| 12 | February 24, 2004
|
|---|
| 13 |
|
|---|
| 14 | The [1]GNU project and the GCC developers are pleased to announce the
|
|---|
| 15 | release of GCC 3.3.3. This release was actually completed on February
|
|---|
| 16 | 14, but technical issues with the transition to new security measures
|
|---|
| 17 | for protecting FSF servers required a delay in the announcement.
|
|---|
| 18 |
|
|---|
| 19 | The GCC 3.3 release series includes numerous [2]new features,
|
|---|
| 20 | improvements, bug fixes, and other changes, thanks to an [3]amazing
|
|---|
| 21 | group of volunteers.

| 39 | GCC used to stand for the GNU C Compiler, but since the compiler
|
|---|
| 40 | supports several other languages aside from C, it now stands for the
|
|---|
| 41 | GNU Compiler Collection.
|
|---|
| 42 |
|
|---|
| 43 | A list of [8]successful builds is updated as new information becomes
|
|---|
| 44 | available.
|
|---|
| 45 |
|
|---|
| 46 | The GCC developers would like to thank the numerous people that have
|
|---|
| 47 | contributed new features, improvements, bug fixes, and other changes
|
|---|
| 48 | as well as test results to GCC. This [9]amazing group of volunteers is
|
|---|
| 49 | what makes GCC successful.

| 106 | GCC 3.3 Release Series
|
|---|
| 107 | Changes, New Features, and Fixes
|
|---|
| 108 |
|
|---|
| 109 | The latest release in the 3.3 release series is [1]GCC 3.3.3.
|
|---|
| 110 |
|
|---|
| 111 | Caveats
|
|---|
| 112 |
|
|---|
| 113 | * The preprocessor no longer accepts multi-line string literals.
|
|---|
| 114 | They were deprecated in 3.0, 3.1, and 3.2.
|
|---|
| 115 | * The preprocessor no longer supports the -A- switch when appearing
|
|---|
| 116 | alone. -A- followed by an assertion is still supported.
|
|---|
| 117 | * Support for all the systems [2]obsoleted in GCC 3.1 has been
|
|---|
| 118 | removed from GCC 3.3. See below for a [3]list of systems which are
|
|---|
| 119 | obsoleted in this release.
|
|---|
| 120 | * Checking for null format arguments has been decoupled from the
|
|---|
| 121 | rest of the format checking mechanism. Programs which use the
|
|---|
| 122 | format attribute may regain this functionality by using the new
|
|---|
| 123 | [4]nonnull function attribute. Note that all functions for which
|
|---|
| 124 | GCC has a built-in format attribute, an appropriate built-in
|
|---|
| 125 | nonnull attribute is also applied.
|
|---|
| 126 | * The DWARF (version 1) debugging format has been deprecated and
|
|---|
| 127 | will be removed in a future version of GCC. Version 2 of the DWARF
|
|---|
| 128 | debugging format will continue to be supported for the foreseeable
|
|---|
| 129 | future.
|
|---|
| 130 | * The C and Objective-C compilers no longer accept the "Naming
|
|---|
| 131 | Types" extension (typedef foo = bar); it was already unavailable
|
|---|
| 132 | in C++. Code which uses it will need to be changed to use the
|
|---|
| 133 | "typeof" extension instead: typedef typeof(bar) foo. (We have
|
|---|
| 134 | removed this extension without a period of deprecation because it
|
|---|
| 135 | has caused the compiler to crash since version 3.0 and no one
|
|---|
| 136 | noticed until very recently. Thus we conclude it is not in
|
|---|
| 137 | widespread use.)
|
|---|
| 138 | * The -traditional C compiler option has been removed. It was
|
|---|
| 139 | deprecated in 3.1 and 3.2. (Traditional preprocessing remains
|
|---|
| 140 | available.) The <varargs.h> header, used for writing variadic
|
|---|
| 141 | functions in traditional C, still exists but will produce an error
|
|---|
| 142 | message if used.
|
|---|
| 143 | * GCC 3.3.1 automatically places zero-initialized variables in the
|
|---|
| 144 | .bss section on some operating systems. Versions of GNU Emacs up
|
|---|
| 145 | to (and including) 21.3 will not work correctly when using this
|
|---|
| 146 | optimization; you can use -fno-zero-initialized-in-bss to disable
|
|---|
| 147 | it.
