Summary: clang: sizeof(int16_t) != 2
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Semantic Analyzer
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [email protected]
Compile the below testcase with clang, it aborts on Linux x86-64:
#include <stdlib.h>
#include <stdint.h>
int main()
{
if(sizeof(int16_t) != 2)
abort();
}
$ /home/edwin/llvm-svn/llvm/tools/clang/utils/ccc foo.c
foo.c
clang -emit-llvm-bc -o foo.o foo.c
llvm-ld -native -disable-internalize -o a.out foo.o
$ ./a.out
Aborted
Look at the declarations of int16_t from the headers, I think that attribute is
not handled.
/home/edwin/llvm-svn/llvm/tools/clang/utils/ccc foo.c -E|grep int16_t
typedef signed short int __int16_t;
typedef unsigned short int __uint16_t;
typedef int int16_t __attribute__ ((__mode__ (__HI__)));
typedef unsigned int u_int16_t __attribute__ ((__mode__ (__HI__)));
typedef unsigned short int uint16_t;
if(sizeof(int16_t) != 2)
