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.

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.
