[libc] Add imaxabs Differential Revision: https://reviews.llvm.org/D129517 | 3 年前 | |
[libc] Initial support for darwin-aarch64. Add initial support for darwin-aarch64 (macOS M1). Some differences compared to linux-aarch64: - math.h defined math_errhandling by the compiler builtin __math_errhandling() but Apple Clang 13.0.0 on M1 does not support __math_errhandling() builtin as a macro function or a constexpr function. - math.h defines UNDERFLOW and OVERFLOW macros. - Besides 5 usual floating point exceptions: FE_INEXACT, FE_UNDERFLOW, FE_OVERFLOW, FE_DIVBYZERO, and FE_INVALID, fenv.h also has another floating point exception: FE_FLUSHTOZERO. The corresponding trap for FE_FLUSHTOZERO in the control register is at the different location compared to the status register. - FE_FLUSHTOZERO exception flag cannot be raised with the default CPU floating point operation mode.
