Ok, let me fix that too, then. I've updated the description to show
what we print with the patch, and what was printed before.
And I also noticed another thing: type_hash_canon_hash hashes only
get_attribute_name, so build_type_attribute_qual_variant will use the
same function_type tree for these two pointers:
__attribute__((nocf_check)) typedef void (*fp1)();
[[gnu::nocf_check]] typedef void (*fp2)();
so if gcc prints a diagnostic with fp2, it will show the GNU form of
the attribute, because the already existing type of fp1 will be used!
I'm not addressing it here, just an oddity I discovered.
Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?
-- >8 --
When getting the name of an attribute, we ought to use
get_attribute_name, which handles both [[]] and __attribute__(())
forms. Failure to do so may result in an ICE, like here.
pp_c_attributes_display wasn't able to print the [[]] form of
attributes, so this patch teaches it to.
When printing a pointer to function with an attribute, the attribute
should be printed after the *, because that's what it appertains to.
With this patch we print:
aka 'void (*__attribute__((nocf_check)))()'
aka 'void (*[[gnu::nocf_check]])()'
rather than
aka 'void (__attribute__((nocf_check)) *)()
or crashing in the second case.
pp_c_attributes has been unused since its introduction in r56273 so
this patch removes it.
PR c++/106937
gcc/c-family/ChangeLog:
* c-pretty-print.cc (pp_c_specifier_qualifier_list): When
printing a pointer to function with an attribute, print the
attribute after the *.
(pp_c_attributes): Remove.
(pp_c_attributes_display): Print the [[]] form if appropriate.
Use get_attribute_name. Don't print a trailing space.
* c-pretty-print.h (pp_c_attributes): Remove.
gcc/cp/ChangeLog:
* error.cc (dump_type_prefix): When printing a pointer/reference to
function with an attribute, print the attribute after the */&.
gcc/testsuite/ChangeLog:
* g++.dg/diagnostic/aka5a.C: Adjust.
* g++.dg/diagnostic/aka5b.C: Likewise.
* gcc.dg/diag-aka-5a.c: Likewise.
* gcc.dg/diag-aka-5b.c: Likewise.
* c-c++-common/pointer-to-fn1.c: New test.
