- The Fortran front end can not be built with most vendor compilers;
- it must be built with GCC. As a result, you may get an error if you
- do not follow the install instructions carefully.
-
- In particular, instead of using "make" to build GCC, you should use
- "make bootstrap" if you are building a native compiler or "make cross"
- if you are building a cross compiler.

+
+ Relase Notes
+
+ See [1]this message for a list of bugs fixed in this released.
+
+ Caveats
+
+ * This GCC release is based on the GCC 3.1 sourcebase, and thus has
+ all the [2]changes in the GCC 3.1 series. In addition, GCC 3.2 has
+ a number of C++ ABI fixes which make its C++ compiler generate
+ binary code which is incompatible with the C++ compilers found in
+ earlier GCC releases, including GCC 3.1 and GCC 3.1.1.
+
+ New Languages and Language specific improvements
+
+ C++
+
+ * There are now no known differences between the C++ ABI implemented
+ in GCC and the multi-vendor standard. We believe that the ABI for
+ the C++ standard library is now stable and will not change in
+ future versions of the compiler. However, hard experience has
+ taught us to be cautious; it is possible that more problems will
+ be found. It is our intention to make changes to the ABI only if
+ they are necessary for correct compilation of C++, as opposed to
+ conformance to the ABI documents.
+ * For details on how to build an ABI compliant compiler for
+ GNU/Linux systems, check the [3]common C++ ABI page.
+
+ New Targets and Target Specific Improvements
+
+ x86-64
+
+ * A bug whereby the complier could generated bad code for bzero has
+ been fixed.

General Optimizer Improvements
* Jan Hubicka, SuSE Labs, together with Richard Henderson, Red Hat,
! and Andreas Jaeger, SuSE Labs, has contributed [1]infrastructure
for profile driven optimizations.
Options -fprofile-arcs and -fbranch-probabilities can now be used
to improve speed of the generated code by profiling the actual
program behaviour on typical runs. In the absence of profile info
the compiler attempts to guess the profile statically.
! * [2]SPEC2000 and [3]SPEC95 benchmark suites are now used daily to
monitor performance of the generated code.
According to the SPECInt2000 results on an AMD Athlon CPU, the
code generated by GCC 3.1 is 6% faster on the average (8.2% faster
with profile feedback) compared to GCC 3.0. The code produced by
GCC 3.0 is about 2.1% faster compared to 2.95.3. Tests were done
using the -O2 -march=athlon command-line options.
! * Alexandre Oliva, of [4]Red Hat, has generalized the tree inlining
! infrastructure developed by [5]CodeSourcery, LLC for the C++ front
end, so that it is now used in the C front end too. Inlining
functions as trees exposes them earlier to the compiler, giving it
more opportunities for optimization.

GCC 3.0 Caveats
+ * -fstrict-aliasing is now part of -O2 and higher optimization
+ levels. This allows the compiler to assume the strictest aliasing
+ rules applicable to the language being compiled. For C and C++,
+ this activates optimizations based on the type of expressions.
+ This optimization may thus break old, non-compliant code.
* Enumerations are now properly promoted to int in function
parameters and function returns. Normally this change is not
visible, but when using -fshort-enums this is an ABI change.
