== Progress ==
- releases (3/10)
* GCC 4.7 and 4.8 releases done
* more cbuild2 feedback
- cross-validations (2/10)
* followup
* adding capability to test a patch over a given revision on several
targets/cpu/fpu/runtestflags
- libsanitizer on AArch64 (3/10)
* most tests are now functional
* still some errors in the GCC testsuite, to be analyzed (there are
some timeouts, too despite using SSH multiplexing to the Foundation
model)
- misc (2/10): conf-calls and meetings
== Next ==
- libsanitizer on AArch64: analyze errors, try QEMU
== Future ==
On sick leave starting Feb 11th
== Progress ==
* Libc probes support for Aarch64 (2/10).
Wrote a small patch for setjmp and longjmp LIBC probe.
Requested "will newton" to test them .
* Investigate "PGO" for Aarch64 (3/10).
Bootstap testing GCC with PGO for GCC.
Stage 2, feedback profile in progress.
Ran coremark on foundation model with PGO.
The benchmark builds with profile-generate and runs.
"gcda" files are generated and uses them to profile.
Profile generated runs does not run cleanly.
Cross checking if the generated profile is valid.
* Resubmmited libssp machine description support in GCC (2/10).
* Cbuild2 discussed with rob, ryan on SYSROOT installation while building (1/10)
cross compiler for aarch64. "SYSROOT" is expected to be in
/opt/linaro, but cbuild2 does not do this by default.
Misc (1/10)
-------------
AMD internal meetings and did some investigations
== Plan ==
- Run EMBCC benchmarks with -PGO enabled.
- Follow up upstream libssp GCC discussions.
* 4 days week (university).
== Issues ==
* none
== Progress ==
* LRA on AArch32:
o TCWG-343 : Make LRA the default for the ARM backend (3/10)
- Looking backend places (ARM and AArch64) where reload_in_progress
is used to verify if lra_in_progress is needed as well: Tested lot of
configurations, testsuite results analysis ongoing.
o TCWG-345 : Analyse performance of LRA for ARM. (0/10)
- No progress this week.
* GMP library AArch64 port review: (4/10)
o Analyzing code generated from C generic implementation vs assembly.
* Misc. (1/10)
o Various meetings.
== Next ==
* Child care (chickenpox)
* Still some time spend at university
* Continue on LRA and lib GMP
== Progress ==
* Implemented per process hwbreakpoint and watchpoint cache for arm
native targets.
Also added a reference count for per thread hardware breaks. [TCWG-177] [7/10]
* Travelled to Islamabad for Macau visa application. [3/10]
== Plan ==
* Continue work on forking/vforking hardware breakpoints support for arm-native.
Tweak hardware breakpoint cache and thread breaks reference count to
get it in sync with linux-native. [TCWG-177]
== Misc ==
- Monday 27/01/2014 - Public holiday
== Progress ==
- LP#1191909: gold and -flto always fails with an internal error on
arm-linux-gnueabi* (2/10)
- Reproduced it and Looking into the implementation for best fix.
-c11-atomic-exec-5.c (4/10)
- Issue is due to missing target hook and looking at implementing
-LP#1270789: gcc 4.8: "invalid expression as operand" in aarch64
inline asm (2/10)
- came-up with the patch. Still in the process of testing it. APM1
disc seems to be corrupt and that is holding this.
- Benchmarking (1/10)
- added -pgo for coremark
- Set-up a Linux desktop (1/10)
== Plan ==
- Continue with trunk daily regression
- Fix assigned bugs
== Progress ==
* Improve binary releases produced by Cbuildv2. (6/10 TCWG-383)
* Minor changes to source releases produced by Cbuildv2. (1/10)
* Added support to Cbuild to use lsbcc for binary releases. (1/10)
* Meetings. (1/10)
* Started reviewing Kugan's benchmarking branch of Cbuildv2. (1/10)
== Plan ==
* Build static gdbserver for target via Cbuildv2.
* Add Win32 installer for Canadian cross built binary
releases to Cbuildv2. (TCWG-381)
* Once Jenkins has a node_selector for the new Beagle Board Blacks,
get those working for native builds. (TCWG-379)
* Get QEMU and Foundation Model running on TCWG x86_64 build slaves
so Jenkins can use them for native builds. (TCWG-380)
== Progress ==
* Add support for AArch32 ARMv8 16<->64bit VCVT to QEMU (2/10, TCWG-51)
* Triage and report AArch64 gcc bug when building glibc with SystemTap (1/10)
* Debug and submit patch for ARM libffi issue (1/10)
* Add support for longjmp/setjmp Systemtap probes on ARM (4/10, TCWG-378)
* Ported Python cffi package to AArch64, submitted upstream (1/10)
* Fixed bug building glibc for armv4 (1/10)
== Issues ==
* Broadband down for 3 hours on Wednesday afternoon
== Plan ==
* Follow up QEMU patches and maybe post v2
* malloc
