[PATCH] configs: Get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATED
This Kconfig option was removed during v4.19 development in
commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely
and for good")
so there's no point to keep it in defconfigs any longer.
FWIW defconfigs were patched with:

find . -name *_defconfig -exec sed -i '/CONFIG_ENABLE_WARN_DEPRECATED/d' {} \;

This was discussed at length in the C-Sky discussion. In short: the proper fix is to change that configure test to apply for cross compilation as well, other than in the very limited case where it tries to run something (but doing so is not appropriate in the current regression-fixes-only GCC development stage). You can hack around it with gcc_cv_initfini_array=yes for the target in config.gcc, as done by a few architectures. Or you can define the relevant target macros in gcc/config//.h to force init_array / fini_array use independent of the configure test, as done for AArch64. -- Joseph S.

Awesome, now I see how it was working for RISCV (config test printed "cached") and AArch64 I've added a local hack to gcc.config to test things out and will tackle this over at gcc mailing list. Many thx for untangling this for me. I found the C-Sky discussion as well [1] adding a link here for someone else in future who trips on this again. -Vineet [1] https://sourceware.org/ml/libc-alpha/2018-11/msg00870.html ___ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
[PATCH] [ARC]: Enable init_array support
gcc's common configure script has a subtle flaw that it only tests
{init,fini.preinit}_array support when NOT cross compiling. This causes
cross builds to erroneously deduce that the feature is not supported by
the target.
| host-gcc-final-ab544139bfee/build/gcc/config.log
|
|configure:22941: checking for .preinit_array/.init_array/.fini_array support
|configure:23106: checking cross compile... guessing
|configure:23111: result: no
The right fix is to enable this for *all* cross setups (and address any
fallouts). However in the short-term to enable ARC glibc port to upstream,
force enable this for ARC.
This has been discussed at length on glibc mailing list [1], [2]
