Subject: Re: PATCH: PR testsuite/42001: LTO tests fail with non multilib targets

Hello!

> LTO tests may pass -r to linker. "-lm" is always added automatically.
> For non multilib targets, linker may be called with "-r -lm" without

	PR testsuite/42001
	* gcc.dg/lto/lto.exp: Pass no-mathlib to lto_init.  Call
	lto_finish at the end.

The same change has to be applied to be applied to g++.dg/lto/lto.exp
and gfortran.dg/lto/lto.exp as well.

	PR testsuite/42001
	* g++.dg/lto/lto.exp: Pass no-mathlib to lto_init.  Call
	lto_finish at the end.
	* gfortran.dg/lto/lto.exp: Ditto.

Attached patch was tested on x86_64-pc-linux-gnu and
alphaev68-pc-linux-gnu, where it fixes several lto link failures.

Patch was committed to mainline as obvious.

Uros.
