Yes, but those who build elfutils with -flto are likely using
-ffat-lto-objects if they build static libraries.
Yes, I can confirm that we do that as openSUSE, we actually build
with:
-flto -flto-partition=none -Wno-error=stack-usage= -ffat-lto-objects
As Dmitry pointed out you should now be able to drop both -flto-
partition=none an -Wno-error=stack-usage= (the linker will still warn,
but not error on the large stack-usage issues (we should probably still
fix them though).
Correct, I'm not using:
F="-O2 -g -Wall -flto=auto -ffat-lto-objects" && export CFLAGS="$F" && export CXXFLAGS="$F" &&
export LDFLAGS="$F" && ./configure
What do the test results look like? Do they all PASS with -ffat-lto-
objects?
Could you try the proposed patch for
https://sourceware.org/bugzilla/show_bug.cgi?id=27367
https://sourceware.org/pipermail/elfutils-devel/2021q4/004314.html
With the suggested patch (and BFD) all is green and shiny:
============================================================================
Testsuite summary for elfutils 0.185
