[ACTIVITY] 17-21 December 2018

2018-12-21 Thread Christophe Lyon 
== Progress ==
* FDPIC
- (GNU-499) GCC: wait for feedback on v4 patches
- (GNU-411) GDB: it seems qemu's gdbstub needs patches to support
packets needed by fdpic. Tried to build gdbserver for fdpic, but the
code base changed a lot since our original port.

* GCC upstream validation:
- reported a few regressions
- dealing with some random results, still
- qemu-3.1.0-rc3, memory consumption: no time to really look at the
problem. Unable to match time's figures with LSF's

* GCC:
- (GNU-99) rebased ubsan / bare-metal patches. Using gcc-built
libubsan worked with an in-house llvm-based toolchain. POC is OK, but
a clean implementation is still far.

* misc (conf-calls, meetings, emails, )
- reviewing/submitted infra script patches
- dealing with nasty ST-internal infrastructure problems
- (GNU-592): improved benchmarking scripts
- looking at new build servers configs

== Next ==
FDPIC:
- GCC: handle feedback on v4 patches
- GDB: update patches
- uclibc-ng: look at how to test fdpic mode with openadk

Validation:
- isolate if/why qemu-3.1.0-rc3 consumes more memory than 2.11 for
aarch64-linux target
