+# gcc for VE
+
+gcc for VE is developed based on gcc (the GNU Compiler Collection) version 7.1.0.  
+User can compile a program for Vector Engine by using this software.  
+Please read this document carefully before use.
+
+##### What is VE
+
+VE stands for Vector Engine which is vector processors of [SX-Aurora TSUBASA](https://www.nec.com/en/global/solutions/hpc/sx/index.html). 
+
+
+## Notice
+
+  1. This software needs binutils for VE. It is available on the [SX-Aurora 
+     TSUBASA yum repository including SDK runtime](https://www.hpc.nec/repos/runtime/sdk/) for free.
+  2. This software can compile only C language.
+      - Only C compiler is available.
+  3. This software can't generate vector instructions.
+  4. It is required to use ncc, nc++, or nfort which are compilers for SX-Aurora 
+     TSUBASA to link objects compiled by ncc, nc++ or nfort.
+  5. This software is developed only for the purpose to build glibc for VE. 
+     Please note that NEC verified only the functionality required for it.
+  6. NEC doesn't support this software as the SX-Aurora TSUBASA product software.
+     Please note that NEC is not obligated to respond if user sends a bug report.  
+
+## Known Issues
+
+  1. A binary may malfunction when optimize options are enabled. In such case, 
+     use '-O0' option.
+  2. Gcc for VE is installed to /opt/nec/ve/bin/gcc.
+     When user set /opt/nec/ve/bin in $PATH before /usr/bin, /opt/nec/ve/bin/gcc
+     is invoked instead of /usr/bin/gcc.
+     - NEC MPI setup script adds /opt/nec/ve/bin into the head of $PATH. Therefore,
+       a build of VH side MPI program fails.
+     - A command expecting /usr/bin/gcc may invoke /opt/nec/ve/bin/gcc.
+
+##  Disclaimer
+
+  1. The contents of this document may change without prior notice.
+  2. NEC assumes no liability for any loss, including loss of earnings, 
+     arising from the use of this software.
+  3. This software is not intended for use in medical, nuclear, aerospace, mass
+     transit or other applications where human life may be at stake or high
+     reliability is required, nor is it intended for use in controlling such
+     applications. We disclaim liability for any personal injury and property
+     damages caused by such use of this software.
