[Elan Ruusamäe]

hi

can someone have look at i686 and x32 builds (-r dev-7.3 branch)

Maybe this is some trace:

"checking whether to force non-PIC code in shared modules... yes"

x32 configure says "no" here.

Looks like wrong conditions in hand-written asm code.

Also I can see many warnings like:
Zend/zend_types.h:134:3: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
- to be verified if proper types are used during int/ptr arithmetic...

"checking whether to force non-PIC code in shared modules... yes"
x32 configure says "no" here.

it checks for $host_alias


yet that chunk has not changed since 2005

https://github.com/php/php-src/blob/php-7.3.0RC1/configure.ac#L297-L312




# Disable PIC mode by default where it is known to be safe to do so,

# to avoid the performance hit from the lost register

AC_MSG_CHECKING([whether to force non-PIC code in shared modules])

case $host_alias in

i?86-*-linux*|i?86-*-freebsd*)

if test "${with_pic+set}" != "set" || test "$with_pic" = "no"; then

with_pic=no

AC_MSG_RESULT(yes)

else

AC_MSG_RESULT(no)

fi

;;

*)

AC_MSG_RESULT(no)
