<pre>gcc trunk has a new warning -Wodr that reports odr violations when
building with -flto. It shows the following issue:
[278/983] Linking CXX shared library lib/libLLVMAnalysis.so
/var/tmp/llvm-project/llvm/lib/Analysis/InstructionSimplify.cpp:44:0: warning:
type ‘struct Query’ violates one definition rule [-Wodr]
struct Query {
^
/var/tmp/llvm-project/llvm/lib/Analysis/ValueTracking.cpp:65:0: note: a
different type is defined in another translation unit
struct Query {
^
/var/tmp/llvm-project/llvm/lib/Analysis/InstructionSimplify.cpp:45:21: note:
the first difference of corresponding definitions is field ‘DL’
const DataLayout *DL;
^
/var/tmp/llvm-project/llvm/lib/Analysis/ValueTracking.cpp:66:0: note: a field
with different name is defined in another translation unit
ExclInvsSet ExclInvs;
^
Unfortunately gcc crashes later in the build process. I will attach a full
list of odr violations once that ICE gets fixed.</pre>
