Bug ID: 27613
Summary: Wrong end location for -Winitializer-overrides with
overridden initializers
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: chere...@mccme.ru
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Source code:
----------------------------------------------------------------------
int main()
{
struct s { int x, y; } s1 = { 1, 2 };
struct { struct s sub; int z; } s2 = { .sub = s1, .sub = 3, 4, 5 };
(void)s2;
}
----------------------------------------------------------------------
Results:
----------------------------------------------------------------------
$ clang -std=c11 -Weverything -O3 test.c && ./a.out
test.c:4:60: warning: subobject initialization overrides initialization of
other fields within its enclosing subobject [-Winitializer-overrides]
struct { struct s sub; int z; } s2 = { .sub = s1, .sub = 3, 4, 5 };
^~~~~~~~~
test.c:4:49: note: previous initialization is here
struct { struct s sub; int z; } s2 = { .sub = s1, .sub = 3, 4, 5 };
^~
test.c:4:60: warning: suggest braces around initialization of subobject
[-Wmissing-braces]
struct { struct s sub; int z; } s2 = { .sub = s1, .sub = 3, 4, 5 };
^~~~
{ }
2 warnings generated.
----------------------------------------------------------------------
clang version: clang version 3.9.0 (trunk 268228)
The first warning underlines "3, 4, 5 }". I think it should underline "3, 4"
only.
