This patch converts the function signatures to havea prototype for the situations where the test is not specific to K&R Cdeclarations. e.g., void func();becomes void func(void);This is the second batch of tests being updated (there are a significantnumber of other tests left to be updated).

(even though theDWARF doesn't have this string in it - it's something to do with thestring lldb generates for itself using clang)This reverts commit 277623f4d5a672d707390e2c3eaf30a9eb4b075c.

That's non-conforming, and more modern versions ofGCC only do this at file scope. Update Clang to do the same.Also promote the warning for this from off-by-default to on-by-defaultin all cases; more recent versions of GCC likewise warn on this bydefault.This is still slightly more permissive than GCC, as pointed out inPR44406, as we still fold VLAs to constant arrays in structs, but thatseems justifiable given that we don't support VLA-in-struct (and don'tintend to ever support it), but GCC does.Differential Revision: https://reviews.llvm.org/D89523 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Fri, 16 Oct 2020 02:32:15 +0000 Richard Smith <richard@metafoo.co.uk> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/gnu-flags.c#62695611 Add specific warning flags for GNU ext in Sema.This patch adds the following, more specific warning flags:gnu-anonymous-structgnu-compound-literal-initializergnu-empty-structgnu-flexible-array-initializergnu-flexible-array-union-membergnu-folding-constantredeclared-class-membergnu-redeclared-enumgnu-union-castgnu-variable-sized-type-not-at-endPatch by Peter Lewis.llvm-svn: 190972 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Wed, 18 Sep 2013 23:23:17 +0000 Eli Friedman <eli.friedman@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/gnu-flags.c#56fde966 gnu-flags.c test: relax the check a bitThis tests warning flags, so no need to test for specific alignment which isplatform-dependent.llvm-svn: 188993 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Thu, 22 Aug 2013 08:13:43 +0000 Dmitri Gribenko <gribozavr@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/gnu-flags.c#4633cd7b Tweak gnu-flags.c test for z, where globals have 2-byte alignment by defaultllvm-svn: 188905 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Wed, 21 Aug 2013 16:37:37 +0000 Richard Sandiford <rsandifo@linux.vnet.ibm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/gnu-flags.c#85698c8d Remove Extension warning for GNU local labels.We generally don't warn about extensions involving keywords reservedfor the implementation, so we shouldn't warn here either: thestandard doesn't require it, and it doesn't provide useful informationto the user.llvm-svn: 188840 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Tue, 20 Aug 2013 22:44:32 +0000 Eli Friedman <eli.friedman@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/gnu-flags.c#571c3ae7 Add more specific flags for misc GNU extensions.This adds the following as subgroups of -Wgnu: -Wgnu-alignof-expression,-Wgnu-case-range, -Wgnu-complex-integer, -Wgnu-conditional-omitted-operand,-Wgnu-empty-initializer, -Wgnu-label-as-value, -Wgnu-local-label,and -Wgnu-statement-expression,Patch by Peter Lewis.llvm-svn: 188839 List of files: /llvm-project-15.0.7/clang/test/Sema/gnu-flags.c Tue, 20 Aug 2013 22:44:28 +0000 Eli Friedman <eli.friedman@gmail.com>
