* Skip building libclang_rt when WITHOUT_CLANG is usedDimitry Andric2024-04-251-1/+1
| | | | | | | | | | | | | | | | | | | As noted in bug 277096, when building a pkgbase repository using WITHOUT_CROSS_COMPILER and WITHOUT_TOOLCHAIN (which sets WITHOUT_CLANG), the following residual files are left over: /usr/lib/clang/18/lib/freebsd/libclang_rt.asan-x86_64.so /usr/lib/clang/18/share/asan_ignore_list.txt /usr/lib/clang/18/share/cfi_ignore_list.txt /usr/lib/clang/18/share/msan_ignore_list.txt This is because the lib/libclang_rt directory is still descended into, even if WITHOUT_CLANG is used. Fix it by not descending into the libclang_rt directory in that case. PR: 277096 Reported by: Siva Mahadevan <me@svmhdvn.name> MFC after: 3 days

* pow,powf(3),__ieee754_rem_pio2(f): Avoid negative integer left shift UBKarl Tomlinson2024-04-234-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A compiler clever enough to know that z is positive with a non-zero biased exponent could, for example, optimize away the scalbnf(z,n) in pow() because behavior for left shift of negative values is undefined. `n` is negative when y*log2(|x|) < -0.5. i.e. |x^y| < sqrt(0.5) The intended behavior for operator<< in this code is to shift the two's complement representation of the first operand. In the pow() functions, the result is added to the IEEE 754 exponent of z = 2^y'. n may be negative enough to underflow the biased IEEE 754 exponent below zero, which is manifested in the sign bit of j (which would correspond to the IEEE 754 sign bit). The conversion from uint32_t to int32_t for out-of-int32_t-range values is implementation defined. The assumed behavior of interpreting the uint32_t value as a two's complement representation of a signed value is already assumed in many parts of the code, such as uses of GET_FLOAT_WORD() with signed integers. This code passes all the current tests, and makes some out of tree fuzzing tests pass again rather than hit UB (detailed in the commentary of the pull request).

* __vprintf(): switch from strerror() to strerror_rl()Konstantin Belousov2024-04-231-1/+5
| | | | | | | | | | | | | | | This eliminates the use of non-thread-safe function in printf*() family, and make the call locale-aware. Also, it stops obliterating the strerror() static buffer, which aligns with the POSIX requirement that implementations must behave as if no standard-mandated functions call strerror().

| | | | | | | | | | | | | | This version of swab function simplifies the logic of swapping adjacent bytes. Previous version of swab() used an arbitrary unrolling, which was relevant back in the day but unnecessary for modern compilers, as if the input size is known at compile time, they can do it automatically.
