Bug ID: 18670
Summary: Bad warning for 'void f(int[] x)'
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: chris at bubblescope.net
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
If a user accidentally writes an array argument for a function in java style
(int[] x) rather than C (int x[]), the warning is fairly confusing:
void f(int[] x);
y.c:1:14: error: expected ')'
void f(int[] x)
^
y.c:1:7: note: to match this '('
void f(int[] x)
^
y.c:1:11: error: parameter name omitted
void f(int[] x)
^
By the last line we are getting slightly clearer what is going on, but this
still confuses a few of my students (who move from being taught Java to C) each
year.
