Bug #23062	GCOV build: helper scripts missing in the BUILD directory

Category:	MySQL Server: Compiling	Severity:	S4 (Feature request)
Version:	5.0	OS:	Linux (Gentoo Linux AMD64)
Assigned to:	Marc ALFF	CPU Architecture:	Any

Description:
The only gcov script present under BUILD in 5.0 is :
./BUILD/compile-pentium-gcov

Since a GCOV build is required to test coverage as per the bug fix policy,
providing helper scripts for every platforms, or at least most popular platforms,
will be helpful.

In particular, Linux AMD64 + GCOV scripts are missing.

Expecting the fix to be checked-in every release currently under active support.

How to repeat:
inspect the content of the BUILD directory

Thank you for a problem report. Have you tried to use that 

vi BUILD/compile-pentium-gcov

on Linux running on AMD64? Why do you think it does not work properly. I checked other BUILD scripts, like compile-pentium-debug (that works on AMD, AFAIR), and see no difference in compile-pentium-gcov that can make it useless. Do you need any special flags that are not set up properly?

Adapting a script based on:
- ./BUILD/compile-pentium-gcov
- ./BUILD/compile-amd64-debug-max

works, but the issue is to avoid doing that for every clone / every user

I am assuming that current compile-amd64-* scripts exist for a reason,
which is why amd64-gcov (and -gprof by the way) should be present too.

Obviously, doing some research and adapting a script can be done,
so there is a work around.

The main concern is to facilitate tooling to *encourage* everyone to do
code coverage analysis during testing.

I think it is just a reasonable feature (new scripts) request then.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

  Bug#23062 (GCOV build: helper scripts missing in the BUILD directory)
  
  This patch provides compile helper scripts only,
  no server logic is affected.
  
  Before this patch, GCOV and GPROF build scripts were only provided for
  pentium platforms.
  
  With this patch, pentium, pentium64 and amd64 platforms have associated
  helper build scripts.
  
  The GCOV and GPROF specific compilation flags are set once in SETUP.sh,
  to avoid code duplication.

Pushed into 5.1.23-beta

Pushed into 5.0.50
