Bug ID: 16384
Summary: -Wformat highlights incorrect range when using
cinttypes macros
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Example:
⑆ cat main.cpp
#include <cstdio>
#include <cstdint>
#include <cinttypes>
int main() {
std::printf("%" PRIu32 "\n", std::uint64_t{100});
}
⑆ clang++ -std=c++11 -stdlib=libc++ -Wall main.cpp
main.cpp:6:32: warning: format specifies type 'unsigned int' but the argument
has type 'std::uint64_t' (aka 'unsigned long long') [-Wformat]
std::printf("%" PRIu32 "\n", std::uint64_t{100});
~~~ ^
1 warning generated.
Expected results:
std::printf("%" PRIu32 "\n", std::uint64_t{100});
~~~~~~~~~ ^
The highlighting for the argument might also be improved:
std::printf("%" PRIu32 "\n", std::uint64_t{100});