|
|---|
| 148 |
|
|---|
| 149 | General Optimizer Improvements
|
|---|
| 150 |
|
|---|
| 151 | * A new scheme for accurately describing processor pipelines, the
|
|---|
| 152 | [5]DFA scheduler, has been added.
|
|---|
| 153 | * Pavel Nejedly, Charles University Prague, has contributed new file
|
|---|
| 154 | format used by the edge coverage profiler (-fprofile-arcs).
|
|---|
| 155 | The new format is robust and diagnoses common mistakes where
|
|---|
| 156 | profiles from different versions (or compilations) of the program
|
|---|
| 157 | are combined resulting in nonsensical profiles and slow code to
|
|---|
| 158 | produced with profile feedback. Additionally this format allows
|
|---|
| 159 | extra data to be gathered. Currently, overall statistics are
|
|---|
| 160 | produced helping optimizers to identify hot spots of a program
|
|---|
| 161 | globally replacing the old intra-procedural scheme and resulting
|
|---|
| 162 | in better code. Note that the gcov tool from older GCC versions
|
|---|
| 163 | will not be able to parse the profiles generated by GCC 3.3 and
|
|---|
| 164 | vice versa.
|
|---|
| 165 | * Jan Hubicka, SuSE Labs, has contributed a new superblock formation
|
|---|
| 166 | pass enabled using -ftracer. This pass simplifies the control flow
|
|---|
| 167 | of functions allowing other optimizations to do better job.
|
|---|
| 168 | He also contributed the function reordering pass
|
|---|
| 169 | (-freorder-functions) to optimize function placement using profile
|
|---|
| 170 | feedback.
|
|---|
| 171 |
|
|---|
| 172 | New Languages and Language specific improvements
|
|---|
| 173 |
|
|---|
| 174 | C/ObjC/C++
|
|---|
| 175 |
|
|---|
| 176 | * The preprocessor now accepts directives within macro arguments. It
|
|---|
| 177 | processes them just as if they had not been within macro
|
|---|
| 178 | arguments.
|
|---|
| 179 | * The separate ISO and traditional preprocessors have been
|
|---|
| 180 | completely removed. The front end handles either type of
|
|---|
| 181 | preprocessed output if necessary.
|
|---|
| 182 | * In C99 mode preprocessor arithmetic is done in the precision of
|
|---|
| 183 | the target's intmax_t, as required by that standard.
|
|---|
| 184 | * The preprocessor can now copy comments inside macros to the output
|
|---|
| 185 | file when the macro is expanded. This feature, enabled using the
|
|---|
| 186 | -CC option, is intended for use by applications which place
|
|---|
| 187 | metadata or directives inside comments, such as lint.
|
|---|
| 188 | * The method of constructing the list of directories to be searched
|
|---|
| 189 | for header files has been revised. If a directory named by a -I
|
|---|
| 190 | option is a standard system include directory, the option is
|
|---|
| 191 | ignored to ensure that the default search order for system
|
|---|
| 192 | directories and the special treatment of system header files are
|
|---|
| 193 | not defeated.
|
|---|
| 194 | * A few more [6]ISO C99 features now work correctly.
|
|---|
| 195 | * A new function attribute, nonnull, has been added which allows
|
|---|
| 196 | pointer arguments to functions to be specified as requiring a
|
|---|
| 197 | non-null value. The compiler currently uses this information to
|
|---|
| 198 | issue a warning when it detects a null value passed in such an
|
|---|
| 199 | argument slot.
|
|---|
| 200 | * A new type attribute, may_alias, has been added. Accesses to
|
|---|
| 201 | objects with types with this attribute are not subjected to
|
|---|
| 202 | type-based alias analysis, but are instead assumed to be able to
|
|---|
| 203 | alias any other type of objects, just like the char type.
|
|---|
| 204 |
|
|---|
| 205 | C++
|
|---|
| 206 |
|
|---|
| 207 | * Type based alias analysis has been implemented for C++ aggregate
|
|---|
| 208 | types.
|
|---|
| 209 |
|
|---|
| 210 | Objective-C
|
|---|
| 211 |
|
|---|
| 212 | * Generate an error if Objective-C objects are passed by value in
|
|---|
| 213 | function and method calls.
|
|---|
| 214 | * When -Wselector is used, check the whole list of selectors at the
|
|---|
| 215 | end of compilation, and emit a warning if a @selector() is not
|
|---|
| 216 | known.
