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. - _________________________________________________________________ - - - Please send FSF & GNU inquiries & questions to [11]gnu@gnu.org. - There are also [12]other ways to contact the FSF. - These pages are maintained by [13]The GCC team. - Please send comments on these web pages and GCC to - [14]gcc@gcc.gnu.org, send other questions to [15]gnu@gnu.org. - Copyright (C) Free Software Foundation, Inc., 59 Temple Place - - Suite 330, Boston, MA 02111, USA. - Verbatim copying and distribution of this entire article is - permitted in any medium, provided this notice is preserved. - Last modified 2001-05-30. - -References - - 1. http://gcc.gnu.org/news/reorder.html - 2. http://gcc.gnu.org/news/ssa.html - 3. http://gcc.gnu.org/news/null.html - 4. http://gcc.gnu.org/news/unify.html - 5. http://gcc.gnu.org/news/inlining.html - 6. http://gcc.gnu.org/news/dependencies.html - 7. http://gcc.gnu.org/gcc-3.0/c99status.html - 8. http://gcc.gnu.org/onlinedocs/g77_news.html - 9. http://gcc.gnu.org/gcc-3.0/libgcc.html - 10. http://gcc.gnu.org/gcc-2.95/features.html - 11. mailto:gnu@gnu.org - 12. http://www.gnu.org/home.html#ContactInfo - 13. http://gcc.gnu.org/about.html - 14. mailto:gcc@gcc.gnu.org - 15. mailto:gnu@gnu.org -====================================================================== -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. - _________________________________________________________________ - - - Please send FSF & GNU inquiries & questions to [1]gnu@gnu.org.

This - is particularly noticeable when compiling older versions of the - Linux kernel (2.0.xx). Please refer to the [1]FAQ for more - information on this issue. - * GCC 2.95 implements type based alias analysis to disambiguate - memory references. Some programs, particularly the Linux kernel - violate ANSI/ISO aliasing rules and therefore may not operate - correctly when compiled with GCC 2.95. Please refer to the [2]FAQ - for more information on this issue. - * GCC 2.95 has a known bug in its handling of complex variables for - 64bit targets. Instead of silently generating incorrect code, GCC - 2.95 will issue a fatal error for situations it can not handle. - This primarily affects the Fortran community as Fortran makes more - use of complex variables than C or C++. - * GCC 2.95 has an integrated libstdc++, but does not have an - integrated libg++. Furthermore old libg++ releases will not work - with GCC 2.95. You can retrieve a recent copy of libg++ from the - [3]GCC ftp server. - Note most C++ programs only need libstdc++. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, rs6000/powerpc and mips based - platforms. Exception handling is known to work on x86 GNU/Linux - platforms with shared libraries. - * In general, GCC 2.95 is more rigorous about rejecting invalid C++ - code or deprecated C++ constructs than G++ 2.7, G++ 2.8, EGCS 1.0, - or EGCS 1.1. As a result it may be necessary to fix C++ code - before it will compile with GCC 2.95. - * G++ is also converting toward the ISO C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of g++) may no longer be accepted. - The flag -fpermissive may allow some non-conforming code to - compile with GCC 2.95. - * GCC 2.95 compiled C++ code is not binary compatible with EGCS - 1.1.x, EGCS 1.0.x or GCC 2.8.x. - * GCC 2.95 does not have changes from the GCC 2.8 tree that were - made between Sept 30, 1998 and April 30, 1999 (the official end of - the GCC 2.8 project). Future GCC releases will include all the - changes from the defunct GCC 2.8 sources. - _________________________________________________________________ - - - Please send FSF & GNU inquiries & questions to [4]gnu@gnu.org.

