| | | | | | | | | | | | | | | | | | | __noreturn macro and modify the other exiting functions to use it. The __noreturn macro, unlike __dead2, must be used BEFORE the function. This is in line with the C and C++ specifications that place _Noreturn (c1x) and [[noreturn]] (C++11) in front of the functions. As with __dead2, this macro falls back to using the GCC attribute. Unfortunately, clang currently sets the same value for the C version macro in C99 and C1x modes, so these functions are hidden by default. At some point before 10.0, I need to go through the headers and clean up the C1x / C++11 visibility. Reviewed by: brooks (mentor) Notes: svn path=/head/; revision=228322

* Add two new routines: fdevname() and fdevname_r().Ed Schouten2009-02-111-0/+2
| | | | | | | | | | | | | | | | | A more elegant way of obtaining a name of a character device by its file descriptor on FreeBSD, is to use the FIODGNAME ioctl. Because a valid file descriptor implies a file descriptor is visible in /dev, it will always resolve a valid device name. I'm adding a more friendly wrapper for this ioctl, called fdevname(). It is a lot easier to use than devname() and also has better error handling. When a device name cannot be resolved, it will just return NULL instead of a generated device name that makes no sense.

* Add a function attribute called `__malloc_like', which informs gccDavid Schultz2009-01-311-2/+2
| | | | | | | | | | | | | | | | | that the annotated function returns a pointer that doesn't alias any extant pointer. This results in a 50%+ speedup in microbenchmarks such as the following: char *cp = malloc(1), *buf = malloc(BUF); for (i = 0; i < BUF; i++) buf[i] = *cp; In real programs, your mileage will vary. Note that gcc already performs this optimization automatically for any function called `malloc', `calloc', `strdup', or `strndup' unless -fno-builtins is used. Notes: svn path=/head/; revision=187961

* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

* Change the definition of NULL on ia64 (for LP64 compilations) fromMarcel Moolenaar2003-12-071-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an int constant to a long constant. This change improves consistency in the following two ways: 1. The first 8 arguments are always passed in registers on ia64, which by virtue of the generated code implicitly widens ints to longs and allows the use of an 32-bit integral type for 64-bit arguments. Subsequent arguments are passed onto the memory stack, which does not exhibit the same behaviour and consequently do not allow this. In practice this means that variadic functions taking pointers and given NULL (without cast) work as long as the NULL is passed in one of the first 8 arguments. A SIGSEGV is more likely the result if such would be done for stack-based arguments. This is due to the fact that the upper 4 bytes remain undefined. 2. All 64-bit platforms that FreeBSD supports, with the obvious exception of ia64, allow 32-bit integral types (specifically NULL) when 64-bit pointers are expected in variadic functions by way of how the compiler generates code. As such, code that works correctly (whether rightfully so or not) on any platform other than ia64, may fail on ia64. To more easily allow tweaking of the definition of NULL, this commit removes the 12 definitions in the various headers and puts it in a new header that can be included whenever NULL is to be made visible. This commit fixes GNOME, emacs, xemacs and a whole bunch of ports that I don't particularly care about at this time... Notes: svn path=/head/; revision=123257

Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.
