The function AO_test_and_set_full fails to build with the following
error:
test.s: Assembler messages:
test.s:38: Error: bad register name `%sil
This only occurs when compiling with the -O0 flag using gcc 4.0.
It did not occur with gcc 3.3 nor does it occur when using -Os,
-O1, -O2 or -O3.
A minimal test file and the exact build command I used are below:
gcc-4.0 -march=i386 -mtune=i386 -O0 -Wall -Wno-long-long -save-temps -c test.c
#include <atomic_ops.h>
int main()
{
volatile AO_TS_t x = 0;
AO_test_and_set_full(&x);
}
