Bug ID: 91855
Summary: [8/9 Regression] OpenJDK Zero VM segfaults on SPARC
Product: gcc
Version: 9.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: glaubitz at physik dot fu-berlin.de

Target Milestone: ---
Target: sparc*-*-*
Building the Zero VM (interpreter-type VM) of OpenJDK on SPARC with gcc-8 or
gcc-9 results in the virtual machine segfaulting with:

(gdb)
This can be reproduced on gcc202 with:
$ mkdir openjdk
$ cd openjdk
$ wget https://hg.openjdk.java.net/jdk-updates/jdk11u/archive/tip.zip
$ unzip tip.zip
$ cd jdk11u-*
$ export CC=gcc-9 ; export CXX=g++-9 ; CONF=linux-sparcv9-normal-zero-release
MAKE_VERBOSE=y QUIETLY= LOG=debug make clean CONF=linux-sparcv9-zero-release ;
sh ./configure --with-jvm-variants=zero
--with-boot-jdk=/usr/lib/jvm/java-11-openjdk-sparc64/
--disable-precompiled-headers --disable-warnings-as-errors && make JOBS=64
MAKE_VERBOSE=y QUIETLY= LOG=debug CONF=linux-sparcv9-normal-zero-release
$ ./build/linux-sparcv9-normal-zero-release/jdk/bin/java
Segmentation fault
$
Setting CC=gcc-7 and CXX=g++-7 fixes the problem, so it must be a regression
with gcc-8 and gcc-9.
