Bug ID: 25110
Summary: "Implicit int" is still available for function
parameters in C99
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: mimomo...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
A legacy "implicit int" feature of was removed in C99.
But Clang still allows it for function parameters (e.g. `void f(x) {}`)
and produces no warnings unless `-pedantic` is specified.
Clang should produce warnings (at least).
For reference, here is a list of "implicit int" warnings/errors in C99 mode:
void f(x) {};
[no warning!]
void g(x);
[error]
a parameter list without types is only allowed in a function definition
x;
[warning]
type specifier missing, defaults to 'int' [-Wimplicit-int]
(gcc produces warnings for all the three cases.)
