Bug ID: 111790
Summary: Unwarranted missing template keyword warning
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: t.bart...@tu-berlin.de
Target Milestone: ---
Consider the following code:
template <typename T> //no warning if this is not a template
struct X
{
T v;
};
template <typename T>
inline void f() {
X<T> x; //no warning with e.g. X<int>
if(x.v < 0 &&
0 > -1) {} //No warning without the "-"
}
int main() {
f<int>(); //Still get a warning without this instantiation.
}
GCC 12, 13, current trunk and seemingly everything after b8ffa71e427 give me a
warning for this:
warning: expected 'template' keyword before dependent template name
[-Wmissing-template-keyword]
But GCC compiles it, so it seems to interpret it correctly at some point after
triggering the warning. I tried to look into it and thought that maybe
cp_lexer_peek_token (parser->lexer)->type
<= CPP_LAST_PUNCTUATOR
in line 6447 of gcc/cp/parser.cc is too general but I do not have a proposed
patch.
