I noticed that GCC/Rust recently lost all LTO variants in torture testing:
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O0 (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O1 (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 (test for excess errors)
-PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 -flto -fno-use-linker-plugin -flto-partition=none (test for excess errors)
-PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O3 -g (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -Os (test for excess errors)
Etc.
The reason is that when probing for availability of LTO, we run into:
spawn [...]/build-gcc/gcc/testsuite/rust/../../gccrs -B[...]/build-gcc/gcc/testsuite/rust/../../ -fdiagnostics-plain-output -frust-incomplete-and-experimental-compiler-do-not-use -flto -c -o lto8274.o lto8274.c
cc1: warning: command-line option '-frust-incomplete-and-experimental-compiler-do-not-use' is valid for Rust but not for C
For GCC/Rust testing, this flag is (as of recently) defaulted in
'gcc/testsuite/lib/rust.exp:rust_init':
lappend ALWAYS_RUSTFLAGS "additional_flags=-frust-incomplete-and-experimental-compiler-do-not-use"
A few more "command-line option [...] is valid for [...] but not for [...]"
instances were found in the test suite logs, when more than one language is
involved.
With '-Wno-complain-wrong-lang' used in
'gcc/testsuite/lib/target-supports.exp:check_compile', we get back:
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O0 (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O1 (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 (test for excess errors)
+PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 -flto -fno-use-linker-plugin -flto-partition=none (test for excess errors)
+PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -O3 -g (test for excess errors)
PASS: rust/compile/torture/all_doc_comment_line_blocks.rs -Os (test for excess errors)
Etc., and in total:
=== rust Summary for unix ===
# of expected passes [-4990-]{+6718+}
# of expected failures [-39-]{+51+}
Anything that 'gcc/opts-global.cc:complain_wrong_lang' might do is cut
short by '-Wno-complain-wrong-lang', not just the one 'warning'
diagnostic. This corresponds to what already exists via
'lang_hooks.complain_wrong_lang_p'.
The 'gcc/opts-common.cc:prune_options' changes follow the same rationale
as PR67640 "driver passes -fdiagnostics-color= always last": we need to
process '-Wno-complain-wrong-lang' early, so that it properly affects
other options appearing before it on the command line.
