GCC 3.0
TBA
The [1]GNU project and the GCC developers are pleased to announce the
release of GCC version 3.0.
GCC used to stand for the GNU C Compiler, but since the compiler
supports several other languages aside from C, it now stands for the
GNU Compiler Collection.
GCC 3.0 has several new optimizations, new targets, new languages and
many other new features. See the [2]new features page for a more
complete list.
The GCC developers would like to thank the numerous people that have
contributed new features, test results, bugfixes, etc to GCC. This
[3]amazing group of volunteers is what makes GCC successful.
And finally, we can't in good conscience fail to mention some
[4]caveats to using GCC 3.0.
For additional information about GCC please refer to the [5]GCC
project web site or contact the [6]GCC development mailing list.

GCC 3.0 New Features
* General Optimizer Improvements:
+ [1]Basic block reordering pass.
+ New if-conversion pass with support for conditional
(predicated) execution.
+ New tail call and sibling call elimination optimizations.
+ New register renaming pass.
+ New (experimental) [2]static single assignment (SSA)
representation support.
+ New dead-code elimination pass implemented using the SSA
representation.
+ [3]Global null pointer test elimination.
+ [4]Global code hoisting/unification.
+ More builtins and optimizations for stdio.h, string.h and old
BSD functions, as well as for ISO C99 functions.
+ New builtin __builtin_expect for giving hints to the branch
predictor.
* New Languages and Language specific improvements:
+ The GNU Compiler for the Java(TM) language (GCJ) is now
integrated and supported, including the run-time library
containing most common non-GUI Java classes, a bytecode
interpreter, and the Boehm conservative garbage collector.
Many bugs have been fixed. GCJ can compile Java source or
Java bytecodes to either native code or Java class files, and
supports native methods written in either the standard JNI or
the more efficient and convenient CNI.
+ New C++ ABI, capable of inter-operating with other IA-64
compilers.
+ The new ABI also significantly reduces the size of symbol and
debug information.
+ New C++ support library and many C++ bug fixes, vastly
improving our conformance to the ISO C++ standard.
+ New [5]inliner for C++.
+ Rewritten C preprocessor, integrated into the C, C++ and
Objective C compilers, with very many improvements including
ISO C99 support and [6]improvements to dependency generation.
+ Support for more [7]ISO C99 features.
+ Many improvements to support for checking calls to format
functions such as printf and scanf, including support for ISO
C99 format features, extensions from the Single Unix
Specification and GNU libc 2.2, checking of strfmon formats
and features to assist in auditing for format string security
bugs.
+ New warnings for C code that may have undefined semantics
because of violations of sequence point rules in the C
standard (such as a = a++;, a[n] = b[n++]; and a[i++] = i;),
included in -Wall.
+ Additional warning option -Wfloat-equal.
+ Improvements to -Wtraditional.
+ Fortran improvements are listed in [8]the Fortran
documentation.
* New Targets and Target Specific Improvements:
+ New x86 back-end, generating much improved code.
+ Support for a generic i386-elf target contributed.
+ New option to emit x86 assembly code using Intel style syntax
(-mintel-syntax).
+ HPUX 11 support contributed.
+ Improved PowerPC code generation, including scheduled
prologue and epilogue.
+ Port of gcc to Intel's IA-64 processor contributed.
+ Port of gcc to Motorola's MCore 210 and 340 contributed.
+ New unified back-end for Arm, Thumb and StrongArm
contributed.
+ Port of gcc to Intel's XScale processor contributed.
+ Port of gcc to Atmel's AVR microcontrollers contributed.
+ Port of gcc to Mitsubishi's D30V processor contributed.
+ Port of gcc to Matsushita's AM33 processor (a member of the
MN10300 processor family) contributed.
+ Port of gcc to Fujitsu's FR30 processor contributed.
+ Port of gcc to Motorola's 68HC11 and 68HC12 processors
contributed.
+ Port of gcc to Sun's picoJava processor core contributed.
* Documentation improvements:
+ Substantially rewritten and improved C preprocessor manual.
+ Many improvements to other documentation.
+ Manpages for gcc, cpp and gcov are now generated
automatically from the master Texinfo manual, eliminating the
problem of manpages being out of date. (The generated
manpages are only extracts from the full manual, which is
provided in Texinfo form, from which info, HTML, other
formats and a printed manual can be generated.)
+ Generated info files are included in the release tarballs
alongside their Texinfo sources, avoiding problems on some
platforms with building makeinfo as part of the GCC
distribution.
* Other significant improvements:
+ Garbage collection used internally by the compiler for most
memory allocation instead of obstacks.
+ Lengauer and Tarjan algorithm used for computing dominators
in the CFG. This algorithm can be significantly faster and
more space efficient than our older algorithm.
+ gccbug script provided to assist in submitting bug reports to
the GCC GNATS bug tracking database. (Bug reports previously
submitted directly to the GCC mailing lists, for which no
GNATS bug tracking number has been received, should be
submitted again to the bug tracking database using gccbug if
you can reproduce the problem with GCC 3.0.)
+ The internal libgcc library is [9]built as a shared library
on systems that support it.
+ Extensive testsuite included with GCC, with many new tests.
In addition to tests for GCC bugs that have been fixed, many
tests have been added for language features, compiler
warnings and builtin functions.
+ Additional language-independent warning options -Wpacked,
-Wpadded, -Wunreachable-code and -Wdisabled-optimization.
+ Target-independent options -falign-functions, -falign-loops
and -falign-jumps.
* Plus a great many bugfixes and almost all the [10]features found
in GCC 2.95.

