Test PR ld/12942 (3) in ld-plugins fails because the test, in ld/testsuite/ld-plugins/lto.exp, expects output: pr12942a.h:7: undefined reference to `link_error() but the actual output for i686-pc-linux-gnu, arm-none-eabi, arm-none-linux-gnueabi, and powerpc-linux-gnu is pr12942b.cc:(.text._Z4testv[_Z4testv]+0x14): undefined reference to `link_error()' The expected message is output if file pr12942b.cc is named in the link line, but the actual output is given when pr12942.o is used in the link line. Is this a bug in the linker or in the test? In addition, the test fails to link for arm-none-eabi with an undefined reference to abort. This can be fixed by replacing abort with __builtin_abort in the test source, as is done with other tests that are linked on bare-metal targets. The test was added by H.J. Lu.
Janis, I'll bet the reason you're seeing these failures is that you're building binutils with non-standard CFLAGS, specifically that your CFLAGS does not include -g. ld then doesn't have the info necessary to report the expected file and line number, and falls back to section/offset. This is clearly a bug in the testsuite.
I guess since the test is C++, I should have said CXXFLAGS rather than CFLAGS.
