2009-12-13target-mips: fix user-mode emulation startupNathan Froyd2-8/+8
Running programs with the MIPS user-mode emulator fails during dynamic loading, as floating-point instructions are not enabled in in env->hflags. Move the code for doing so from fpu_init to cpu_reset so the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset setting env->hflags to MIPS_HFLAG_UM. The same end can be achieved by swapping the ordering of fpu_init and cpu_reset in cpu_mips_init, but it seemed better to consolidate the CONFIG_USER_ONLY code into a single location.

2009-12-13target-i386: Update CPUID feature set for TCGAndre Przywara1-13/+12
The CPUID features QEMU presented to the guest were not up-to-date with QEMU's emulated feature set. Add the missing bits of recent (and not so recent) additions to QEMU's emulation engine. For stability reasons only the user mode usable bits are exposed for now, features like Monitor or CR8LEG are left out.

2009-12-13target-alpha: Fixes for alpha-linux syscalls.Richard Henderson6-49/+468
1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.

2009-12-13target-mips: add mips16 instruction decodingNathan Froyd1-9/+1063
There's no good way to add this incrementally, so we do it all at once. The only changes to shared code are in handle_delay_slot. We need to flip ISAMode when doing a jump-and-exchange. We also need to set ISAMode the low bit of the target address for jump-to-register. Also, since we're now adding bits that can be in MIPS_HFLAG_BMASK_EXT, make sure we use MIPS_HFLAG_BMASK_BASE in the places where we just want basic information about a branch.

2009-12-13target-mips: move ROTR and ROTRV inside gen_shift_{imm, }Nathan Froyd1-139/+148
It's easier to implement mips16 shift instructions if we're not examining the opcode inside gen_shift_{imm,}. So move ROTR and ROTRV and do the special-case handling of SRL and SRLV inside decode_opc. Likewise for their 64-bit counterparts.

2009-12-13target-mips: add new HFLAGs for JALX and 16/32-bit delay slotsNathan Froyd1-19/+28
We create separate masks for the "basic" branch hflags and the "extended" branch hflags and define MIPS_HFLAG_BMASK as the logical or of those two. This is done to avoid churning the codebase in lots of different places. We also make the execution mode an hflag under MIPS_HFLAG_TMASK Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13workaround for cmd646 bmdma register access while no dma is activeIgor V. Kovalenko3-5/+4
This is a workaround only, and is a partial revert of a few changes to BMDMAState which removed pci_dev field on the way. - cmd646 pci_from_bm() expects bm->unit value to correspond with bm data being passed to callback as opaque pointer. This breaks when write to dma control register of second channel happens when no dma operation is in progress, so bm->unit is zero for second channel, and pci_from_bm() returns garbage pointer. Crash happens shortly after that while dereferencing that pointer. v0->v1: cleaned up dead code from pci_from_bm. Signed-off-by: Igor V.
