[Bug gas/14837] New: Variable passed to printf-like function without format argument

Please checkout hjl/lto/master branch at
http://git.kernel.org/?p=linux/kernel/git/hjl/binutils.git;a=summary
with GCC 4.7 and run LTO tests. If this fix is reverted, I got

After the fix, the error message becomes:

PASS: PR ld/12365
The difference is my_bcopy should be simply undefined, not defined in
a discarded section.

[Bug ld/12548] anonymous version scripts no longer working with binutils 2.21
http://sourceware.org/bugzilla/show_bug.cgi?id=12548
--- Comment #14 from Igor Pashev pashev.igor at gmail dot com 2012-11-13

I think I've fixed this.
The root of the problem is equivalent to this version script:
= 8
# Builtin:
base name {
global:
_PROCEDURE_LINKAGE_TABLE_;
_edata;
...
}
# Real mapfile:
{
...
}
= 8
So for anonymous version tag we just set base version: (See patch)
Test:
# cat test.c
int foo()
{
return 17;
}
const char *bar()
{
return bar;
}
# cat map
{
global:
foo;
local:
bar;
};
# gcc -fpic -c test.c -o lib.o -O0
# ld/ld-new -o lib.so lib.o -shared --version-script=map
# objdump -T lib.so
lib.so: file format elf64-x86-64-sol2
DYNAMIC SYMBOL TABLE:
0294 ld .text .text
00200308 gDO .dynamic _DYNAMIC
gDO .text _PROCEDURE_LINKAGE_TABLE_
002003b8 lDO .dynamic _END_
0294 lDO .text _START_
002003b8 gD .dynamic __bss_start
0294 gDF .text 000b foo
002003b8 gD .dynamic _edata
gDO .dynamic _GLOBAL_OFFSET_TABLE_
002003b8 gD .dynamic _end
