For this to be fixed we'd need something similar to COLLECT_GCC_OPTIONS,
COLLECT_AS_OPTIONS for example, and lto-wrapper passing those on via
-Wa to the link-time driver.

This causes compilation of AVX code using GCC 4.9 to fail on OS X Mavericks;

Since this patch has been included in gcc10 (I verified it works now, but fails
with gcc9) can this issue be closed? Or does it need backporting to earlier
versions?

PR47785: Add support for handling Xassembler/Wa options with LTO.
Skip the test if arm7a is not supported at link time. This is the case
if the toolchain targets an M-profile CPU by default and does not have
A-profile multilib: the link step fails because it tries to mix
M-profile startup files with A-profile testcase.

--- Comment #21 from Thomas Weißschuh <gcc@t-8ch.de> ---
The commited fix produces false positives for assembler options that do not
influence the compilation output directly.
For example "-a=$FILE" to create assembler listings. (Whose target files have
to differ between different input files by design.)
