Documentation/llvm: update IRC location

This should have been done with commit 91ed3ed0f798 ("MAINTAINERS: update ClangBuiltLinux IRC chat") but I did not realize it was in two separate spots.

scripts/Makefile.clang: default to LLVM_IAS=1

2021-08-10T00:13:25+00:00

LLVM_IAS=1 controls enabling clang's integrated assembler via -integrated-as. This was an explicit opt in until we could enable assembler support in Clang for more architecures. Now we have support and CI coverage of LLVM_IAS=1 for all architecures except a few more bugs affecting s390 and powerpc. This commit flips the default from opt in via LLVM_IAS=1 to opt out via LLVM_IAS=0. CI systems or developers that were previously doing builds with CC=clang or LLVM=1 without explicitly setting LLVM_IAS must now explicitly opt out via LLVM_IAS=0, otherwise they will be implicitly opted-in. This finally shortens the command line invocation when cross compiling with LLVM to simply: $ make ARCH=arm64 LLVM=1 Signed-off-by: Nick Desaulniers Reviewed-by: Nathan Chancellor Signed-off-by: Masahiro Yamada

Documentation/llvm: update CROSS_COMPILE inferencing

2021-08-10T00:13:25+00:00

As noted by Masahiro, document how we can generally infer CROSS_COMPILE (and the more specific details about --target and --prefix) based on ARCH. Change use of env vars to command line parameters.

kconfig: change "modules" from sub-option to first-level attribute

Now "modules" is the only member of the "option" property. Remove "option", and move "modules" to the top level property. Signed-off-by: Masahiro Yamada

kconfig: change defconfig_list option to environment variable

2021-04-14T06:22:48+00:00

"defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada
