kconfig: display recursive dependency resolution hint just once

2023-11-06T15:42:11+00:00

Commit 1c199f2878f6 ("kbuild: document recursive dependency limitation
/ resolution") probably intended to show a hint along with "recursive
dependency detected!" error, but it missed to add {...} guard, and the
hint is displayed in every loop of the dep_stack traverse, annoyingly.

This error was detected by GCC's -Wmisleading-indentation when switching
to build-time generation of lexer/parser.

scripts/kconfig/symbol.c: In function ‘sym_check_print_recursive’:
scripts/kconfig/symbol.c:1150:3: warning: this ‘if’ clause does not
guard... [-Wmisleading-indentation]
   if (stack->sym == last_sym)
   ^~
scripts/kconfig/symbol.c:1153:4: note: ...this statement, but the latter
is misleadingly indented as if it were guarded by the ‘if’
    fprintf(stderr, "For a resolution refer to
Documentation/kbuild/kconfig-language.txt\n");
    ^~~~~~~

I could simply add {...} to surround the three fprintf(), but I rather
chose to move the hint after the loop to make the whole message
readable.

kbuild: handle libs-y archives separately from built-in.o archives

2023-03-18T18:41:53+00:00

The thin archives build currently puts all lib.a and built-in.o
files together and links them with --whole-archive.

This works because thin archives can recursively refer to thin
archives. However some architectures include libgcc.a, which may
not be a thin archive, or it may not be constructed with the "P"
option, in which case its contents do not get linked correctly.

So don't pull .a libs into the root built-in.o archive. These
libs should already have symbol tables and indexes built, so they
can be direct linker inputs. Move them out of the --whole-archive
option, which restore the conditional linking behaviour of lib.a
to thin archives builds.

kbuild: thin archives use P option to ar

2023-03-18T18:41:50+00:00

The P option makes ar do full path name matching and can prevent ar
from discarding files with duplicate names in some cases of creating
thin archives from thin archives. The sh architecture in particular
loses some object files from its kernel/cpu/sh*/ directories without
this option.

This could be a bug in binutils ar, but the P option should not cause
any negative effects so it is safe to use to work around this with.

kbuild: thin archives for multi-y targets

2023-03-18T18:41:47+00:00

THIN_ARCHIVES builds archives for built-in.o targets, have it build
multi-y targets as archives as well.

This saves another ~15% of the size of intermediate artifacts in the
build tree. After this patch, the linker is only used in final link,
and special cases like vdsos.

kbuild: thin archives final link close --whole-archives option

2023-03-18T18:41:43+00:00

Close the --whole-archives option with --no-whole-archive. Some
architectures end up including additional .o and files multiple
times after this, and they get duplicate symbols when they are
brought under the --whole-archives option.

This matches more closely with the incremental final link.

kbuild: minor improvement for thin archives build

2023-03-18T18:41:39+00:00

The root built-in.o archive is currently generated before all object
files are built for the final link, due to final build of init/ after
version update. In practice it seems like it doesn't matter because
the archive symbol table does not change, but it is more logical to
create the final archive as the last step.

cert host tools: Stop complaining about deprecated OpenSSL functions

2022-11-01T15:30:41+00:00

OpenSSL 3.0 deprecated the OpenSSL's ENGINE API.  That is as may be, but
the kernel build host tools still use it.  Disable the warning about
deprecated declarations until somebody who cares fixes it.

arm64: build with baremetal linker target instead of Linux when available

2022-10-28T14:57:24+00:00

Not all toolchains have the baremetal elf targets, RedHat/Fedora ones
in particular. So, probe for whether it's available and use the previous
(linux) targets if it isn't.

kbuild: use HOSTLDFLAGS for single .c executables

2022-10-28T14:57:24+00:00

When compiling executables from a single .c file, the linker is also
invoked. Pass the HOSTLDFLAGS like for other linker commands.
