How much time and memory did compiling zend_execute.c take?

Just looking at top and my watch. Tested with -O2. CPU is Celeron 466Mhz with 384MB RAM. [yohgaki@dev HEAD]$ uname -a Linux dev.localnet 2.4.18-10k #1 Tue Mar 12 21:42:04 JST 2002 i686 unknown [yohgaki@dev HEAD]$ gcc -v Reading specs from /usr/lib/gcc-lib/i586-redhat-linux/2.96/specs gcc version 2.96 20000731 (Kondara MNU/Linux 2.1) Compiler used about 20MB and took about 30 seconds to compile it. -O3 does not make much difference. We need to test with GCC3 and other platforms, though. -- Yasuo Ohgaki

Hi all, It seems we are better have --enable-inline-optimization option after all. Andi told some "inline" directive has removed to make zend_execute.c work well with -O2. (I don't have problem with -O3 also) How about make inline optimization as default option? and have a --disable-inline-optimization option instead? Patch included. -- Yasuo Ohgaki /usr/bin/diff: conflicting specifications of output style
