Bug #77318 [NEW]: php 7.3.0 is not LTO ready

From: kloczko dot tomasz at gmail dot com Operating system: Linux PHP version: 7.3.0 Package: *Compile Issues Bug Type: Bug Bug description:php 7.3.0 is not LTO ready Description: ------------ At the moment is not possible to use php if source code is not configured with --disable-gcc-global-regs an it is known fact. Betting that LTO optimisation may bring better seed improvement than --enable-gcc-global-regs I've been trying to build php using LTO optimisation. Looks like building php 7.3.0 with LTO optimisation fails on linking php cli: /bin/sh /home/tkloczko/rpmbuild/BUILD/php-7.3.0/build-cgi/libtool --silent --preserve-dup-deps --mode=link gcc
