Description:
------------
* make prof-clean
* run profile code with intermediate binary
* make prof-clean
* make prof-use

normally the binary is noticeable slower which is true for the whole PHP 7.0.x series

PHP 7.1.0RC6 was larger
PHP 7.1.0GA as expected
PHP 7.1.1 was larger
PHP 7.1.2RC was as expected
PHP 7.1.2GA is again larger

7.1.2RC1:
-rwxr-xr-x 1 root root 4,9M 2017-02-01 14:16 /usr/bin/php

7.1.2 GA:
-rwxr-xr-x 1 root root 5,4M 2017-02-16 12:41 /usr/bin/php

while the whole buildoutputs look OK (-fprofile-use in the second make) inluding the outputs and logs of the profiling scripts running our webapplication the size difference is very similar to a non PGO build and when it changes randomly between each upstream tarball it leaves a bad taste

BTW:
the release process is broken by design - in the rest of the world the last RC-tarball is just renamed and there are no commits between RC and GA release

7.1.8RC1 suffers from the same problem and NOW with 7.1.9-dev https://git.php.net/?p=php-src.git;a=snapshot;h=c48c638aeb130134345c7f5a7fd843f14ffb7e73;sf=tgz binary sizes are down to noraml values again - so nigle char in the build scripts changed

7.1.8RC1
-rwxr-xr-x 1 root root 4,4M 2017-07-21 14:06 /usr/bin/php
-rwxr-xr-x 1 root root 4,3M 2017-07-21 14:06 /usr/lib64/httpd/modules/libphp7.so

7.1.9-dev
-rwxr-xr-x 1 root root 3,9M 2017-07-30 13:15 /usr/bin/php
-rwxr-xr-x 1 root root 3,9M 2017-07-30 13:15 /usr/lib64/httpd/modules/libphp7.so

the sizes are in general lower than in the initial report because more extensions are built shared but you can clearly see the difference above
____________________________________

compared to PHP 7.0.21 below (exactly same build config) 7.1 is no longer that bloated and given that binaries are always stripped (strip -s --strip-unneeded) at the end of the rpmbuild i really have no idea what's going on here

7.0.21:
-rwxr-xr-x 1 root root 3,7M 2017-07-05 18:27 /usr/lib64/httpd/modules/libphp7.so
