On architectures that setup CROSS_COMPILE in their arch/*/Makefile
(arc, blackfin, m68k, mips, parisc, score, sh, tile, unicore32, xtensa),
cc-option and cc-disable-warning may check against the wrong compiler,
causing errors like
cc1: error: unrecognized command line option "-Wno-maybe-uninitialized"
if the host gcc supports a compiler option, while the cross compiler
doesn't support that option.
Move all logic using cc-option or cc-disable-warning below the inclusion
of the arch's Makefile to fix this.
Introduced by
- commit e74fc973b6e531fef1fce8b101ffff05ecfb774c ("Turn off
-Wmaybe-uninitialized when building with -Os"),
- commit 61163efae02040f66a95c8ed17f4407951ba58fa ("kbuild: LLVMLinux:
Add Kbuild support for building kernel with Clang").
As -Wno-maybe-uninitialized requires a quite recent gcc (gcc 4.6.3 on
Ubuntu 12.04 LTS doesn't support it), this only showed up recently (gcc
4.8.2 on Ubuntu 14.04 LTS does support it).
