Subject: [PATCH 109/123] i386, x86_64, ppc: fix switch fallthrough cases with
|
|
GCC7
|
|
|
|
In util/getroot and efidisk slightly modify exitsing comment to mostly
|
|
retain it but still make GCC7 compliant with respect to fall through
|
|
annotation.
|
|
|
|
In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
|
|
upstream.
|
|
|
|
In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
|
|
suppress GCC7 warning.
|
|
|
|
In grub-core/gnulib/regexec.c use new __attribute__, because existing
|
|
annotation is not recognized by GCC7 parser (which requires that comment
|
|
immediately precedes case statement).
|
|
|
|
Otherwise add FALLTHROUGH comment.
|
|
|
|
Closes: 50598
