From 2ad4120746f401959637e467112cb768f945463d Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Sun, 11 Oct 2020 20:27:27 -0300 Subject: [PATCH] import elementary functions as intrinsics Importing them as intrinsics enables GCC to treat them as builtins whose behavior is known by GCC. Specifically, if they aren't intrinsics, calls to Sin and Cos won't be combined into sincos. We still need to make Sin and Cos wrappers inline in user-exposed interfaces to get users the benefit of this transformation. That is forthcoming in a separate patch. for gcc/ada/ChangeLog * libgnat/a-numaux.ads: Make all imports Intrinsic. * libgnat/a-numaux__darwin.ads: Likewise. * libgnat/a-numaux__libc-x86.ads: Likewise. * libgnat/a-numaux__vxworks.ads: Likewise. --- gcc/ada/libgnat/a-numaux.ads | 26 +++++++++++++------------- gcc/ada/libgnat/a-numaux__darwin.ads | 22 +++++++++++----------- gcc/ada/libgnat/a-numaux__libc-x86.ads | 26 +++++++++++++------------- gcc/ada/libgnat/a-numaux__vxworks.ads | 26 +++++++++++++------------- 4 files changed, 50 insertions(+), 50 deletions(-) diff --git a/gcc/ada/libgnat/a-numaux.ads b/gcc/ada/libgnat/a-numaux.ads index 3ad70671629..4154e1ab216 100644 --- a/gcc/ada/libgnat/a-numaux.ads +++ b/gcc/ada/libgnat/a-numaux.ads @@ -58,55 +58,55 @@ package Ada.Numerics.Aux is -- all as pure functions, because indeed all of them are in fact pure. function Sin (X : Double) return Double;
