[Qemu-devel] [PATCH] Fix gcc4 patch

[Gwenole Beauchesne]

Hi,

I got a "No return instruction found in op_lmsw_T0" when building qemu
with the gcc4 patch + gcc3.3. push imm8 was misdecoded. Also fixed the
imul case at the same time.

Tested with gcc 3.3.4 (hammer-branch), 3.4.3, 4.0.1 (4.0-branch).

        * dyngen.c (trace_i386_insn): Fix push/imul case with 8-bit
        immediate.
