Bug ID: 70839
Summary: [6/7 regression] Every libjava execution test FAILs:
Incorrect library ABI version detected
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: java
Assignee: unassigned at gcc dot gnu.org

proposed patch
Since the 6.1.0 release, every single libjava execution test FAILs everywhere
(seen on Solaris/x86, Linux/x86_64, and Darwin/x86):
libgcj failure: gcj linkage error.
Incorrect library ABI version detected. Aborting.
The message is from libjava/java/lang/natClassLoader.cc (_Jv_CheckABIVersion)
which (on i386-pc-solaris2.12) is called like this:
#0 _Jv_CheckABIVersion (value=1074342824)

The version == GCJ_CXX_ABI_VERSION test fails: the latter is (from
libjava/include/jvm.h)
#define GCJ_CXX_ABI_VERSION (__GNUC__ * 100000)
Before the release, version was 600000, since then it's 601000.
In libjava/java/lang/natClassLoader.c (_Jv_RegisterClasses) we have
_Jv_CheckABIVersion ((unsigned long) klass->next_or_version);
where klass->next_or_version is set in gcc/java/class.c (make_class_data):
PUSH_FIELD_VALUE (v2, "next_or_version", gcj_abi_version);
Ultimately, gcc/java/decl.c (parse_version) sets gcj_abi_version from
version_string and still extracts the minor version, while this libjava
change
2016-01-03 Matthias Klose <d...@ubuntu.com>
* libtool-version: Bump soversion.
* include/jvm.h (GCJ_CXX_ABI_VERSION): Don't encode __GNUC_MINOR__.
doesn't expect the minor version any longer.
The attached patch gets rid of the minor version in jc1, too and seems to fix
the errors (x86_64-apple-darwin15.5.0 libjava make check still running).