|
|---|
| 217 | * Define __NEXT_RUNTIME__ when compiling for the NeXT runtime.
|
|---|
| 218 | * No longer need to include objc/objc-class.h to compile self calls
|
|---|
| 219 | in class methods (NeXT runtime only).
|
|---|
| 220 | * New -Wundeclared-selector option.
|
|---|
| 221 | * Removed selector bloating which was causing object files to be 10%
|
|---|
| 222 | bigger on average (GNU runtime only).
|
|---|
| 223 | * Using at run time @protocol() objects has been fixed in certain
|
|---|
| 224 | situations (GNU runtime only).
|
|---|
| 225 | * Type checking has been fixed and improved in many situations
|
|---|
| 226 | involving protocols.
|
|---|
| 227 |
|
|---|
| 228 | Java
|
|---|
| 229 |
|
|---|
| 230 | * The java.sql and javax.sql packages now implement the JDBC 3.0
|
|---|
| 231 | (JDK 1.4) API.
|
|---|
| 232 | * The JDK 1.4 assert facility has been implemented.
|
|---|
| 233 | * The bytecode interpreter is now direct threaded and thus faster.
|
|---|
| 234 |
|
|---|
| 235 | Fortran
|
|---|
| 236 |
|
|---|
| 237 | * Fortran improvements are listed in [7]the Fortran documentation.
|
|---|
| 238 |
|
|---|
| 239 | Ada
|
|---|
| 240 |
|
|---|
| 241 | * Ada tasking now works with glibc 2.3.x threading libraries.
|
|---|
| 242 |
|
|---|
| 243 | New Targets and Target Specific Improvements
|
|---|
| 244 |
|
|---|
| 245 | * The following changes have been made to the HP-PA port:
|
|---|
| 246 | + The port now defaults to scheduling for the PA8000 series of
|
|---|
| 247 | processors.
|
|---|
| 248 | + Scheduling support for the PA7300 processor has been added.
|
|---|
| 249 | + The 32-bit port now supports weak symbols under HP-UX 11.
|
|---|
| 250 | + The handling of initializers and finalizers has been improved
|
|---|
| 251 | under HP-UX 11. The 64-bit port no longer uses collect2.
|
|---|
| 252 | + Dwarf2 EH support has been added to the 32-bit linux port.
|
|---|
| 253 | + ABI fixes to correct the passing of small structures by
|
|---|
| 254 | value.
|
|---|
| 255 | * The SPARC, HP-PA, SH4, and x86/pentium ports have been converted
|
|---|
| 256 | to use the DFA processor pipeline description.
|
|---|
| 257 | * The following NetBSD configurations for the SuperH processor
|
|---|
| 258 | family have been added:
|
|---|
| 259 | + SH3, big-endian, sh-*-netbsdelf*
|
|---|
| 260 | + SH3, little-endian, shle-*-netbsdelf*
|
|---|
| 261 | + SH5, SHmedia, big-endian, 32-bit default, sh5-*-netbsd*
|
|---|
| 262 | + SH5, SHmedia, little-endian, 32-bit default, sh5le-*-netbsd*
|
|---|
| 263 | + SH5, SHmedia, big-endian, 64-bit default, sh64-*-netbsd*
|
|---|
| 264 | + SH5, SHmedia, little-endian, 64-bit default, sh64le-*-netbsd*
|
|---|
| 265 | * The following changes have been made to the IA-32/x86-64 port:
|
|---|
| 266 | + SSE2 and 3dNOW! intrinsics are now supported.
|
|---|
| 267 | + Support for thread local storage has been added to the IA-32
|
|---|
| 268 | and x86-64 ports.
|
|---|
| 269 | + The x86-64 port has been significantly improved.
|
|---|
| 270 | * The following changes have been made to the MIPS port:
|
|---|
| 271 | + All configurations now accept the -mabi switch. Note that you
|
|---|
| 272 | will need appropriate multilibs for this option to work
|
|---|
| 273 | properly.
|
|---|
| 274 | + ELF configurations will always pass an ABI flag to the
|
|---|
| 275 | assembler, except when the MIPS EABI is selected.
|
|---|
| 276 | + -mabi=64 no longer selects MIPS IV code.
|
|---|
| 277 | + The -mcpu option, which was deprecated in 3.1 and 3.2, has
|
|---|
| 278 | been removed from this release.
