Bug ID: 91061
Summary: Enum type libcall_type violates the C++ One Definition
Rule
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: jamborm at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux
Target: x86_64-linux
When LTO-bootstrapping GCC with the D language, I get the following
warnings:
/home/mjambor/gcc/mine/src/gcc/d/runtime.cc:37:6: warning: type ‘libcall_type’
violates the C++ One Definition
Rule [-Wodr]
/home/mjambor/gcc/mine/src/gcc/rtl.h:4112:6: note: an enum with different value
name is defined in another tra
nslation unit
And a quick look confirms that is indeed the case. Of course, to
truly confuse the linker/LTO, you'd probably need also two functions
with the same name taking a parameter of that one shared name, but I
suppose it would be better not to wait for that to happen and adhere
to C++ rules anyway and rename one of the types.
Steps to reproduce:
Configure with --enable-languages=c,d,c++ and --with-build-config=bootstrap-lto
Run make and then go through the output.
