+
+ 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.

+
+ 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.

+ 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.
