This is aSoftFloat-3elibrary with additional build files targetting Linux armel.The intent behind this repository is to make building SoftFloat forOpenJDK onarm-sflt ABI easier.

Why

Software floating point math implementation on Linux on ARMslightly prefers performance over precision of calculations.This presented an issue for Java JCK - these imprecisions weredetected. The solution chosen by Java developers was to useSoftFloat-2b library for the problematic operations.

This repository provides an updated SoftFloat-3e library for newversions of OpenJDK, where SoftFloat support is added once again.(seeJDK-8215902).

How to use

  1. Install a suitable Linux ARM compiler and ensure thatarm-linux-gnueabi-gcc executable exists.
  2. Go tobuild/Linux-ARM-VFPv2-GCC-OpenJDK.
  3. Runmake
  4. Runmake DESTDIR=... install
  5. Configure OpenJDK with--with-sflt=... pointing to DESTDIR.
