[Bug 1083498] Re: please enable arm assembler code in openssl

[Dmitrijs Ledkovs]

Armhf, nexus7, test
before: http://paste.ubuntu.com/5594566/
after: http://paste.ubuntu.com/5594567/

** Description changed:

- Imported from Debian bug http://bugs.debian.org/676533:
+ [Impact]
  
- Package: openssl
- Version: 1.0.1c-3
- Severity: wishlist
- Tags: patch
+  * Enable arm asm optimisations.
+  * This is an SRU as part of Hardware Enablement.
+ 
+ [Test Case]
+ 
+ * Compare `openssl speed` on armhf. There should be noticeable
+ improvement.
+ 
+ [Regression Potential]
+ 
+ * This change affects only arm[hf|el].
+ * The test-suite passes correctly.
+ 
+ [Other Info]
  
  Openssl has some rather nice arm assembler optimizations. For example
  on pandaboard (omap4430):
  
  benchmark    debian       with patch
  sha1         55836.67k -> 73599.08k
  aes-128 cbc  18451.11k -> 36305.34k
  aes-256 cbc  13552.30k -> 27108.31k
  sha256       20092.25k -> 43469.45k
  sha512       8052.74k  -> 37194.28k
  rsa 1024     1904.2v/S -> 3650.5v/s
- 
- The attached patch enables using arm assembler, as well as removes the
- armeb configuration as the armeb port is long dead.
