SVE Support ([VIRT-198])


  - traced the svetest failure from Naoki @ Naist to SVE ABI issue with
dynamic linker
- rth has posted [a fix for glibc] and a bug raised for armclang
  w.r.t. noplt
  - looking into Nils's SVE enabled Test_simd from Grid failure
- __attribute__((noinline)) makes it go away, so subtle code
  difference
- looking through side-by-side traces to find where it went wrong

  - had a [quick run at VHE] which crystallised some of the issues with
register aliasing
- obviously need to sit and think about a design for this

[ACTIVITY] report week ending 3 Aug

2018-08-03 Thread Peter Smith 
[TCWG-1450] Support for Tag_ABI_VFP_args in LLD
Needed by FreeBSD in order to switch to LLD for Arm.

[TCWG-1451] Support for v5 and v6 Arm in LLD
Tidied up and submitted patches for v5/v6 (branch encoding and
compatible thunks), in upstream review.

[TCWG]
- Started doing some Jira gardening in preparation for status report
- Went back to libfuzzer hang on AArch64 buildbot. Looks like failure
to converge on -O2 and above, from the logs and code-generation I
suspect that it isn't handling the CINC instruction well (not
increasing coverage when the condition passes).

2018-08-03 Thread Peter Maydell 
Progres:s
 * VIRT-65 [QEMU upstream maintainership]
   + some time spent getting testing on BSD VMs working again (the box I
 use for this was replaced with new hardware, which seemed like a good
 time to shift to the support for this we have in upstream QEMU)
   + pre-Connect scrub of Linaro JIRA tasks to check they're up to date
   + sent some more "convert devices away from old_mmio API" patches
   + usual release work
 * VIRT-164 [improve Cortex-M emulation]
   + finished, tested and sent patchset implementing MPS2 FPGAIO counters
 and the CMSDK dual-timer device
   + implemented model of CMSDK watchdog timer
   + implemented minimal version of IoTKit system control element registers
   + started on modelling the Master Security Controller (which gates
 transactions from bus master peripherals like DMA controllers)

thanks
