Bug ID: 100812
Summary: [10 Regression] lto1-wpa memory hog building openjdk
trunk
Product: gcc
Version: 10.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
openjdk trunk was building ok with lto (at least the 17+19 snapshot), however
with the 17+24 snapshot, one lto1-wpa process is eating up memory to 200GB and
beyond (linking libjvm.so). seen with the gcc-10 branch. The 17+24 snapshot
builds ok with the gcc-11 branch.
openjdk is configured with
./configure \
--with-jvm-variants=server \
--with-boot-jdk=/usr/lib/jvm/java-17-openjdk-amd64 \
--disable-precompiled-headers --with-jvm-features=zgc \
--with-extra-cflags='-flto=auto -ffat-lto-objects' \
--with-extra-cxxflags='-flto=auto -ffat-lto-objects' \
--with-extra-ldflags='-flto=auto' \
--disable-warnings-as-errors \
--with-debug-level=release \
--with-native-debug-symbols=internal \
--enable-unlimited-crypto \
--disable-javac-server \
--with-stdc++lib=dynamic
