[Qemu-devel] qemu regression 0.7.2 -> 0.8.0 (ARM user emulation)

["Anderson Lizardo" <anderson.lizardo@gmail.com>]

Hi,

I was having some issues with the latest qemu (ARM user emulation),
which I tracked down to the following reduced test case:

#include <stdio.h>
int main(void)
{
        float a, b;
        a = 0.1f;
        b = 0.8f;
        printf("a < b: %d\n", (a < b));
        return 0;
}

Compile it with an ARM cross-compiler and run it with "qemu-arm". It
should print

a < b: 1

for qemu 0.7.2 and

a < b: 0

for 0.8.0. Obviously, the first one is right.

Tested with the following setup:
qemu 0.7.2/0.8.0
arm-linux-gnu-gcc (GCC) 3.4.5
glibc 2.3.5