By providing more accurate information - to the priority based allocator, we get better register - allocation. - * The register reloading phase of the compiler optimizes spill code - much better than in previous releases. - * Some bad interactions between the register allocator and - instruction scheduler have been fixed, resulting in much better - code for certain programs. Additionally, we have tuned the - scheduler in various ways to improve performance of generated code - for some architectures. - * The compiler's branch shortening algorithms have been - significantly improved to work better on targets which align jump - targets. - * The compiler now supports -Os to prefer optimizing for code space - over optimizing for code speed. - * The compiler will now totally eliminate library calls which - compute constant values. This primarily helps targets with no - integer div/mul support and targets without floating point - support. - * The compiler now supports an extensive "--help" option. - * cpplib has been greatly improved and may be suitable for limited - use. - * Memory footprint for the compiler has been significantly reduced - for some pathological cases. - * The time to build EGCS has been improved for certain targets - (particularly the alpha and mips platforms). - * Many infrastructure improvements throughout the compiler, plus the - usual mountain of bugfixes and minor improvements. - * Target dependent improvements: - + SPARC port now includes V8 plus and V9 support as well as - performance tuning for Ultra class machines. The SPARC port - now uses the Haifa scheduler. - + Alpha port has been tuned for the EV6 processor and has an - optimized expansion of memcpy/bzero. The Alpha port now uses - the Haifa scheduler. - + RS6000/PowerPC: EGCS 1.1 includes support for the Power64 - architecture and aix4.3 support. The RS6000/PowerPC port now - uses the Haifa scheduler. - + x86: Alignment of static store data and jump targets is per - Intel recommendations now. Various improvements throughout - the x86 port to improve performance on Pentium processors. - Conditional move support has been fixed and enabled for PPro - processors. The x86 port also better supports 64bit - operations now. - + MIPS has improved multiply/multiply-add support and now - includes mips16 ISA support. - + M68k has many micro-optimizations and Coldfire fixes. - * Core compiler is based on the GCC development tree from June 9, - 1998, so we have all of the [5]features found in GCC 2.8. - - [6]Return to the EGCS home page - - Last modified: September 4, 1999 - -References - - 1. http://gcc.gnu.org/onlinedocs/g77_news.html - 2. http://gcc.gnu.org/egcs-1.1/c++features.html - 3. http://gcc.gnu.org/news/gcse.html - 4. http://gcc.gnu.org/news/alias.html - 5. http://gcc.gnu.org/egcs-1.0/features-2.8.html - 6. http://gcc.gnu.org/index.html -====================================================================== -http://gcc.gnu.org/egcs-1.1/caveats.html - - EGCS 1.1 Caveats - - * EGCS has an integrated libstdc++, but does not have an integrated - libg++.

Changes since the - EGCS 1.0 release: - * Add support for Red Hat 5.0 Linux and better support for Linux - systems using glibc2. - Many programs failed to link when compiled with EGCS 1.0 on Red - Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1 - should fix these problems. - * Compatability with both EGCS 1.0 and GCC 2.8 libgcc exception - handling interfaces. - To avoid future compatibility problems, we strongly urge anyone - who is planning on distributing shared libraries that contain C++ - code to upgrade to EGCS 1.0.1 first. - Soon after EGCS 1.0 was released, the GCC developers made some - incompatible changes in libgcc's exception handling interfaces. - These changes were needed to solve problems on some platforms. - This means that GCC 2.8.0, when released, will not be seamlessly - compatible with shared libraries built by EGCS 1.0. The reason is - that the libgcc.a in GCC 2.8.0 will not contain a function needed - by the old interface. - The result of this is that there may be compatibility problems - with shared libraries built by EGCS 1.0 when used with GCC 2.8.0. - With EGCS 1.0.1, generated code uses the new (GCC 2.8.0) - interface, and libgcc.a has the support routines for both the old - and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be - freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely - mixed). - The maintainers of GCC 2.x have decided against including seamless - support for the old interface in 2.8.0, since it was never - "official", so to avoid future compatibility problems we recommend - against distributing any shared libraries built by EGCS 1.0 that - contain C++ code (upgrade to 1.0.1 and use that). - * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends. - The x86 changes fix code generation errors exposed when building - glibc2 and the Linux dynamic linker (ld.so). - The hppa change fixes a compiler abort when configured for use - with RTEMS. - The MIPS changes fix problems with the definition of LONG_MAX on - newer systems, allow for command line selection of the target ABI, - and fix one code generation problem. - The rs6000/ppc change fixes some problems with passing structures - to varargs/stdarg functions. - * A few machine independent bugfixes, mostly to fix code generation - errors when building Linux kernels or glibc. - * Fix a few critical exception handling and template bugs in the C++ - compiler. - * Fix Fortran namelist bug on alphas. - * Fix build problems on x86-solaris systems. - - An important goal of EGCS is to allow wide scale testing of new - features and optimizations which are still under development. However, - EGCS has been carefully tested and should be comparable in quality to - most GCC releases. - - EGCS 1.0.1 is based on an August 2, 1997 snapshot of the GCC 2.8 - development sources; it contains nearly all of the new features found - in GCC 2.8. - - EGCS also contains many improvements and features not found in GCC 2.7 - and even the soon to be released GCC 2.8 compilers. - * Integrated C++ runtime libraries, including support for most major - linux systems! - * The integrated libstdc++ library includes a verbatim copy of - [1]SGI's STL release. - * Integrated GNU Fortran compiler - * New instruction scheduler - * New alias analysis code - - See the [2]new features page for a more complete list of new features - found in EGCS 1.0.x releases. - - The EGCS 1.0.1 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.0.1 distribution).
