2010-06-09target-mips: add microMIPS exception handler supportNathan Froyd2-6/+16
Unlike MIPS16, microMIPS lets you choose the ISA mode for your exception handlers. The ISA mode is selectable via a user-writable CP0.Config3 flag. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-09target-mips: microMIPS ASE supportNathan Froyd4-5/+2531
Add instruction decoding for the microMIPS ASE. All we do is decode and then forward to the existing gen_* routines. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-09target-mips: mips16 cleanupsNathan Froyd1-7/+17
Change code handling mips16-specific branches to use ISA-neutral special opcodes. Since there are several places where the delay slot requirements for microMIPS branches differ from mips16 branches, using opcodes is easier than checking hflags, then checking mips16 vs. microMIPS.

2010-06-09Fix multiboot compilationAlexander Graf2-12/+28
Commit dd4239d6574ca41c94fc0d0f77ddc728510ffc57 broke multiboot. It replaced the instruction "rep insb (%dx), %es:(%edi)" by the binary output of "addr32 rep insb (%dx), %es:(%di)". Linuxboot calls the respective helper function in a code16 section. So the original instruction was automatically translated to its "addr32" equivalent. For multiboot, we're running in code32 so gcc didn't add the "addr32" which breaks the instruction. This patch splits that helper function in one which uses addr32 and one which does not, so everyone's happy. The good news is that nobody probably cared so far. The bundled multiboot.bin binary was built before the change and is thus correct. Please also put this patch into -stable.

2010-06-09tcg: Add TYPE parameter to tcg_out_mov.Richard Henderson12-123/+122
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR. Update all targets to match. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-06-01Monitor: Drop QMP documentation from codeLuiz Capitulino9-368/+0
Previous commit added QMP documentation to the qemu-monitor.hx file, it's is a copy of this information. While it's good to keep it near code, maintaining two copies of the same information is too hard and has little benefit as we don't expect client writers to consult the code to find how to use a QMP command.

2010-06-01QMP: Introduce commands documentationJan Kiszka5-4/+1376
One of the most important missing feature in QMP today is its supported commands documentation. The plan is to make it part of self-description support, however self-description is a big task we have been postponing for a long time now and still don't know when it's going to be done. In order not to compromise QMP adoption and make users' life easier, this commit adds a simple text documentation which fully describes all QMP supported commands. This is not ideal for a number of reasons (harder to maintain, text-only, etc) but does improve the current situation. To avoid at least divering from the user monitor help and texi snippets, QMP bits are also maintained inside qemu-monitor.hx, and hxtool is extended to generate a single text file from them.
