> Aaah... You mean adding '-v' to 'xgcc', not to 'conftest' itself. My wrong.
Yup, sorry for being too vague.
> Please find the output of the following command attached.
The problem stems from "-lgcc --as-needed -lgcc_s_sparcv9 --no-as-needed -lc
-lgcc --as-needed -lgcc_s_sparcv9 --no-as-needed" passed to the linker. There
are probably undefined weak symbols in conftest that resolve to symbols in
libgcc_s. Could you run readelf --syms conftest | grep UND?
--as-needed/--no-as-needed has been introduced by the 2.15 linker and the
compiler autodetects it. Now, because Solaris doesn't use the --eh-frame-hdr
optimization, there are probably EH-related undefined weak symbols in every
single executable. The end result is that libgcc_s is always "needed", so the
default has effectively been switched from -static-libgcc to -shared-libgcc.
That's PR bootstrap/14992.
This has been correct in 4.x by:
