Here is the results of trying to compile the program
On x86 32 bit architecture with C or C++ program clang fails to compile a
program with a long long argument passed to a function following a for
statement
to set the long long.
This works in 64 bit mode. The problem is only when using optimization levels
from -O to -O3. Without optimization or with -O4 the program compiles
successfully.
The program can be compiled with
clang -m32 -c -O clangfail.c
It will also fail with
clang++ -m32 -c -O clangfail.c
Following is the C file that causes the problem:
/*-----------------------------------------*/
void myfprintf(long long);
void integer_work(long count)
{
long long i;
long long result = 0;
for (i=1; i <= count; i++) {
result+=i;
}
myfprintf(result);
}</pre>
