[PATCH 0/2] -fcanon-file-prefix and cc-rs compiler flag mixing

[Gyorgy Sarvari]

These two commits are very losely related to each other.

Patch 1 adds -fcanon-prefix-map to the compiler flags, when it is applicable 
(when gcc >=13 is used). This helps with finding the correct debug sources 
for the -src package. Without this flag some recipes miss some source 
files from this package, and sometimes they miss all files. (E.g. sqlite, audiofile, librsvg)

Patch 2 tries to work around a bug (or at least unexpected behavior) in the cc-rs 
crate. 

This patch tries to recognize if there are any flags passed to the compiler that shouldn't be there.

How these patches are related: normally the *-prefix-map flags are only passed to cross-compiled 
targets. However the cc crate passes this flag to the native builds also (due to flag 
merging), and in case the host compiler is too old to recognize this flag, than the build fails.

Though I was able to build rust with both of these patches for both native and class targets,
I wasn't able to configure qemu to run in my docker env, and due to this I was unable
to verify if the selftests pass in an OS where gcc is older than v13.

While not mentioned explicitly, but especially with the 2nd patch I'm testing the waters,
it is an RFC also.

[PATCH 1/2] bitbake.conf, gcc toolchain: add -fcanon-prefix-map to map-prefixes

[Gyorgy Sarvari]

This patch adds -fcanon-prefix-map to the list of compile file-prefixes
list in case at least gcc 13 is used (it's a gcc-only flag).

This flag used to be part of this list in the past, but was removed with [1].

Since then the source file paths are not canonicalized, which makes
the system to miss some (and sometimes all) source files to include
in the corresponding -src packages. As an example sqlite3 and audiofile
(from meta-oe) produces empty src packages, mostly due to the pathes:
they frequently use relative paths that don't match up with the
absolute path specified in the file-preifx map:
`pwd`/../../foo.cpp and ${S}/foo.cpp might refer to the same file, but
the first one won't match the prefix-map, so it is omitted.

This patch adds this option again with gcc: for class-target it is uses
always, and for class-native it is used when the host gcc is at least
version 13.

[PATCH 2/2] rust-common.bbclass: filter out incorrect compiler flags in wrapper

[Gyorgy Sarvari]

This patch is a workaround for https://bugzilla.yoctoproject.org/show_bug.cgi?id=15976

cc-rs crate is used by a number of projects, including rust's bootstrap also
to invoke the systems c/c++ compiler.

A few updates ago it has changed the way CFLAGS/CXXFLAGS are handled: it now
merges them with HOST_C*FLAGS and TARGET_C*FLAGS.

This is a problem when a recipe is cross compiled, but it has a build dependency
which uses this crate to be built. In this case the C*FLAGS variable contains
target flags, while the HOST_C*FLAGS contains host-specific flags, and when the
two are mixed, the output is not what one expects.

This change tries to filter out the incorrect flags:
- If the wrapper is invoked as a c or c++ compiler wrapper,
- then determines if it compiles for host or for target
- Depending on the on above, it considers the TARGET_*FLAGS or HOST*FLAGS
  correct, and the C*FLAGS variable content incorrect.
- It subtracts the correct set from the incorrect set, and drops the
  remainder from the compiler flags. (Which might be often an empty list, so
  the flags are frequently unchanged)

I think we should do something like this patch but just with only the
target pieces, not the native ones.

The gcc version check is a slow function call since it execs a command
and we really don't want a call like that dropped inside a variable.

native components don't have -src packages so I'm not sure we need that
element of this. The simplest thing would be to drop that piece.

This issue was identified as a release blocker so I'll probably hack
the patch and put something into master-next for testing overnight.

Cheers,

Richard

cc-rs is perhaps the problematic bit, if thats sorted with the second patch
then I agree, we can keep it from target alone.

Re: [OE-core] [PATCH 1/2] bitbake.conf, gcc toolchain: add -fcanon-prefix-map to map-prefixes

Please try the v2 of the cc-rs patch - I see that v1 got into
master-next, but it will fail selftests.

Re: [OE-core] [PATCH 1/2] bitbake.conf, gcc toolchain: add -fcanon-prefix-map to map-prefixes

[Martin Jansa]

I think we also need weak assignment DEBUG_PREFIX_MAP_EXTRA to empty
in bitbake.conf, because the unexpanded variable with clang instead of
gcc (with v2 from ML as well as the version currently in master-next)
causes:

Yes, I did already:
https://lists.openembedded.org/g/openembedded-core/message/226640 - I
believe this should take care of this issue
(but I have to admit that currently I struggle executing the selftest on
my machine - both inside and outside of docker I get mysterious qemu
startup errors).
