-mips*-*-*
-powerpc*-*-*
-sparc*-*-*
-GDB's SPARC, MIPS and PowerPC targets, in 6.0, have not been updated
-to use the new frame mechanism.
+*** Build problems
-People encountering problems with these targets should consult GDB's
-web pages and mailing lists (http://www.gnu.org/software/gdb/) to see
-if there is an update.
+build/1411: build fails on hpux 10.20 and hpux 11.00 with CMA threads
-arm-*-*
+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's ARM target, in 6.0, has not been updated to use the new frame
-mechanism.
+ ../../gdb/hpux-thread.c:222: variable-size type declared outside of any function
-Fortunately the ARM target, in the GDB's mainline sources, has been
-updated so people encountering problems should consider downloading a
-more current GDB (http://www.gnu.org/software/gdb/current).
+This happens only if the CMA thread package is installed.
-*** Regressions since gdb 6.0
+As a workaround, you can disable support for CMA threads
+by editing the file gdb/configure. Find the line:
-gdb/826: variables in C++ namespaces have to be enclosed in quotes
+ if test -f /usr/include/dce/cma_config.h ; then
-When referring to a variable in C++ code that is inside a
-namespace, you have to put it inside single quotes.
+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
typed in a certain way (e.g. "const char*" as opposed to "const char *"
or "char const *" or "char const*").
-gdb/1505: [regression] gdb prints a bad backtrace for a thread
-
-When backtracing a thread, gdb doesn't stop until it hits garbage.
-This is sensitive to the operating system and thread library.
-
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.
function, not to variables defined with types that are defined somewhere
outside any function (which most types are).
-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.
+gdb/1588: names of c++ nested types in casts must be enclosed in quotes
-*** Regressions since gdb 5.3
+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
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.
