[Qemu-devel] [PATCH] Handle .LCn symbols in dyngen

2005-06-02 Thread Gwenole Beauchesne
Hi, sparc-user build fails on x86_64 with gcc4 because op_fnegs() uses a local constant (0.0) and dyngen can't emit it. Before I realized Paul fixed this in his former gcc4 patch with a helper call (which is not in the final gcc4 patch), I merged the following from the SheepShaver dyngen. Note: I

[Qemu-devel] [PATCH] Fix gcc4 patch

2005-06-02 Thread 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). 2005-06-02 Gwenole Beauchesne <[EMAIL PROTECTED]>

"Arm is still the only target that really takes advantage of any of the new functionality." Sorry I missed this line :( I hope you will still consider x86 target before x86-64. You'd get a broader audience for testing/debug. If so, let us know. I haven't switched to svn yet... Thanks anyway Chri