|
|---|
| 279 | + -march now changes the core ISA level. In previous releases,
|
|---|
| 280 | it would change the use of processor-specific extensions, but
|
|---|
| 281 | would leave the core ISA unchanged. For example, mips64-elf
|
|---|
| 282 | -march=r8000 will now generate MIPS IV code.
|
|---|
| 283 | + Under most configurations, -mipsN now acts as a synonym for
|
|---|
| 284 | -march.
|
|---|
| 285 | + There are some new preprocessor macros to describe the -march
|
|---|
| 286 | and -mtune settings. See the documentation of those options
|
|---|
| 287 | for details.
|
|---|
| 288 | + Support for the NEC VR-Series processors has been added. This
|
|---|
| 289 | includes the 54xx, 5500, and 41xx series.
|
|---|
| 290 | + Support for the Sandcraft sr71k processor has been added.
|
|---|
| 291 | * The following changes have been made to the S/390 port:
|
|---|
| 292 | + Support to build the Java runtime libraries has been added.
|
|---|
| 293 | Java is now enabled by default on s390-*-linux* and
|
|---|
| 294 | s390x-*-linux* targets.
|
|---|
| 295 | + Multilib support for the s390x-*-linux* target has been
|
|---|
| 296 | added; this allows to build 31-bit binaries using the -m31
|
|---|
| 297 | option.
|
|---|
| 298 | + Support for thread local storage has been added.
|
|---|
| 299 | + Inline assembler code may now use the 'Q' constraint to
|
|---|
| 300 | specify memory operands without index register.
|
|---|
| 301 | + Various platform-specific performance improvements have been
|
|---|
| 302 | implemented; in particular, the compiler now uses the BRANCH
|
|---|
| 303 | ON COUNT family of instructions and makes more frequent use
|
|---|
| 304 | of the TEST UNDER MASK family of instructions.
|
|---|
| 305 | * The following changes have been made to the PowerPC port:
|
|---|
| 306 | + Support for IBM Power4 processor added.
|
|---|
| 307 | + Support for Motorola e500 SPE added.
|
|---|
| 308 | + Support for AIX 5.2 added.
|
|---|
| 309 | + Function and Data sections now supported on AIX.
|
|---|
| 310 | + Sibcall optimizations added.
|
|---|
| 311 | * The support for H8 Tiny is added to the H8/300 port with -mn.
|
|---|
| 312 |
|
|---|
| 313 | Obsolete Systems
|
|---|
| 314 |
|
|---|
| 315 | Support for a number of older systems has been declared obsolete in
|
|---|
| 316 | GCC 3.3. Unless there is activity to revive them, the next release of
|
|---|
| 317 | GCC will have their sources permanently removed.
|
|---|
| 318 |
|
|---|
| 319 | All configurations of the following processor architectures have been
|
|---|
| 320 | declared obsolete:
|
|---|
| 321 | * Matsushita MN10200, mn10200-*-*
|
|---|
| 322 | * Motorola 88000, m88k-*-*
|
|---|
| 323 | * IBM ROMP, romp-*-*
|
|---|
| 324 |
|
|---|
| 325 | Also, some individual systems have been obsoleted:
|
|---|
| 326 | * Alpha
|
|---|
| 327 | + Interix, alpha*-*-interix*
|
|---|
| 328 | + Linux libc1, alpha*-*-linux*libc1*

| 387 | Documentation improvements
|
|---|
| 388 |
|
|---|
| 389 | Other significant improvements
|
|---|
| 390 |
|
|---|
| 391 | * Almost all front-end dependencies in the compiler have been
|
|---|
| 392 | separated out into a set of language hooks. This should make
|
|---|
| 393 | adding a new front end clearer and easier.
|
|---|
| 394 | * One effect of removing the separate preprocessor is a small
|
|---|
| 395 | increase in the robustness of the compiler in general, and the
|
|---|
| 396 | maintainability of target descriptions. Previously target-specific
|
|---|
| 397 | built-in macros and others, such as __FAST_MATH__, had to be
|
|---|
| 398 | handled with so-called specs that were hard to maintain. Often
|
|---|
| 399 | they would fail to behave properly when conflicting options were
|
|---|
| 400 | supplied on the command line, and define macros in the user's
|
|---|
| 401 | namespace even when strict ISO compliance was requested.
|
|---|
| 402 | Integrating the preprocessor has cleanly solved these issues.
|
|---|
| 403 | * The Makefile suite now supports redirection of make install by
|
|---|
| 404 | means of the variable DESTDIR.
