b36c1ccb1f libiberty: {count,dup,write}argv: constify argv input slightly
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.

4bec0ef03e libiberty: Tweak the documentation of libiberty's xcrc32 function
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.

13b356b2b5 libiberty: fix warnings about left shifting a negative value.
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).

c4be264168 PR other/61321 - demangler crash on casts in template parameters
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.

82ef0f7074 Do not use libiberty's getpagesize on Android
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.

This patch prevents getpagesize.c to be compiled in by hard-coding
the fact that getpagesize is available on android hosts.

519b5f619b libiberty/mkstemps.c: Include <time.h> if <sys/time.h> not available.
Attempting to build libiberty on LynxOS-178 fails trying to compile
mkstemps.c with the following error:

    mkstemps.c:84:18: error: storage size of 'tv' isn't known
       struct timeval tv;
                      ^

This file would normally include <sys/time.h> to get the type's
definition, but unfortunately LynxOS-178 does not want us to use
<sys/time.h>, only <time.h>. The configure script correctly finds
this out and generates a config.h file where HAVE_SYS_TIME_H is
undefined:

/* Define to 1 if you have the <sys/time.h> header file. */
/* #undef HAVE_SYS_TIME_H */

This patch fixes the build issue by falling back on including <time.h>
if <sys/time.h> could not be included (and provided that HAVE_TIME_H

5af04e20f6 Use strtod instead of strtold in libiberty/d-demangle.c
strtold is currently used to decode templates which have a floating-point
value encoded inside; but this routine is not available on some systems,
such as Solaris 2.9 for instance.

This patch fixes the issue by replace the use of strtold by strtod.
It reduces a bit the precision, but it should still remain acceptable
in most cases.

libiberty/ChangeLog:

        * d-demangle.c: Replace strtold with strtod in global comment.
        (strtold): Remove declaration.
        (strtod): New declaration.

173373c6f6 Delete temporary string within demangler even in failure cases.
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.

Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined
crashes, with:

Note dc=0x1, which is obviously a bogus pointer.  This is the end of
d_dump recursing for a component type that that doesn't actually have
subtrees:

 787       d_dump (d_left (dc), indent + 2);
 788       d_dump (d_right (dc), indent + 2);

This fixes the two cases the testsuite currently trips on.

Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted.  So we end up initializing properly
at the top only to reset it at the end all the time.
