Conklin <jtc@wimsey.com> 01/17/95. 354 // Public domain. 355 356 // Macro to test if we're using a specific version of gcc or later. 357 358 // The __CONCAT macro is used to concatenate parts of symbol names, e.g. 359 // with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo. 360 // The __CONCAT macro is a bit tricky -- make sure you don't put spaces 361 // in between its arguments. Do not use __CONCAT on double-quoted strings, 362 // such as those from the __STRING macro: to concatenate strings just put 363 // them next to each other. 364 365 // GCC1 and some versions of GCC2 declare dead (non-returning) and 366 // pure (no side effects) functions using "volatile" and "const"; 367 // unfortunately, these then cause warnings under "-ansi -pedantic". 368 // GCC >= 2.5 uses the __attribute__((attrs)) style. All of these 369 // work for GNU C++ (modulo a slight glitch in the C++ grammar in 370 // the distribution version of 2.5.5). 371 372 // __returns_twice makes the compiler not assume the function 373 // only returns once. This affects registerisation of variables: 374 // even local variables need to be in memory across such a call. 375 // Example: setjmp() 376 377 // __only_inline makes the compiler only use this function definition 378 // for inlining; references that can't be inlined will be left as 379 // external references instead of generating a local copy. The 380 // matching library should include a simple extern definition for 381 // the function to handle those references. c.f. ctype.h 382 383 // GNU C version 2.96 adds explicit branch prediction so that 384 // the CPU back-end can hint the processor and also so that 385 // code blocks can be reordered such that the predicted path 386 // sees a more linear flow, thus improving cache behavior, etc. 387 // 388 // The following two macros provide us with a way to utilize this 389 // compiler feature. Use __predict_true() if you expect the expression 390 // to evaluate to true, and __predict_false() if you expect the 391 // expression to evaluate to false. 392 // 393 // A few notes about usage: 394 // 395 // * Generally, __predict_false() error condition checks (unless 396 // you have some _strong_ reason to do otherwise, in which case 397 // document it), and/or __predict_true() `no-error' condition 398 // checks, assuming you want to optimize for the no-error case. 399 // 400 // * Other than that, if you don't know the likelihood of a test 401 // succeeding from empirical or other `hard' evidence, don't 402 // make predictions. 403 // 404 // * These are meant to be used in places that are run `a lot'. 405 // It is wasteful to make predictions in code that is run 406 // seldomly (e.g. at subsystem initialization time) as the 407 // basic block reordering that this affects can often generate 408 // larger code. 409 410 // Delete pseudo-keywords wherever they are not available or needed. 411 412 // The __packed macro indicates that a variable or structure members 413 // should have the smallest possible alignment, despite any host CPU 414 // alignment requirements. 415 // 416 // The __aligned(x) macro specifies the minimum alignment of a 417 // variable or structure. 418 // 419 // These macros together are useful for describing the layout and 420 // alignment of messages exchanged with hardware or other systems. 421 422 // "The nice thing about standards is that there are so many to choose from." 423 // There are a number of "feature test macros" specified by (different) 424 // standards that determine which interfaces and types the header files 425 // should expose. 426 // 427 // Because of inconsistencies in these macros, we define our own 428 // set in the private name space that end in _VISIBLE.
