Compiling memcpy-asm testcase from GCC testsuite with current GCC mainline and -O2 -flto results in call to my_memcpy that is not defined: ./xgcc -B ./ -O2 memops-asm*.c /abuild/jh/trunk-3/gcc/testsuite/gcc.c-torture/execute/builtins/lib/main.c -g -O0 -flto --save-temps -fdump-ipa-all-details -save-temps evans:/abuild/jh/trunk-3/build-inst2/gcc/:[0]# grep memcpy *.s ccNd9GvG.ltrans0.s: .globl memcpy ccNd9GvG.ltrans0.s: .type memcpy, @function ccNd9GvG.ltrans0.s:memcpy: ccNd9GvG.ltrans0.s: call my_memcpy.2055 ccNd9GvG.ltrans0.s: .size memcpy, .-memcpy ccNd9GvG.ltrans0.s: .type my_memcpy.2055, @function ccNd9GvG.ltrans0.s:my_memcpy.2055: ccNd9GvG.ltrans0.s: .size my_memcpy.2055, .-my_memcpy.2055 ccNd9GvG.ltrans0.s: call my_memcpy ccNd9GvG.ltrans0.s: call my_memcpy ccNd9GvG.ltrans0.s: .string "memcpy" ccNd9GvG.ltrans0.s: .string "my_memcpy" this is GCC bug where my_memcpy is once defined as alias and once as normal function and declarations are not merged. This however should result in linktime error instead of producing binary. In the binary the call to my_memcpy is linked to bogus destination: 400a41: e8 9c fb ff ff callq 4005e2 <a> I assume this is caused by fact that my_memcpy appears in original LTO symbol tables. Honza
Please provide a complete testcase.
Works for me on hjl/lto-mixed branch at http://git.kernel.org/?p=devel/binutils/hjl/x86.git;a=summary [hjl@gnu-32 testsuite]$ ../xgcc -B../ /export/gnu/import/git/gcc/gcc/testsuite/gcc.c-torture/execute/builtins/memops-asm*.c /export/gnu/import/git/gcc/gcc/testsuite/gcc.c-torture/execute/builtins/lib/main.c -O2 -fuse-linker-plugin -flto /tmp/ccUDWDxu.ltrans0.ltrans.o: In function `main': ccUDWDxu.ltrans0.o:(.text.startup+0x173): undefined reference to `my_bcopy' collect2: ld returned 1 exit status [hjl@gnu-32 testsuite]$
Hmm, wonder how testcases for linker plugin related bugs should look like. All I can think of is the GCC version + testcase that is in testsuite anyway.

Fixed for anything but common IR-only symbols. These will require a bit more work in the linker.
