2021-02-22runtime/POSIX: fix failures with glibc-2.33Jiri Slaby
commit 8ed005daf0ab of glibc-2.33 (Remove stat wrapper functions, move them to exported symbols) removed renames of `__fxstat`, `__xstat`, and `__lxstat` to `__fxstat64`, `__xstat64`, and `__lxstat64`, respectively. But we relied on the renames to build `fd_64.c` properly. With glibc 2.33, we now see link failures of the POSIX runtime: error: Linking globals named '__xstat': symbol multiply defined! Rename the functions using `__REDIRECT_NTH` in the code as `__USE_FILE_OFFSET64` case (which we define at the top of the file by `#define _FILE_OFFSET_BITS 64`) did exactly that. Fixes #1384.

2020-12-18fix cflags for runtime build typesJulian Büning
- `-DNDebug` -> `-DNDEBUG` - different flags for `Release{+Debug,}+Asserts` - `-g` is no longer part of common flags - `-D_DEBUG` is now only set for debug builds - removed unused `LIB_BC_FLAGS_{32,64}` - added example, architecture prefix for specific flags
2020-12-04Only build 32bit runtime libraries if supported by platformMartin Nowack
Automatically detect if 32bit bitcode files can be built. In this case, build runtime library with 32bit as well.

used.
2020-11-09Added fortified versions for the functions in the klee-libc libraryCristian Cadar
2020-11-09Since the runtime now contains fortified libc functions, it is important to ↵Cristian Cadar
compile it with -D_FORTIFY_SOURCE=0 to avoid infinite recursion.

2020-11-04[cmake] Add support to generate arbitrary runtime library configurationsMartin Nowack
Every runtime library can be build with multiple configurations. Replace the Makefile-based setup by cmake one. Currently, we generate 32bit and 64bit libraries simultaneously and can link against them.
2020-11-03fix: bcmp with n==0Alastair Reid
This was executing the loop when n==0 leading to an out of bound pointer error. Found while verifying Rust code that compares strings.

2020-08-28Definition of __cxa_thread_atexit_impl for the KLEE libc.Alastair Reid
This is a thread-local version of __cxa_atexit (but, in the absence of threads, it is sufficient to just call __cxa_atexit). The test is based on the existing test for atexit in test/Runtime/Uclibc/2008-03-04-libc-atexit-uses-dso-handle.c The motivation for adding this function is to support the Rust standard library that calls __cxa_thread_atexit_impl. This function is usually a weak symbol but, in KLEE, this behaves like a call to an unknown function and chaos ensues. Worse, it happens just as the program is cleanly shutting itself down, so programs that are cleanly exiting crash with the wrong message.
2020-08-07New intrinsic: klee_is_replayAlastair Reid
This instrinsic detects whether the program is being executed symbolically or concretely (i.e., using the libkleeRuntest library). The intended usage (illustrated in the test program) is to allow the test program to display the input values by invoking any libraries it wants to. This is especially valuable if you are constructing complex, structured values and for languages like Rust (or C++) that have rich libraries and print libraries. For example, you might pick a symbolic value N with the assumption "0 <= N < 10" and then pick N symbolic values and write them to an array. The resulting ktest file is a bit hard to understand compared with the output of the standard print function in Rust/C++.

2019-11-05Do not modify strings if they are read-only.Martin Nowack
Hoist increment of `sc` into the loop header. Memory locations can only be written to if they are writeable. Avoid concretising a value by writing it. If the location is not symbolic in the first place. This avoids writing read-only memory locations.
2019-11-05runtime: fix for glibc 2.30Jiri Slaby
glibc 2.30 moved definition of getdents64 to dirent_ext.h. Hence, it became visible to us (via dirent.h) and conflicts with our definition: runtime/POSIX/fd_64.c:112:5: error: conflicting types for 'getdents64' int getdents64(unsigned int fd, struct dirent *dirp, unsigned int count) { ^ /usr/include/bits/dirent_ext.h:29:18: note: previous declaration is here extern __ssize_t getdents64 (int __fd, void *__buffer, size_t __length) We use the parameters defined by kernel, not by userspace (libc). Both glibc and uclibc define it as: ssize_t __getdents64 (int fd, char *buf, size_t nbytes) so follow it.
