From 8d9e948652eb8381f1f376cbd0c9bc5e2947d150 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 18 Mar 2012 16:43:54 -0400 Subject: asm versions of some simple math functions for i386 and x86_64 these are functions that have direct fpu approaches to implementation without problematic exception or rounding issues. x86_64 lacks float/double versions because i'm unfamiliar with the necessary sse code for performing these operations. --- src/math/x86_64/fabsl.s | 6 ++++++ src/math/x86_64/rintl.s | 6 ++++++ 2 files changed, 12 insertions(+) create mode 100644 src/math/x86_64/fabsl.s create mode 100644 src/math/x86_64/rintl.s (limited to 'src/math/x86_64') diff --git a/src/math/x86_64/fabsl.s b/src/math/x86_64/fabsl.s new file mode 100644 index 00000000..4e7ab525 --- /dev/null +++ b/src/math/x86_64/fabsl.s @@ -0,0 +1,6 @@ +.global fabsl +.type fabsl,@function +fabsl: + fldt 8(%rsp) + fabs + ret diff --git a/src/math/x86_64/rintl.s b/src/math/x86_64/rintl.s new file mode 100644 index 00000000..64e663cd --- /dev/null +++ b/src/math/x86_64/rintl.s @@ -0,0 +1,6 @@ +.global rintl +.type rintl,@function +rintl: + fldt 8(%rsp) + frndint + ret -- cgit v1.2.1
