[ACTIVITY] report week ending 20 Apr

2018-04-20 Thread Peter Maydell 
Progress:
 * VIRT-65 [QEMU upstream maintainership]
   + sent another patch related to linux-user signal frames (a wrinkle
 I had thought had no effect with SVE disabled turns out to be
 relevant in the no-SVE case too)
   + testing and applying patches for 2.12 rc4
   + code review:
 - latest spin of the SMMUv3 emulation patches
 - some last-minute fixes to our softfloat refactoring
 - memory barrier handling in the 32-bit arm TCG backend was broken
   + tracked down a zephyr test failure on QEMU as the same bug in
 the Zephyr timer device driver as the one I reported 6 months ago...
   + sent a patch fixing linux-user emulation of getdents syscall for
 64-bit guest on 32-bit host
   + sent a patchset that removes the long-standing "only 4 serial ports"
 limit in QEMU (various Arm boards really have 5 or 6)
   + some patches fixing errors in arm boards that don't properly
 register all their RAM regions for migration

thanks

[ACTIVITY] Weekly report for week 16

2018-04-20 Thread Thomas Preudhomme 
=== Work done during this GCC week ===

* TCWG-1379 (stack-protector failure on GCC ARM): need feedback from
community
  + reproduce on trunk and find out why it happens on ARM and not AArch64
or x86
  + find potential issue for all targets as well, though less likely
  + find discrepencies between code and documentation and wondered if code
is not overly zealous in some case
* 2 days doing Arm handover & meetings


=== Plan for next week (week 12) ===

* Progress on stack-protector failure
* Support arithmetic on FileCheck regex variable: finish patch

[ACTIVITY] week ending 20th April 2018

2018-04-20 Thread Peter Smith 
Progress:
Monday Tuesday at Euro LLVM, trip report at
https://collaborate.linaro.org/display/CR/20180416+EuroLLVM+2018

Found an example that shows that both gold and ld attempt to fix up
illegal "by strict interpretation of ELF" local debug references to
discarded local symbols from rejected comdat groups.

[TCWG-1375] LLVM should do relaxation per function.
- Worked out what instruction bundling is (From NaCl) and how it
relates to MCFragments.
- Posted revised patch upstream to handle relaxation and fixups, now
diagnoses attempt to change MCSubtargetInfo mid bundle.
- I have a finished a large series of patches to pass the
MCSubtargetInfo through to all the places it needs to be including
writeNops. Will post upstream review next week.

Next week:
- Post revised patches to TCWG-1375 and ping reviews.
- Work through a laundry list of small things to do in LLD.
- Get back to trying to link Android AOSP with LLD.
