I created the following test, mimicking the game's behavior: unsigned long x86_fpword = 0x0031047f; unsigned long sse_fpword = 0x3fa1; __asm__ __volatile__( "fldcw %0" : : "m" (x86_fpword) ); // load __asm__ __volatile__( "ldmxcsr %0" : : "m" (sse_fpword) ); // load _control87(0x100, 0x300); __asm__ __volatile__( "fstcw %0" : "=m" (x86_fpword) ); // store __asm__ __volatile__( "stmxcsr %0" : "=m" (sse_fpword) ); // store printf("Modified: x86=%08x sse=%08x\n", x86_fpword, sse_fpword); This returns: Modified: x86=0031047f sse=00003fa1 Under native msvcrt, but the wine's version (before the patch) returned this: Modified: x86=0031047f sse=00003f80 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
