_CAST in its sources. libiberty/ 2015-11-27 Pedro Alves <palves@redhat.com> PR other/61321 PR other/61233 * demangle.h (enum demangle_component_type) <DEMANGLE_COMPONENT_CONVERSION>: New value. * cp-demangle.c (d_demangle_callback, d_make_comp): Handle DEMANGLE_COMPONENT_CONVERSION.

2015-11-06Do not use libiberty's getpagesize on AndroidJoel Brobecker3-0/+18
Building libiberty on Android currently fails with the error message shown below. This was discovered by trying to build GDBserver for Android, which stopped building after libiberty became a GDBserver dependency. Here is the error message: [...]/getpagesize.c:64:1: error: redefinition of 'getpagesize' In file included from /[...]/getpagesize.c:34:0: /[...]/usr/include/unistd.h:171:23: note: previous definition of 'getpagesize' was here And looking at the definition, one can see that it defined as a static inline function... static __inline__ int getpagesize(void) { extern unsigned int __page_size; return __page_size; } ... which explains why the AC_CHECK_FUNCS test failed to detect the function, since there is no associated symbol to be linked in.

2014-06-11Delete temporary string within demangler even in failure cases.gdb-7.8-branchpointAndrew Burgess2-1/+9
A call to demangle_template might allocate storage within a temporary string even if the call to demangle_template eventually returns failure. This will never cause the demangler to crash, but does leak memory, as a result I've not added any tests for this. Calling string_delete is safe, even if nothing is allocated into the string, the string is initialised with string_init, so we know the internal pointers are NULL. libiberty/ChangeLog * cplus-dem.c (do_type): Call string_delete even if the call to demangle_template fails.
