Gold linker, make test failures

Gold linker, make test failures

[Andrew Walrond]

Hello list,

I've been playing around trying to build the packages of our custom 
distro with the gold linker.

Two issues have arisen with version 2.21.51.0.1

Firstly, 'make test' fails when configured with 
'--enable-gold=both/gold', like this:

FAIL: flagstest_o_specialfile
PASS: flagstest_compress_debug_sections
FAIL: flagstest_o_specialfile_and_compress_debug_sections

I am using a vanilla gcc-4.5.1, and 'make test' works fine without 
--enable-gold.

Is this a known issue? I couldn't find anything on bugzilla except with 
respect to gcc 4-1. I'll add an entry unless there is a trivial answer 
to this.

Secondly, libtool fails it's own 'make check' when built with the gold 
linker. This is just a FYI; I can be more specific if it would be useful.

Yes, please be more specific (but send to the bug-libtool list if this
is about bugs *in* libtool).  We merged LTO some support in commit
v2.2.10-189-g9797b61, so you should be using at least Libtool 2.4.

Thanks,
Ralf

I'm not aware of any failure here specifically.

Note that only recent versions of gold linker will work when using a
fairly new glibc.  I'm not sure what version 2.21.51.0.1 is.  You need a
version of gold newer than 2010-08-19.