http://gcc.gnu.org/gcc-3.0/caveats.html
GCC 3.0 Caveats
* 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.
* The undocumented extension that allowed C programs to have a label
at the end of a compound statement has been deprecated and may be
removed in a future version. Programs that now generate a warning
about this may be fixed by adding a null statement (a single
semicolon) after the label.
* The poorly documented extension that allowed string constants in
C, C++ and Objective C to contain unescaped newlines has been
deprecated and may be removed in a future version. Programs using
this extension may be fixed in several ways: the bare newline may
be replaced by \n, or preceded by \n\, or string concatenation may
be used with the bare newline preceded by \n" and " placed at the
start of the next line.
* The Chill compiler is not included in GCC 3.0, because of the lack
of a volunteer to convert it to use garbage collection.

GCC 2.95.3
March 16, 2001
The GNU project and the GCC developers are pleased to announce the
release of GCC version 2.95.3. GCC used to stand for the GNU C
Compiler, but since the compiler supports several other languages
aside from C, it now stands for the GNU Compiler Collection.
This is a minor release to address several bugs in the [1]GCC version
2.95.2 release.
* Generic bugfixes and improvements
+ Fix numerous problems that caused incorrect optimization in
the register reloading code.
+ Fix numerous problems that caused incorrect optimization in
the loop optimizer.
+ Fix aborts in the functions build_insn_chain and scan_loops
under some circumstances.
+ Fix an alias analysis bug.
+ Fix an infinite compilation bug in the combiner.
+ A few problems with complex number support have been fixed.
+ It is no longer possible for gcc to act as a fork bomb when
installed incorrectly.
+ The -fpack-struct option should be recognized now.
+ Fixed a bug that caused incorrect code to be generated due to
a lost stack adjustment.
* Platform specific bugfixes and improvements
+ Support building ARM toolchains hosted on Windows.
+ Fix attribute calculations in ARM toolchains.
+ arm-linux support has been improved.
+ Fix a PIC failure on sparc targets.
+ On ix86 targets, the regparm attribute should now work
reliably.
+ Several updates for the h8300 port.
The whole suite has been extensively [2]regression tested and
[3]package tested. It should be reliable and suitable for widespread
use.
The GCC 2.95 release has several new optimizations, new targets, new
languages and other new features as compared to EGCS 1.1 or GCC 2.8.
See the [4]new features page for a more complete list of new features
found in the GCC 2.95 releases.
The sources include installation instructions in both HTML and
plaintext forms in the install directory in the distribution. However,
the most up to date [5]installation instructions and [6]build/test
status are on the web pages. We will update those pages as new
information becomes available.
The GCC developers would like to thank the numerous people that have
contributed new features, test results, bugfixes, etc to GCC. This
[7]amazing group of volunteers is what makes GCC successful.
And finally, we can't in good conscience fail to mention some
[8]caveats to using GCC 2.95.3.
