The softfloat function floatx80_round_to_int incorrectly handles the case of a pseudo-denormal where only the high bit of the significand is set, ignoring that bit (treating the number as an exact zero) rather than treating the number as an alternative representation of +/- 2^-16382 (which may round to +/- 1 depending on the rounding mode) as hardware does. Fix this check (simplifying the code in the process).

These are i386 specific guest programs test-i386 --------- This program executes most of the 16 bit and 32 bit x86 instructions and generates a text output, for comparison with the output obtained with a real CPU or another emulator. The Linux system call modify_ldt() is used to create x86 selectors to test some 16 bit addressing and 32 bit with segmentation cases. The Linux system call vm86() is used to test vm86 emulation. Various exceptions are raised to test most of the x86 user space exception reporting. linux-test ---------- This program tests various Linux system calls. It is used to verify that the system call parameters are correctly converted between target and host CPUs. test-i386-fprem --------------- test-mmap --------- sha1 ---- hello-i386 ----------
