FEnvImpl.h	[libc][NFC] Make explicit uint16_t casts in fenv	3 年前
FMA.h	[libc] Automatically add -mfma flag for architectures supporting FMA. Detect if the architecture supports FMA instructions and if the targets depend on fma. Reviewed By: gchatelet Differential Revision: https://reviews.llvm.org/D123615	4 年前
LongDoubleBits.h	[libc][nfc] update get_explicit_mantissa The get_explicit_mantissa function returns the mantissa of an FPBits floating point value with the implicit leading 1, if appropriate. This function existed previously, but did not handle non-normal numbers properly. Reviewed By: lntue Differential Revision: https://reviews.llvm.org/D129241	3 年前
NextAfterLongDouble.h	[libc] Replace type punning with bit_cast Although type punning is defined for union in C, it is UB in C++. This patch introduces a bit_cast function to convert between types in a safe way. This is necessary to get llvm-libc compile with GCC. This patch is extracted from D119002.

nearest_integer.h	[libc] Add float type and flag for nearest_integer to enable SSE4.2. Add float type and flag for nearest integer to automatically test with and without SSE4.2 flag. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D129916	3 年前
sqrt.h	[libc][obvious] fix sqrt when long double is double Previously, the "fsqrt" instruction was used on all x86_64 platforms for finding the square root of long doubles. On long double is double platforms (e.g. windows) this created errors. This patch changes square root function for long doubles to be the same as the one for doubles if long doubles are doubles.
