2025-05-11 Thread Yuao Ma
Hi all, According to the Fortran standard, atand(y, x) is equivalent to atan2d(y, x). However, the current atand(y, x) function produces an error. This patch includes the necessary intrinsic mapping, related test, and intrinsic documentation. The minor comment change in intrinsic.cc is cherry-pick

Hi all, This patch adds trigonometric pi-based functions as gcc builtins: acospi, asinpi, atan2pi, atanpi, cospi, sinpi, and tanpi. Latest glibc already provides support for these functions, which we plan to leverage in future gfortran implementations. The patch includes two test cases to verify

Hi all, This patch has been updated to conditionally fold the specified math functions only when using MPFR version 4.2.0 or newer. To accompany this change, the test case now utilizes `__builtin_constant_p` to determine whether to execute the tests against the folded functions. Let me know if t
