-*** Build problems
-
-build/1411: build fails on hpux 10.20 and hpux 11.00 with CMA threads
-
-GDB does not build on HP/UX 10.20 or HP/UX 11.00 if the CMA
-thread package is installed. The compile error is:
-
- ../../gdb/hpux-thread.c:222: variable-size type declared outside of any function
-
-This happens only if the CMA thread package is installed.
-
-As a workaround, you can disable support for CMA threads
-by editing the file gdb/configure. Find the line:
-
- if test -f /usr/include/dce/cma_config.h ; then
-
-And replace it with:
-
- if false ; then
-
-*** Misc
-
-gdb/1560: Control-C does not always interrupt GDB.
-
-When GDB is busy processing a command which takes a long time to
-complete, hitting Control-C does not have the expected effect.
-The command execution is not aborted, and the "QUIT" message confirming
-the abortion is displayed only after the command has been completed.
-
-*** C++ support
-
-gdb/931: GDB could be more generous when reading types C++ templates on input
-
-When the user types a template, GDB frequently requires the type to be
-typed in a certain way (e.g. "const char*" as opposed to "const char *"
-or "char const *" or "char const*").
-
-gdb/1512: no canonical way to output names of C++ types
-
-We currently don't have any canonical way to output names of C++ types.
-E.g. "const char *" versus "char const *"; more subtleties arise when
-dealing with templates.
-
-gdb/1516: [regression] local classes, gcc 2.95.3, dwarf-2
-
-With gcc 2.95.3 and the dwarf-2 debugging format, classes which are
-defined locally to a function include the demangled name of the function
-as part of their name. For example, if a function "foobar" contains a
-local class definition "Local", gdb will say that the name of the class
-type is "foobar__Fi.0:Local".
-
-This applies only to classes where the class type is defined inside a
-function, not to variables defined with types that are defined somewhere
-outside any function (which most types are).
-
-gdb/1588: names of c++ nested types in casts must be enclosed in quotes
-
-You must type
- (gdb) print ('Foo::Bar') x
-or
- (gdb) print ('Foo::Bar' *) y
-instead of
- (gdb) print (Foo::Bar) x
-or
- (gdb) print (Foo::Bar *) y
-respectively.
-
-gdb/1091: Constructor breakpoints ignored
-gdb/1193: g++ 3.3 creates multiple constructors: gdb 5.3 can't set breakpoints
-
-When gcc 3.x compiles a C++ constructor or C++ destructor, it generates
-2 or 3 different versions of the object code. These versions have
-unique mangled names (they have to, in order for linking to work), but
-they have identical source code names, which leads to a great deal of
-confusion. Specifically, if you set a breakpoint in a constructor or a
-destructor, gdb will put a breakpoint in one of the versions, but your
-program may execute the other version. This makes it impossible to set
-breakpoints reliably in constructors or destructors.
-
-gcc 3.x generates these multiple object code functions in order to
-implement virtual base classes. gcc 2.x generated just one object code
-function with a hidden parameter, but gcc 3.x conforms to a multi-vendor
-ABI for C++ which requires multiple object code functions.
-
-*** Threads
-
-threads/1650: manythreads.exp
-
-On GNU/Linux systems that use the old LinuxThreads thread library, a
-program rapidly creating and deleting threads can confuse GDB leading
-to an internal error.
-
-This problem does not occur on newer systems that use the NPTL
-library, and did not occur with GDB 6.1.
-
-threads/2137: Native Solaris Thread Debugging broken.
-
-Use GDB 6.4 if thread debugging is needed on Solaris.
+None worth mentioning here.
